Let op het systeem kun je niet resetten door de accu los te koppelen.

Het registreert de fout en houdt deze vast, kan alleen met een diagnose systeem worden gereset.

Dit is wat VADIS erover verteld (phase 1, phase 2 is nog uitgebreider)

Diagnostic trouble codes (DTCs), status, counters and frozen values can be read and erased with this function.
Diagnostic trouble codes (DTCs) cannot be erased until they have been read off at least once and the cause of the fault has been remedied.
For a list of diagnostic trouble codes (DTCs) and fault-tracing, see Diagnostic trouble codes (DTCs) table .
Connect Volvo Scan Tool (ST) in accordance with Volvo Scan Tool (ST) .
Diagnostic trouble codes (DTCs) can be posted for the following faults in airbag/seat belt tensioner circuits:

-short-circuit
-open-circuit
-short-circuit to ground
-short-circuit to supply voltage
-high capacitance
-low capacitance.

Diagnostic trouble codes (DTCs) can be posted for the following faults in the SRS warning lamp circuit:

-open-circuit or short-circuit to ground
-short-circuit to supply voltage.

Parameter values (status or frozen values) are stored for the following:

-steering wheel module circuit
-passenger module circuit
-left seat belt tensioner circuit
-right seat belt tensioner circuit
-SRS warning lamp circuit
-back-up power
-voltage X-supply
-voltage level D+
-internal fault in the SRS sensor module (in EEPROM, RAM and ROM for example).

Phase 2

The primary task of the supplemental restraint system module (SRS) is to minimize injuries to the driver and passengers in the event of different types of accident. To do this, the control module validates incoming pulsed collision signals (acceleration signals generated by a collision) and then determines the required action.
The control module uses internal sensors as well as external collision sensors. Using the data collected from the sensors, the system determines which of the following will be activated:

*front airbags
*side impact protection (SIPS) bags
*inflatable curtains
*seat belt tensioners.

The collision sensor in the control module registers the longitudinal mechanical stress that occurs in a frontal collision. A side impact may also be registered in the collision sensor. The longitudinal stresses are measured using two acceleration sensors. If the longitudinal stresses exceed a certain level, the stress will be calculated (the collision pulse). The calculation evaluates whether the collision pulse was sufficient to activate the airbags and/or the seat belt tensioners. Airbags and seat belt tensioners can be activated individually.

The driver and passenger airbags and the seat belt tensioners are designed to deploy in the event of a frontal collision. There is an electrical switch in the control module to further increase the safety of the system. The switch must be activated in event of a collision for the front airbags to deploy.

When the collision protection system is activated, the control module transmits a pulsed current to the ignition mechanisms in the airbags and/or the seat belt tensioners. No seat belt tensioners or airbags will normally be activated in the event of a collision from the rear.

For the side impact cushion to deploy the collision required must be powerful enough that it is registered by the side impact sensor, as well as the SRS control module registering a collision. If the side impact occurs at the centre of the car, the side impact protection (SIPS) bags and the inflatable curtain are deployed on the side where the collision occurred. If the side impact is towards the rear of the car, normally only the inflatable curtains on that side are deployed. For further information, see Deployment of side impact protection (SIPS) .

The control module has a collision recording function. This records certain system information in the event of up to three collisions. If necessary, this information can be analysed and used after a collision. This information is used in the development of collision safety systems of the future.

There is an internal energy reserve in the control module. This is intended to run the whole system for a short time in the event of a voltage drop. This is to ensure the function of the system, if for example the battery cables should be cut or the battery loses power in some other way during a collision.

In the event of a collision a signal is sent from the SRS control module to the VGLA control module. The intention of the signal is to unlock the doors.

The SRS control module determines whether the airbags or seat belt tensioners should be deployed. This depends on whether:

*if the driver and front passenger are wearing seat belts or not
*if there is a fault in the seat belt buckles.

Information about use of the seat belt buckle for the driver and front passenger comes from the seat belt buckle sensors. If a fault occurs in either the driver or passenger seat belt buckles, a diagnostic trouble code (DTC) is stored locally in the SRS control module.

The SRS (supplemental restraint system) indicator lamp lights when the ignition is switched on. If no faults are registered by the control module, either internally or from the sensors, wiring or igniters, a signal is transmitted to the combined instrument panel confirming that the SRS indicator lamp can be switched off. If a fault occurs, the SRS control module transmits a signal to the combined instrument panel to light the SRS indicator lamp in the combined instrument panel.

Note that after a collision, it may be necessary to replace the wiring for the airbags and seat belt tensioners which deployed. This is because the connectors may melt at the moment of deployment. If a connector has melted, the wiring closest to it must be replaced.

Warning! The ignition must be switched off before any work is carried out on the supplemental restraint system (SRS). The airbags could accidentally deploy if the ignition is switched on.

Side impact sensor




The side impact sensors in the car are used to measure and evaluate the collision pulses. An evaluation is then transmitted to the supplemental restraint system module (SRS).

The sensors which are used in the car are:

*2 side impact sensors in the B-post
*2 side impact sensors in the C-post.

The side impact sensors can transmit three different signals:

*fault in the sensor (Error)
*the sensor is working (OK)
*deployment signal (Fire).

The side impact sensors have integrated logic which, in the event of a collision, determines whether the impact was sufficient to warrant transmitting a trigger pulse to the control module to deploy the side impact airbag. Only the side impact protection on the side from which the signal was sent can normally be deployed.

The side impact sensors transmit continuous OK signals to the control module to indicate that they are working. In the event of a fault in the side impact sensor, a fault signal is transmitted to the control module which then stores a diagnostic trouble code (DTC). A diagnostic trouble code (DTC) is also stored when the control module has not received an OK signal. Each side impact sensor has a software ID. The ID is used to check that the correct side impact sensor is installed. This is because the activation level of the signal which is transmitted to the control module is not necessarily the same for the different side impact sensors.

The front (B-post) and rear (C-post) side impact sensors are a different colour and have different coding on their connectors to simplify installation. The front side impact sensors cannot be installed in place of the rear sensors and vice versa.

There is a memory in the side impact sensors which stores data for up to three collisions.
This information is used in the development of collision safety systems of the future.

Data gearbox occurs on the same cable used for power supply to the side impact sensor. That is a cable for power supply and data gearbox and a ground lead.

Front airbags




Warning! Never use an ohmmeter or similar tool to test airbags or seat belt tensioners. Disconnect airbags or seat belt tensioners before testing them. Failure to do so may result in accidental deployment. This could result in serious injury or death.

The airbags at the front of the car are:

*driver's airbag, 2 stage deployment (introduced model year 2001)
*driver's airbag, 1 stage deployment (model year 1996-2000)
*front passenger airbag, 2 stage deployment (introduced model year 2001)
*passenger airbag, 1 stage deployment (model year 1996-2000).

1 stage deployment (model year 1996-2000)
The driver's airbag contains a pyrotechnical charge and an igniter. During deployment the charge produces a gas consisting mainly of hydrogen and carbon dioxide which expands and fills the airbag. The passenger airbag uses a smaller pyrotechnical charge (12 grams). This is connected to a container filled with argon, helium and oxygen. When the control module deploys the passenger airbag, the pyrotechnical charge heats up the container which then bursts. The airbag is filled by a gas mixture.

2 stage deployment (model year 2001-)
In 2 stage systems, the deployment mechanism for stage 1 is the same for 1 stage types.
Stage 2 contains a pyrotechnic charge.
The front airbags have two powder charge ignition components. These are electrically separated from each other. This means that they have their own separate power supply and grounding points from the control module. Two outputs are required from the control module to the airbag, one to each ignition component of the airbag. This means that four pins are used on the control module, two power supply pins and two ground pins.

2 stage deployment allows for different speed and duration of inflation, depending on the strength of the collision pulse. For safety reasons both stages are used for each deployment. In the event of a lesser impact, there is a greater time delay between stage 1 and stage 2. For more serious impacts the time delay between stages 1 and 2 is shorter.

The airbags are positioned above the glove compartment and in the steering wheel.

There is an igniter for each stage of the airbags and seat belt tensioners. These igniters consist of two pins, a thin ignition wire and an explosive charge. When the SRS (supplemental restraint system) transmits a current pulse the ignition wire heats up and ignites the explosive powder which ignites a gas generator and deploys the airbag.

Warning! Never use an ohmmeter or similar tool to test airbags or seat belt tensioners. Disconnect airbags or seat belt tensioners before testing them. Failure to do so may result in accidental deployment. This could result in serious injury or death.

Side impact air bags




Warning! Never use an ohmmeter or similar tool to test airbags or seat belt tensioners. Disconnect airbags or seat belt tensioners before testing them. Failure to do so may result in accidental deployment. This could result in serious injury or death.

There are two side impact protection (SIPS) bags connected to the SRS (supplemental restraint system) control module. Their connectors are electrically separated from each other. The side impact protection (SIPS) bags are on the outside of the front seats. The side impact protection (SIPS) bags normally deploy on the side of the impact. For further information, see Deployment of side impact protection (SIPS) . The task of the side impact protection (SIPS) bags is to protect the upper body in the event of a side on collision.
The side impact protection (SIPS) bags together with the inflatable curtains and other safety systems can help to protect the driver and front passenger in the event of a collision.

The side impact protection (SIPS) bags use a smaller pyrotechnical charge. This is connected to a container filled with argon and helium. When the control module deploys the side impact protection (SIPS) bag, the pyrotechnical charge heats the container which then bursts. The airbag is filled by a mixture of gas and explosive powder residue.

Warning! Never use an ohmmeter or similar tool to test airbags or seat belt tensioners. Disconnect airbags or seat belt tensioners before testing them. Failure to do so may result in accidental deployment. This could result in serious injury or death.

Seat belt tensioners




Warning! Never use an ohmmeter or similar tool to test airbags or seat belt tensioners. Disconnect airbags or seat belt tensioners before testing them. Failure to do so may result in accidental deployment. This could result in serious injury or death.

There are two seat belt tensioners in the car. The seat belt tensioners are located in the B posts on the passenger and driver's sides. They contain an explosive charge which tensions the seat belts when deployed. The seat belt tensioners are separated from each other electrically. This means that each seat belt tensioner has a separate individual power supply and ground from the control module. Information on whether the seat belt is engaged or not is sent from the seat belt buckle to the Supplemental Restraint System Module (SRS).

The seat belt tensioner tensions the seat belt to reduce the forward movement of the body. This also reduces the forces on the chest from the airbag and seat belt.

The supplemental restraint system module (SRS) determines whether to deploy the seat belt tensioners based on whether the seat belts are being used. The seat belt tensioner will not be activated if the seat belt is not engaged. However if the control module does not receive a value or reads off incorrect data for the front seat belt buckles, the seat belt tensioners will be activated and the air bag will be deployed. The deployment level of the airbag is the same as if the seatbelt is not used.

The seat belt tensioner consists of a pyrotechnical charge and a cylinder with a piston. The piston is connected to a steel cable which is secured to the seat belt reel. When the control module activates the seat belt tensioner the piston is forced downwards by the expanding gas. The piston pulls in the steel cable which reels in the belt.

Warning! Never use an ohmmeter or similar tool to test airbags or seat belt tensioners. Disconnect airbags or seat belt tensioners before testing them. Failure to do so may result in accidental deployment. This could result in serious injury or death.

Inflatable curtain (model year 2001-)




Warning! Never use an ohmmeter or similar tool to test airbags or seat belt tensioners. Disconnect airbags or seat belt tensioners before testing them. Failure to do so may result in accidental deployment. This could result in serious injury or death.

Inflatable curtains were introduced from and including model year 2001.

There are two inflatable curtains connected to the Supplemental Restraint System Module (SRS). Their connectors are electrically separated from each other.

The inflatable curtains are located in the roof between the A and C posts. The inflatable curtains have only one ignition component. The Supplemental Restraint System Module (SRS) deploys the inflatable curtains individually, depending on the signals from the side impact sensors. The inflatable curtains normally deploy on the side of the impact. For further information, see Deployment of side impact protection (SIPS) . The task of the inflatable curtains is to protect the head and the upper body in the event of a side impact.

Inflatable curtains use a smaller pyrotechnical charge. This is connected to a container filled with argon and helium. When the control module deploys the inflatable curtains, the pyrotechnical charge heats up the container which then bursts. The expanding gases inflate the curtains which drop down and cover the side windows and the B-post. The inflatable curtain is inflated for approximately 3 seconds after deployment.

Warning! Never use an ohmmeter or similar tool to test airbags or seat belt tensioners. Disconnect airbags or seat belt tensioners before testing them. Failure to do so may result in accidental deployment. This could result in serious injury or death.

SRS indication




The Supplemental Restraint System Module (SRS) checks the different components of the system twice per second. A diagnostic trouble code (DTC) is stored and the SRS indicator lamp lights if the same fault is detected 5 times over a period of approximately 2.5 seconds.

SRS indication is through a warning lamp in the combined instrument panel. The SRS (supplemental restraint system) indicator lamp lights at ignition on while the system is checked. The check takes approximately 5 seconds. If no faults are registered by the control module, either internally or from the sensors, wiring or igniters, a signal is transmitted to the combined instrument panel confirming that the SRS indicator lamp can be switched off. If a fault was found in the Supplemental Restraint System Module (SRS), the SRS indicator lamp remains lit.

The memory in the Supplemental Restraint System Module (SRS) is EEPROM. This retains information about diagnostic trouble codes (DTCs) even after the power supply to the control module has been cut.

Note! Never take a resistance reading across the airbags or seat belt tensioners if a diagnostic trouble code (DTC) is stored for too high or low igniter resistance. Special tools with the same resistance as the airbag or seat belt tensioner must be used for fault-tracing.

Seat belt buckle




The two front seat belt buckles contain a magnetic sensor, called a hall sensor. The hall sensor detects whether the belt is engaged in the seat belt buckle or not and indicates this to the supplemental restraint system module (SRS). This data is used to set the activation level of the airbags and to determine whether or not the seat belt tensioners need to be activated. If a fault is detected in the seat belt buckles or in the terminal for the seat belt buckles, the activation level of both the driver and passenger airbags is set as if the occupant is not wearing a seat belt. The seat belt tensioner will still function as if a someone was using the seatbelt. The system strives to provide maximum protection for the traveller.

Note! In the event of a fault either in the hall sensor or wiring a diagnostic trouble code (DTC) is stored locally in the Supplemental Restraint System Module (SRS). The diagnostic trouble code (DTC) can be read off using VIDA.

Deploying airbags / seat belt tensioners

The collision safety system is extremely advanced. It is able to adapt airbag deployment and the activation of the seat belt tensioners to suit the specific circumstances of a collision. In general it is extremely unlikely that all airbags and seat belt tensioners will be deployed in the same accident. It is possible that only one airbag or seat belt tensioners is deployed. This is determined by the supplemental restraint system module (SRS) based on the forces that occur during the collision.
For example a collision at headlamp height can push in the entire upper front section, but the SRS (supplemental restraint system) will still only deploy the seat belt tensioners. This is because the impact is “softer” than if the collision force had been through the chassis where more force would be transferred to the Supplemental Restraint System Module (SRS).

1 stage deployment
On model year 1996-2000 cars, the front airbags had 1 stage deployment.
When the supplemental restraint system (SRS) module deploys the airbags, they are deployed at the same rate.

2 stage deployment
From model year 2001, the front airbags have 2 stage deployment.
If the Supplemental Restraint System Module (SRS) deploys the front airbags, both stages will always be activated. By varying the time between the two deployment phases, the deployment of the airbag is more gentle for a low speed collision.

Deployment of side impact protection (SIPS)

The deployment of the side impact protection (SIPS) bag and inflatable curtains is achieved by co-operation between the side impact sensors and the Supplemental Restraint System Module (SRS).
The side impact sensors are located on the B and C posts, behind the front and rear doors respectively on both sides. The sensors measure the lateral acceleration of the vehicle. The signals are analysed. If the calculated impact exceeds a certain level the side impact sensors checks with the Supplemental Restraint System Module (SRS) whether deployment of one or more side impact protection (SIPS) bags or inflatable curtains is required. If the Supplemental Restraint System Module (SRS) determines that the impact has reached that level, the side impact sensors deploy the side impact protection (SIPS) bags and / or inflatable curtains.

The Supplemental Restraint System Module (SRS) can register multiple collisions. The Supplemental Restraint System Module (SRS) determines what action should be taken in the event of each “individual” collision depending on the impact of each collision. The Supplemental Restraint System Module (SRS) and the side impact sensors can therefore deploy one airbag first and then deploy another if it is necessary.
Example:

*If there is a collision directly from the side at driver's door height, the side airbag and the inflatable curtain on the driver's side may be deployed depending on the force of impact
*If a collision from the side occurs at the joint of the right rear door and cargo compartment, the right inflatable curtain may deploy depending on the force of impact
*A collision diagonally from the rear which first hits the rear door and then "continues forward", can deploy both the inflatable curtain and the side airbag even if the impact was first registered at the C post.

Deployment levels for airbags and seat belt tensioners (model years 1996-2000)

The table below shows how the SRS system reacts in the event of a frontal impact.

Note! The deployment of the driver and passenger airbags is calculated individually.

N.a.v. de reactie van Wouter ben ik blij dat er zoveel veiligheid in de Volvo verwerkt is. Alleen jammer dat er ook 'bugs' kunnen zitten in electronica.

De witte stekker onder de bestuurdersstoel die ik in mijn vorige reactie meldde (soort witte DIN stekker met een schroefvergrendeling om ergens anders op aan te sluiten) lijkt er niets mee te maken te hebben. Ik zie geen enkele aansluiting waar 'ie op zou kunnen passen. Iemand een flauw idee wat dit voor iets is?

Voor het controlelampje zit er niets anders op dan uit te laten lezen en resetten.
Ik meld nog wel hoe dat afloopt.

Het bleek erg simpel te zijn: een stekkertje onder de linker stoel maakte geen contact, hoewel het er normaal uit zag. Goed vast klikken loste de storing op. Resetten is hier inderdaad niet aan de orde.
De vraag blijft natuurlijk hoe dit kan gebeuren?

ik heb gisteren het plastic van de b-stijlen vervangen, nu blijft het airbag lampje ook branden.

zie geen loszittende stekkers, ben hier ook niet aangekomen. Heb wel de gordels los moeten maken onderaan de stoel, deze zit gewoon weer vast.
in de b-stijlen heb ik wel sensoren zien zitten en die heb ik mooi laten zitten uiteraard..
Zoals ik uit het boekje begrijp zit er bij het bevestigingspunt van de gordels, onder/zijkant stoelen, een mechanische sensor.
Wellicht heb ik de fout gemaakt de auto te starten zonder dat de gordel onder weer vast zat?

Anyway, klopt het nu dat zolang het lampje brandt er een probleem is of blijft ie sowieso branden en moet deze altijd gereset worden?

De sensoren in de b-stijlen kon ik overigens niet terug vinden in het boekje waar die voor dienen, maar ik heb dan ook een boekje van een ouder model :sleeping blijkbaar side-impact sensoren zoals uit Wouters verhaal te lezen

"Diagnostic trouble codes (DTCs) cannot be erased until they have been read off at least once and the cause of the fault has been remedied"

haast, haast, weer niet goed gelezen (A)

nu vermoed ik dat de sensoren in de b-stijlen de foutmelding genereren, maar ik snap die sensoren niet helemaal. Aan een kant merkte ik dat ie nogal los zat, de sensor heeft een soort staafje dat ergens in gaat en dit was zo heen en weer te schuiven.. klopt dat wel of hoort deze vast te klikken o.i.d. ?

In de B-stijl zitten je gordelhaspels, met daaronder de gordelspanner.
De gordel spanner is met een zelfde groene stekker aangesloten als de airbag.
Want dit is ook een springlading welke afgaat bij een botsing, waardoor de gordel ongeveer 20-30 cm naar binnen wordt getrokken en locked.

Deze lading en verbinding wordt ook elke keer gecontroleerd.

De side cushion is een stand-alone systeem, wat afgaat als de deur bij een ongeluk naar binnen komt en de sensor indrukt. In de zijkant van stoel wordt dan het kussen opgeblazen.

Je moet de fout code natuurlijk wel wissen, de SRS control unit houdt het bericht vast.

Als na het wissen de fout weer direct terugkomt, is de fout er nog niet uit.

Vraag : Wat voor foutcode geeft deze dan?

Bericht door johnny » ma 04 okt 2010, 13:07

Gisteren sprong tijdens het rijden op de snelweg opeens het airbag lampje aan op de console. Vanmorgen brande die ook de hele rit. Weet iemand waar ik moet beginnen te kijken? kan dit zekeringwerk zijn, of moet ik toch hiervoor naar de garage?

Ik heb er geen verstand van, maar zou in zo'n geval wel verstandig zijn en het bij de garage laten controleren.
Veiligheid is toch wel belangrijk vind ik (H)

Voor deze klacht moet je de auto laten uitlezen.

Waarschijnlijk een verbindings probleem, van de airbags of gordelspanners.

Voor de duidelijkheid het lampje gaat niet vanzelf uit, de fout moet opgelost zijn en met diagnose apparaat uit het geheugen gewist worden.

Als je in de buurt van Schiphol woont, kan ik je helpen.

Groetjes Wouter

ik woon niet in de buurt van schiphol, maar het is wel in de buurt van mijn woon-werk traject (utrecht - amsterdam sloterdijk); dat leg ik meestal per trein af maar als je mij een keer wil helpen met uitlezen ga ik natuurlijk met de auto :-). zal een pm versturen!

Ik heb 't vandaag bij de garage laten uitlezen; sporadische fout op de zijbag van de passagier. De garage heeft (tegen de voorschriften in vziw) het controlelampje weer gereset dus ik twijfel nu of ik het hierbij laat en er dan van uit ga dat het een incident was; iets dat nu wel werkt is toch moeilijk op een defect te betrappen, dus dat wordt een dure controle om te ontdekken waarom hij het ooit niet deed lijkt mij. wat vinden jullie?

Verder kwam bij het uitlezen ook een ander probleem naar voren met de gloeibougies/relais. ik vraag me af wat ik daarmee moet doen: ondanks het koude weer start de auto altijd in 1x direct. kunnen die dingen dan wel echt kapot zijn of zit het MMS me voor de gek te houden?

Als de verbinding niet goed is, komt de fout weer opnieuw terug en zul moeten troubleshooten.

Wat betreft het gloeirelais:

Condition

The glow plug relay has an internal diagnostic which checks both the glow plugs and the internal circuits. The engine control module (ECM) checks the control signal cable to the glow plug relay. The engine control module (ECM) checks for any internal faults in the glow plug relay.
Diagnostic trouble code (DTC) ECM-1816 is stored (signal too low or too high) if the engine control module (ECM) registers a fault in the control signal cable for the glow plug relay.


Heb je een voltmeter?
Sluit deze aan op de accu.
Zet verlichting en alle stroomgebruikers uit.
Zet het contact op I en lees de spanning af op de voltmeter.
Zet het contact op II niet starten en de spanning af op de voltmeter, deze moet wat gezakt zijn.
Contact weer op I en spanning moet weer ongeveer terug zijn als eerder gemeten.

Het gloeisysteem is een verwarming en zal de spanning wat omlaag brengen als deze is ingeschakeld en de motor loopt niet.

thanks wouter; wat betreft die airbag, dat realiseer ik me en als het terug komt laat ik er alsnog naar kijken.

die gloeiboegies/relais; als daar een probleem mee was (heb hier niet even een voltmeter), zou ik dat dan niet gemerkt moeten hebben met het koude weer? ik bedoel hij heeft nog geen enkele moeite getoond om te starten met deze kou.
