Warning! Under no circumstances use an ohmmeter or other live measuring instrument to take readings on a disconnected, non-deployed, pyrotechnical airbag. This could deploy the airbag!
Caution! Do not touch the terminal pins in the supplemental restraint system module (SRS). There is a risk of static discharge. This could damage the supplemental restraint system module (SRS).
- Check cables and terminals if the diagnostic trouble code (DTC) is intermittent. Remedy as necessary and select alternative 1 at the bottom
- If the diagnostic trouble code (DTC) is permanent, continue fault-tracing
- Switch off the ignition. Wait 10 seconds
- Disconnect the connector from driver's airbag stage 1
- Connect a special tool to the connector (to the ignition cable). To carry out this procedure, use: 951 1506 Test dummy 951 1506 Test Dummy
Note! The special tool must be checked and fault-free. If the special tool is faulty, the diagnostic readings will be incorrect. This will make fault-tracing harder.
- Switch on the ignition. Wait 10 seconds.
Read diagnostic trouble codes by clicking the VCT2000 symbol.
If the diagnostic trouble code (DTC) changes status from permanent to intermittent fault, replace the driver's airbag and select alternative 1 at the bottom.
If the diagnostic trouble code (DTC) is still permanent, select alternative 2 at the bottom.

Checking the component and wiring
- Switch off the ignition. Wait 10 seconds
- Disconnect the special tool from the connector
- Disconnect the contact reel connector
- Disconnect the connectors from the supplemental restraint system module (SRS).
Warning! Under no circumstances use an ohmmeter or other live measuring instrument to take readings on a disconnected, non-deployed, pyrotechnical airbag. This could deploy the airbag!
Caution! Do not touch the terminal pins in the supplemental restraint system module (SRS). There is a risk of static discharge. This could damage the supplemental restraint system module (SRS).
Check the connectors for the driver's airbag, the contact reel and the supplemental restraint system module (SRS). Check for contact resistance. Check for oxidation. Check for loose connections:
Remedy as necessary.
Check the SRS ignition cables between supplemental restraint system module (SRS) and the contact reel connector. Check for an open-circuit.
Check the cable between:
- Supplemental restraint system module (SRS) terminal #B6 and contact reel connector terminal #3
- Supplemental restraint system module (SRS) terminal #B7 and contact reel connector terminal #4.
Remedy as necessary.
Connect the contact reel connector. Check the SRS ignition cables between supplemental restraint system module (SRS) and the connector for the driver's airbag stage 1. Check for an open-circuit.
Check the cable between:
- The supplemental restraint system module (SRS) terminal #B6 and the connector for the driver's airbag stage 1 terminal #1
- The supplemental restraint system module (SRS) terminal #B7 and the connector for the driver's airbag stage 1 terminal #2.
Remedy as necessary.

Hint: After carrying out the repair check that the fault has been remedied.
- Switch off the ignition. Wait 10 seconds
- Disconnect the battery negative lead
- Reinstall the connectors, components etc.
- Ignition on
- Connect the battery negative lead. Wait 10 seconds.
Warning! There must not be anyone inside the passenger compartment when the battery is connected.
Read diagnostic trouble codes by clicking the VCT2000 symbol.
If the fault is intermittent, the fault has been remedied.

The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.
Do you want to exit fault-tracing?
Yes - Exit fault-tracing
No - Attempt New Test
