Electric detonator 2 Short circuit to battery positive Short circuit to ground



Cars with passenger airbag


1. Make a note of the diagnostic trouble code and then clear it. Switch the ignition off and on again, wait for at least 40 seconds with the ignition switched on and check to see whether the diagnostic trouble code recurs. If it does, it is a permanent fault. Proceed to point 2.

If it does not, the fault is intermittent.

Leave the ignition switched on and turn the steereing wheel. Jiggle the connectors and wiring.

Do this to check for an open circuit/loose connections. Note whether the SRS lamp starts flashing again. If it does, check whether the diagnostic trouble code recurs.

2. Unscrew the steering wheel airbag and unplug the connector at the back of the airbag. Connect reference resistor 84 71 153 to the connector.


On cars with a passenger airbag, remove the glove box, unplug the connector on the underside of the passenger airbag and connect reference resistor 84 71 153 to the connector.

3. Switch on the ignition and clear the diagnostic trouble code. Switch the ignition off and on again, wait for at least 40 seconds and then check to see whether the diagnostic trouble code recurs.


If the diagnositc trouble code recurs, proceed to point 4.

If the diagnostic trouble code has gone, the fault is in the passenger airbag. Switch off the ignition and carry out a double check by connecting the airbag, switch on the ignition, wait for at least 40 seconds and then check to see whether the diagnostic trouble code recurs.

If it does, switch off the ignition and change the passenger airbag. Switch on the ignition and clear the diagnostic trouble code. Switch the ignition off and then on again. Wait for at least 40 seconds and then check to see whether the diagnostic trouble code recurs.

4. Switch off the ignition and remove the reference resistor from the passenger airbag's connector. Unplug the connector at the control module and connect a BOB to the connector on the wiring.


Switch on the ignition and connect a voltmeter to pin 8 and a good grounding point and to pin 6 and a good grounding point.

If neither of the readings shows battery voltage, proceed to point 5.

If either of the readings shows battery voltage, the fault is in the wiring between the passenger airbag's connector and the connector at the control module.

Investigate the cause and change the cable assembly.

Proceed to point 6.

5. Switch off the ignition and connect an ohmmeter to pin 8 and a good grounding point and to pin 6 and a good grounding point.


If either of the readings obtained shows a low resistance, the fault is in the wiring between the passenger airbag's connector and the connector at the control module.

Investigate the cause and change the cable assembly.

If both readings show high resistance, proceed to point 6.

6. Close the connector, switch on the ignition and clear the diagnostic trouble code. Switch off the ignition and switch it on again, wait for at least 40 seconds and then check to see whether the diagnostic trouble code recurs.


If the diagnositc trouble code recurs, proceed to .
