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 jiggle the connectors and wiring to check for an open circuit/loose contact. Note whether the SRS lamp starts to flash again. If it does, check to see whether the diagnostic trouble code has recurred.

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. Unplug the connector at the electronic unit and connect a BOB. Unplug the connector behind the fuel gauge in the instrument unit, switch on the ignition and take a voltage reading across pin 1 and a good grounding point.


If the reading shows battery voltage, the fault is in the wiring between the instrument unit's connector and the control module's connector.

Investigate the cause and remedy the fault.

If the reading shows no voltage, proceed to point 4.

4. Change the bulb. Plug in the connectoros, switch on the ignition and clear the diagnostic toruble 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.


If the diagnostic trouble code has gone, the bulb was faulty.

If the diagnositc trouble code recurs, proceed to .
