Checkwhetherthe faultappearsagain. a) If the fault does not appear again, replace the passenger's airbag unit. b) If the fault appears again, check the wiring harnessfor pinches and chafing damage. c) If no fault is found on the wiring harness, replace the triggering unit. Note Signal not plausible. This fault path is checked only during the self-test of the triggering unit, i.e. updating of the fault during the cyclical tests does not take place. If the fault memory is cleared, the ignition must be switched off, the igni- tion key removed and the ignition switched on again in order to check the fault path. Only in this way is another self-test carried out. Test point 3 Supplyvoltage 1. Inspectthe battery and generator. Fault code 03 2. Inspectthe plug connectionon the triggering unit for corrosion.
