NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present under + after ignition feed.
Special notes:
As soon as the injection computer receives this signal:
– engine operation is prohibited,
the level 2 warning light is lit.
The fault appears when the injection computer receives a frontal impact signal from the Airbag computer via the
multiplex network.
Do not deal with this fault.
If the vehicle has been involved in an accident:
Carry out any necessary repairs,
– clear the fault,
– switch off the ignition,
–wait for 1 minute,
– switch on the ignition.
If the fault does not reappear, end of fault finding procedure.
If the fault recurs, run fault finding on the AIRBAG computer.
If the vehicle has not been involved in an accident:
Run fault finding on the AIRBAG computer (see 88C, Airbag and pretensioner).
