STOREDIMPACT DETECTED SIGNAL
1.DEF: Impact stored by the injection computer
NOTESConditions for applying the fault finding procedure to stored faults:
Only apply the interpretation of this fault if the fault is present and the vehicle will not
start.
Special notes:
The fault appears when the injection computer receives a frontal impact signal from
the Airbag computer via the multiplex network.
As soon as the injection computer receives this signal:
– engine operation is prohibited,
– the level 2 warning light is lit.
Use bornier Elé.1681 or Elé.1590 for any operation on the injection computer
connectors.
If the vehicle has been involved in an accident:
Carry out any necessary repairs,
– clear the fault,
– switch off the ignition,
–wait 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).
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.
