STOREDIMPACT DETECTED SIGNAL
1.DEF : Impact stored by the injection computer
NOTESConditions for applying the fault finding procedure to stored faults:
Only apply the procedure if the fault is present and if the vehicle does not start.
Special notes:
The fault appears when the injection computer receives a frontal impact signal from the
Airbag computer via the multiplex network.

connectors.
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 recur, end the fault finding procedure.
If the fault recurs, carry out fault finding on the AIRBAG computer.
