IMPACT DETECTED SIGNAL
NOTESFault finding procedure application conditions:
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.
As soon as the injection computer receives this signal, engine operation is inhibited
and the level 2 warning light is lit.
Use bornier Ele. 1681 for all operations 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 and wait 30 seconds,
– wait for the engine immobiliser indicator light to flash,
– switch on the ignition,
If the fault does not reappear, end of fault finding procedure.
If the fault recurs, carry out fault finding on the AIRBAG computer.
If the vehicle has not been involved in an accident, carry out fault finding on the Airbag computer.
AFTER REPAIRDeal with any faults.
Carry out a road test, then check with the diagnostic tool.

With the ignition on and the camshaft sensor connected:
Use a voltmeter to measure the voltage between tracks 1 and 3 of the camshaft sensor:
The voltage displayed should be equal to the battery voltage 0.08 V)
if the voltage is outside permitted tolerance values, take the measurement again with the camshaft sensor
disconnected.
If the voltage is still outside the permitted tolerance values with the sensor disconnected, check the continuity and
absence of interference resistance on the following connection:
