NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after the engine is started or following a road test.
Special notes:
The cruise control/speed limiter function is inhibited.
Use bornier Elé. 1681 or Elé. 1590 for any operation on the injection computer
connectors.
WARNING
This fault may appear if the wiring harness has been damaged.
Follow the procedure described in the Wiring Check in the Introduction.
This check enables the condition and the conformity of the engine wiring harness to be checked.
If the fault is declared present, refer to the section of the conformity check on the Cruise control/Speed limiter,
and to the interpretation of statuses:
ET042 Cruise control/speed limiter.
ET415 Deactivation of cruise control/speed limiter.
ET703: Cruise control/speed limiter buttons
Check that by pressing the buttons the statuses change and that, with the ignition switched on, all the values are
correct.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

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.
As soon as the injection computer receives this signal:
–engine operation is prohibited,
–the level 2 warning light is lit.
Use bornier Ele. 1681 or Ele. 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 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.
If the vehicle has not been involved in an accident:
Run fault finding on the AIRBAG computer
AFTER REPAIRDeal with any faults.
