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:
If the fault is present, engine performance is reduced and engine instabilities may
occur.
Priority when dealing with a number of faults:
Deal with fault DF040 Cylinder 1 injector circuit first, if it is present or stored.
Check that the IMA code of injector no. 1 has been entered correctly and that it matches the code marked on the
corresponding injector.
Enter the code to the unprogrammed/incorrectly programmed injector, if necessary.
Refer to the interpretation of commands, SC002 Entering injector codes.
Check the engine compression.
Repair if necessary.
Check the valve clearance and adjust if necessary.
When dealing with several combustion misfire faults, check the conformity of the fuel by applying test 10 Diesel

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:

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.
