NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after the engine has been started.
Special notes:
If CC.1, CC, or 1.DEF is present, the level 2 warning light is lit.
If CO is present the level 1 warning light is lit.
If CO is still present, the OBD warning light will come on after three consecutive driving
cycles (starting + 5 seconds + switching off the ignition and waiting for 1 minute).
If the fault is present, the injection on cylinder 3 is disabled.
Use bornier Ele. 1681 or Ele. 1590 for any operation on the injection computer
connectors.
WARNING
This fault may appear if the wiring harness has been damaged.

NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after several starting attempts, or with the engine running.
Special notes:
Computer operating voltage: 9 V < operating voltage < 16 V.
Battery voltage that is too low can cause the level 1 fault warning light to come on
thereby causing other faults to appear.
Use bornier Ele. 1681 or Ele. 1590 for any operation on the injection computer
connectors.
Check continuity and make sure there is no interference resistance on the following connection:
injection computer black 32-track connector A, track D1 track 1 UPC black connector
Repair if necessary.
Check fuse F5D (5A) located on the UPC.
Check the condition of the injection control unit supply relay (50A) located on the relay plate in the engine
connection unit under the Protection and Switching Unit (no false contacts, or oxidation on the relay mounting
clips).
Repair if necessary.
If the fault does not recur, start the engine and wait 1 min.
Carry out a road test and check the system faults.

The fault is declared present after the engine is started or following a road test.
Check the conformity of the fuel used by applying test 10 Diesel fuel conformity check.
Check the sealing of the tank and low pressure circuit by applying test 2 Low pressure circuit check.
A) Make sure the water in diesel fuel detection sensor is properly connected.
–If not, clear the fault,
–Carry out a road test (speed > 12 mph (20 km/h) and engine speed > 1200 rpm) for more than 30 seconds.
–If the fault does not recur, end the fault finding procedure.
–If the fault does recur, go to step C.
B) If the water detection sensor is absent:
–Insulate the electrical connector not connected to the vehicle (risk of dampness, oxidation, and erratic
appearance of faults).
Check that the configuration reading LC065 Water detected in the diesel is NONE.
If LC065 is WITH, run command RZ005 Programming to reinitialise the vehicle configurations.
–Clear the faults.

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:
