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 4 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.
Follow the procedure described in the Wiring Check in the Introduction.
This test enables the condition and the conformity of the engine wiring harness to be checked.

NOTESNone
With the ignition off, measure the voltage across the battery terminals.
If the voltage is less than 11.5 V, test the battery.
If the battery is faulty, replace the battery then test the charge circuit.
With the ignition on and the with the starter motor turning, measure the voltage between the battery terminals
If the voltage drops below 9.6 V, check the tightness and condition of the battery terminals.
Repair if necessary.
If the terminals are in good condition, test the battery.
If they are faulty, replace the battery.
If the starter is cranking the engine correctly, but the fault is still present,
–Check the continuity and absence of interference resistance of the following connections:
