2.DEFNOTESUse the Wiring Diagram Technical Notes for the vehicle.
Reminder of computer operating voltage: 6 V < operating voltage < 16.5 V
Using a voltmeter, take a reading of the battery voltage at its terminals.
– Compare the voltage obtained with the value displayed on the diagnostic tool PR074 Battery voltage.
If it there is no difference (less than 1 V):
Recharge and test the battery and replace it if it is defective.
Next check the charge circuit.
If there is a difference (greater than 1 V):
– Check the tightness and the condition of the battery terminals.
– Using the appropriate wiring diagram:
Check the continuity and absence of interference resistance on the following connections:
– Connection code 3FB between components 597 and 120.
– Connection code AP29 between components 597 and 120.
– Connection code NT between components NT and 120.
(Check the four NT connections)
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.

Start the engine and re-establish dialogue.
This fault may be linked to a write error following disconnection of the battery when the computer was in the
process of writing to the EEPROM phase (computer memory).
If this is the case, loading a new calibration will remove the fault.
If a more recent calibration is available, load this calibration on to the computer.
If the fault is still present:
– use the command RZ034 Computer memory,
– Switch off the ignition and wait for the computer dialogue lost message,
– switch on the ignition again,
– define the injector codes using the control SC002 Enter injector codes.
