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.
3.DEF
NOTESOnly deal with this fault when it is present.
Switch off the ignition and wait for the diagnostic tool message (maximum time 8minutes) Communication lost
with computer: EDC16 C36, check the tool connection and computer power supply before switching the
ignition back on.
Switch on the ignition again and check if the fault is still present.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition until the end of the power-latch phase, and carry out a road test
followed by a check using the diagnostic tool.
