repair), repair the wiring, otherwise replace it.
–Check the battery charge.
–Check the charge circuit (see 80A, Battery).
–Check the tightness and the condition of the battery terminals.
–Check the computer earth connection NAP.
Use the universal bornier to check the insulation and continuity of the following connections:
–Connection code AP25 between components 756 and 1016,
–Connection code NAP on component 756.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
If the fault is still present, contact the Techline.
AFTER REPAIRClear the computer fault memory. Switch off the ignition.
