Check the condition and connection of the connector of the reverse gear switch component code 155, the
multifunction switch component code 485 and the UPC connector MN component code 1337.
If the connector is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the connector, otherwise replace the connector.
With the ignition on and reverse gear engaged, check for + 12 V on connection codes H66P and AP11 of
Protection and Switching Unit connector MN, component code 1337.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check the insulation, continuity and the absence of interference resistance on the following connections:
–AP11 between components 1337 and 485,
–H66P between components 1337 and 485.
If the connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, contact the Techline.
AFTER REPAIRRepeat the conformity check from the start.

With the engine running, main beam
headlights and heated rear screen on,
measure the voltage between the B+
battery feed and B+ alternator feed
Check the condition of all the wires connecting the
battery, alternator and starter and that all of their
terminals are correctly tightened. Is the voltage > 0.7 V?
Repair any damaged wires and terminals. If the
connection is faulty and if there is a repair
procedure (see Technical Note 6015A Electrical
wiring repair, Wiring: Precautions for repair),
