Check the + 12 V APC on connection BPT of component 1415.
If the connector is faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector; otherwise, replace the wiring.
If the + 12 V feed is not correct, check the insulation, continuity and the absence of interference resistance
of the following connection:
●Connection code BPT between components 645 and 1415.
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.
If the + 12 V feed is not correct for vehicles manufactured after June 2005, check the insulation, continuity and
the absence of interference resistance on the following connection:
●Connection code BPT between component 645 and fuse F5F (7.5A) (on the Protection and Switching
Unit).
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,

Check for earth on connection MZ of component 139 or on connection MAQ of component 138.
If the connector is faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector; otherwise, replace the wiring.
Check the insulation, continuity and the absence of interference resistance on the following connections:
●Connection code 87A between components 645 and 139.
●Connection code 87B between components 645 and 138.
If the connection or 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.
