Check the connection and condition of the passenger compartment fuse and relay box, the gear lever display,
the steering column top control module, the additional heater relay 1 and 2, the diagnostic socket, the
parking distance control ECU, the right and left-hand rear electric window switch, the radio, the electric
door mirror control, the front and rear electric window locking controls and the passenger electric window
switch, component codes 260, 1129, 1546, 1067, 1068, 225, 1222, 130, 131, 261, 134, 135, 1511, 1512
and 133.
Check for a voltage on connection AP43 to the connectors for the passenger compartment fuse and relay box,
the gear lever display, the steering column top control module, the additional heater relay 1 and 2, the
diagnostic socket, the parking distance control ECU, the right and left-hand rear electric window switch,
the radio, the electric door mirror control, the front and rear electric window locking controls, the
passenger electric window switch, component codes 260, 1129, 1546, 1067, 1068, 225, 1222, 130, 131, 261,
134, 135, 1511, 1512 and 133.
If the connection or connections are faulty and if 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:
–AP31 between components 1337 and 997,
–AP11 between components 1337, 485, 155 and 1109,
–APCB between components 1337 and 645,
–AP15 between components 1337 and 1088,
–AP44 between components 1337, 756 and 1232,
–AP43 between components 1337, 260, 1129, 1546, 1067, 1068, 225, 1222, 130, 131, 261, 134, 135, 1511, 1512
and 133.
If the connections are faulty and if there is a repair procedure (see Technical Note 6015A, Electrical wiring
repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check the connection and condition of the Protection and Switching Unit, component code 1337.
If the connector is faulty and if there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the connector, otherwise replace the connector.
If the fault is still present, contact the Techline.
AFTER REPAIRErase the faults from the computer memory, switch the + after ignition supply off and
back on again and run another check using the diagnostic tool.
