WIRING - SYSTEM CIRCUIT DIAGRAM 71-71

Description:

• Front fog lamp
Operating condition: the parking light must be turned on.

The current of the battery flows from fuse F18 in the engine compartment fuse box,
and provides power supply to pin 1 and pin 3 of the front fog lamp relay R7; When
turning on the front fog lamp switch in the combination switch, the pin 7 is grounded
to earth, the current outputs from pin 8 connected to the pin E9 of the body control
module connector C036, providing the open signal for the front fog lamp switch;
The current then outputs from the body control module C035 pin D16 to the front
fog lamp relay R7 pin 2,the coil generates a magnetic field and the contact is closed;
When the contact of the front fog lamp relay R7 is closed, the current flows from
the pin 5 to the front fog lamp pin 1, through the filament and and grounded via pin
2. Then the front fog lamp starts to work.

• Rear fog lamp
Operating condition: the parking light must be turned on, and for the front fog lamp
and the headlamp, at least one of them must be turned on.

When switched on, pin 7 of the rear fog lamp switch is grounded, and pin 9 signal
output to pin 10 of BCM C036, providing the signal that the rear fog lamp is on.
The current flows from the body control module connector C034 pin C8 to the rear
fog lamp pin 1, through the filament and pin 2 to earth. Then the rear fog lamp
starts to work.
