REAR FOG LAMP CIRCUIT

Description

INFOID:0000000001527571

The BCM (Body Control Module) controls power to the rear fog lamps based on inputs from the lighting switch
(combination switch). The BCM sends a request (via CAN communication lines) to the combination meter to
turn the rear fog lamp indicator light ON. 

Component Function Check

INFOID:0000000001527572

1.

CHECK REAR FOG LAMP OPERATION

CONSULT-III

1.

Select "RR FOG LAMP" of BCM active test item.

2.

With test items operating, check that the rear fog lamps are turned ON.

Is the rear fog lamp turned ON?

YES

>> Rear fog lamp circuit is normal.

NO

>> Refer to 

EXL-43, "Diagnosis Procedure"

. 

Diagnosis Procedure

INFOID:0000000001527573

HATCHBACK

1.

CHECK BCM POWER AND GROUND SUPPLY

Verify BCM power and ground supply. Refer to 

BCS-30, "Diagnosis Procedure"

.

Does BCM have proper power and ground?

YES

>> GO TO 2

NO

>> Repair harness or connector.

2.

CHECK REAR FOG LAMP OUTPUT VOLTAGE

CONSULT-III

1.

Turn the ignition switch OFF.

2.

Disconnect the rear fog lamp connector B89 and rear combination lamp LH connector B80.

3.

Turn the ignition switch ON.

4.

Select "RR FOG LAMP" of BCM active test item.

5.

With RR FOG LAMP ON, check the voltage between the rear fog lamp connector B89 terminal 1, rear
combination lamp LH connector B80 terminal 2 and ground.

Is battery voltage present?

YES

>> GO TO 4

NO

>> GO TO 3

3.

CHECK REAR FOG LAMP OPEN CIRCUIT

1.

Turn the ignition switch OFF.

2.

Disconnect BCM connector M20.

3.

Check continuity between the BCM harness connector M20 (A) terminal 69 and the rear fog lamp harness
