DAYTIME LIGHT SYSTEM

Component Description

INFOID:0000000001527657

Part

Description

BCM

• Monitors lighting switch position, engine running status and parking brake status to 

determine if conditions are set for daytime light system operation.

• Requests the IPDM E/R via CAN communication lines to ground the daytime light 

relay coil. 

IPDM E/R

Controls ground to the daytime light relay coil based on requests from the BCM (via 
CAN communication lines).

Combination switch
(Lighting & turn signal switch)

Refer to 

XX-XX, "*****"

.

Combination meter

Monitors engine running status and forwards that information to the BCM via CAN 
communication lines.

INFOID:0000000001523237

System Description

INFOID:0000000001523238

The BCM (Body Control Module) controls front fog lamp operation based on input from the lighting switch
(combination switch). The BCM requests (via CAN communication lines) the IPDM E/R (Intelligent Power Dis-
tribution Module Engine Room) to activate the integrated front fog lamp relay and requests the combination
meter to illuminate the front fog lamp light.

FRONT FOG LAMP

Component Description

INFOID:0000000001523240

Part

Description

BCM

• Monitors the combination switch position.
• Requests the IPDM E/R (via CAN communication lines) to actuate the front fog lamp 

relay.

• Requests the combination meter (via CAN communication lines) to turn the front fog 

lamp indicator lamp ON.

IPDM E/R

Controls the integrated front fog lamp relay based on input from the BCM via the CAN 
communication lines.

Combination switch
(Lighting & turn signal switch)

Refer to 

BCS-9, "System Description"

.

Combination meter
(front fog lamp indicator lamp)

Controls the front fog lamp indicator during front fog lamp operation based on input 
from the BCM via the CAN communication lines.

System Diagram

INFOID:0000000001527666

System Description

INFOID:0000000001527667

The BCM (Body Control Module) controls rear fog lamp operation based on input from the lighting switch
(combination switch). When the lighting switch is in the 1st or 2nd position or auto position and the rear fog
lamp switch is ON, the BCM outputs battery voltage to the rear fog lamps. The BCM sends a request signal to
the combination meter via CAN communication lines to illuminate the rear fog lamp indicator.
