DAYTIME LIGHT RELAY CIRCUIT

DAYTIME LIGHT RELAY CIRCUIT

Description

INFOID:0000000006823259

The BCM sends a daytime light request to the IPDM E/R via the CAN communication lines. The power flows

backward through fuse 45 located in IPDM E/R to daytime light relay 1 and LH high beam lamp to IPDM E/R,

through the high beam fuses, through the RH high beam lamp and on to ground. The high beam lamps are

wired in series which causes them to illuminate at a reduced intensity.

Diagnosis Procedure

INFOID:0000000006823260

FRONT FOG LAMP CIRCUIT

FRONT FOG LAMP CIRCUIT

Description

INFOID:0000000006247660

The IPDM E/R (intelligent power distribution module engine room) controls the front fog lamp relay based on

inputs from the BCM via the CAN communication lines. When the front fog lamp relay is energized, power

flows from the front fog lamp relay in the IPDM E/R to the front fog lamps.
