Description
The IPDM E/R (intelligent power distribution module engine room) controls the headlamp high relay based on inputs from the BCM over the CAN communication lines. When the headlamp high relay is energized, power flows through fuses 48 and 49, located in the IPDM E/R. Power then flows to the front combination lamps to the headlamp high beam.
Component Function Check
1.CHECK HEADLAMP (HI) OPERATION
WITHOUT CONSULT
NOTE: HI/LO is repeated 1 second each when using the IPDM E/R auto active test.
CONSULT
HI : Headlamp switches to the high beam.
OFF : Headlamp OFF
Diagnosis Procedure
1.CHECK HEADLAMP (HI) FUSES
2.CHECK HEADLAMP (HI) OUTPUT VOLTAGE
CONSULT ACTIVE TEST
3.CHECK HEADLAMP (HI) CIRCUIT FOR OPEN
4.CHECK FRONT COMBINATION LAMP (HI) GROUND CIRCUIT
Check continuity between the front combination lamp harness connector terminal and ground.
5.CHECK CONTINUITY BETWEEN FRONT COMBINATION LAMP RH (HI) AND DAYTIME LIGHT RELAY
6.CHECK DAYTIME LIGHT RELAY GROUND CIRCUIT
Check continuity between daytime light relay harness connector and ground.
7.CHECK DAYTIME LIGHT RELAY FUSE
8.CHECK DAYTIME LIGHT RELAY CIRCUIT FOR OPEN
9.CHECK DAYTIME LIGHT RELAY
Check daytime light relay
