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 41 and 42, 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
Is the inspection result normal? YES >> Headlamp (HI) circuit is normal.
NO >> Refer to EXL-88, "Diagnosis Procedure".
Diagnosis Procedure
Regarding Wiring Diagram information, refer to EXL-33, "Wiring Diagram".
1.Check headlamp (HI) Fuses
Is the fuse blown? YES >> Replace the fuse after repairing the affected circuit.
NO >> GO TO 2.
2.Check headlamp (HI) output voltage
Consult active test
Is the inspection result normal? Yes >> go to 4.
No >> go to 3.
3.Check headlamp (hi) circuit for open
Is the inspection result normal? Yes >> replace ipdm e/r. Refer to pcs-30, "removal and installation" (with intelligent key system) or pcs-58, "removal and installation" (without intelligent key system).
No >> repair or replace the harness or connector.
4.Check front combination lamp (hi) ground circuit
Check continuity between the front combination lamp harness connector terminal and ground.
