Description
The ipdm e/r (intelligent power distribution module engine room) controls the headlamp low relay based on inputs from the bcm over the can communication lines. When the headlamp low relay is energized, power flows through fuses 43 and 44, located in the ipdm e/r. Power then flows to the front combination lamps to the headlamp low beam.
Component function check
1.Check headlamp (lo) operation
Without consult
Note:
HI/LO is repeated 1 second each when using the IPDM E/R auto active test.
Consult
Lo : headlamp on
Off : headlamp off
Is the inspection result normal? YES >> Headlamp (LO) is normal.
NO >> Refer to EXL-90, "Diagnosis Procedure".
