HEADLAMP (XENON)
HEADLAMP (XENON) : DescriptionINFOID:0000000001527565
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 34 and 35, located in the IPDM E/R. Power then flows to the front combination lamps to
the headlamp high beam.
HEADLAMP (XENON) : Component Function CheckINFOID:0000000001527566
1.CHECK HEADLAMP (HI) OPERATION
WITHOUT CONSULT-III
1. Start IPDM E/R auto active test. Refer to XX-XX, "*****"
.
2. Check that the headlamp switches to the high beam.
NOTE:
HI/LO is repeated 1 second each when using the IPDM E/R auto active test.
CONSULT-III
1. Select "EXTERNAL LAMP" of IPDM E/R active test item.
2. With operating the test items, check that the headlamp switches to the high beam.
Does the headlamp switch to the high beam?
