HEADLAMP (HI) CIRCUIT
DescriptionINFOID:0000000012432804
The IPDM E/R (intelligent power distribution modul e engine room) controls the headlamp high relay based on
inputs from the BCM via 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 lamp LH
and RH high beams.
Component Function CheckINFOID:0000000012432805

Regarding Wiring Diagram information, refer to EXL-25, "Wiring Diagram - For USA" or EXL-31, "Wiring Dia-
gram - For Canada".
1.CHECK HEADLAMP (HI) FUSES
1. Turn the ignition switch OFF.
2. Check that the following fuses are not blown:
Is the fuse blown?
YES >> Replace the blown fuse after repairing the affected circuit.

2.CHECK HIGH BEAM BULB
Check the applicable high beam bulb to be sure the proper bulb standard is in use and the bulb is not open.
Is the bulb OK?
YES >> GO TO 3.
NO >> Replace the bulb.
3.CHECK HEADLAMP (HI) OUTPUT VOLTAGE
1. Turn the ignition switch OFF.
2. Disconnect the front combination lamp connector E25 or E26.
3. Turn the ignition switch ON.
4. Turn the high beam headlamps ON.
5. With the high beam headlamps ON, check the vo ltage between the combination lamp connector and
ground. HI : Headlamp switches to the high beam.
OFF : Headlamp OFF

flows through fuses 40 and 41, located in the IPDM E/R.
(Without daytime running light system) power then flow s to the front combination lamp LH and RH low beams.
(With daytime running light system) power then flows to the front combination lamp LH low beam and the day-
time running light relay 2 which becomes energized and t hen power is sent to the front combination lamp RH
low beam.
