Concept of auto active test
• IPDM E/R starts the auto active test with the door
switch signals transmitted by BCM via CAN communica-
tion. Therefore, the CAN communication line between IPDM E/R and BCM is considered normal if the auto
active test starts successfully.
• The auto active test facilitates troubleshooting if any systems controlled by IPDM E/R cannot be operated.

CONSULT Function (IPDM E/R)INFOID:0000000009956488
CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentiall y causing a discharged battery and a no-start condition.

HEADLAMP (HI) CIRCUIT
DescriptionINFOID:0000000009463577
The IPDM E/R (intelligent power distribution modul e engine room) controls the headlamp high relay based on
inputs from the BCM over the CAN communication li nes. 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.
Component Function CheckINFOID:0000000009463578
1.CHECK HEADLAMP (HI) OPERATION
WITHOUT CONSULT
1. Start IPDM E/R auto active test. Refer to PCS-8, "Diagnosis Description"
.
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
1. Select EXTERNAL LAMP of IP DM E/R active test item.
2. While operating the test items, check t hat the headlamp switches to the high beam.
Is the inspection result normal?
YES >> Headlamp (HI) circuit is normal.
NO >> Refer to EXL-91, "Diagnosis Procedure"
.
Diagnosis ProcedureINFOID:0000000009463579
Regarding Wiring Diagram information, refer to EXL-27, "Wiring Diagram - Halogen" or EXL-33, "Wiring Dia-
gram - Xenon".
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 fuse after repairing the affected circuit.
NO >> GO TO 2.
2.CHECK HEADLAMP (HI) OUTPUT VOLTAGE
CONSULT ACTIVE TEST
1. Turn the ignition switch OFF.
2. Disconnect the front combination lamp harness connector E213 or E222 in question.
3. Turn the ignition switch ON.
4. Select EXTERNAL LAMP of IP DM E/R active test item.
5. With EXTERNAL LAMP ON, check the voltage between the combination lamp connector and ground.
