DAYTIME LIGHT RELAY CIRCUIT
DAYTIME LIGHT RELAY CIRCUIT
Description
INFOID:0000000006823259
The BCM sends a daytime light request to the IPDM E/R via the CAN communication lines. The power flows
backward through fuse 45 located in IPDM E/R to daytime light relay 1 and LH high beam lamp to IPDM E/R,
through the high beam fuses, through the RH high beam lamp and on to ground. The high beam lamps are
wired in series which causes them to illuminate at a reduced intensity.
Diagnosis Procedure
INFOID:0000000006823260

FRONT FOG LAMP CIRCUIT
FRONT FOG LAMP CIRCUIT
Description
INFOID:0000000006247660
The IPDM E/R (intelligent power distribution module engine room) controls the front fog lamp relay based on
inputs from the BCM via the CAN communication lines. When the front fog lamp relay is energized, power
flows from the front fog lamp relay in the IPDM E/R to the front fog lamps.
Component Function Check
INFOID:0000000006247661
1.
CHECK FRONT FOG LAMP OPERATION
WITHOUT CONSULT-III
1. Activate IPDM E/R auto active test. Refer to
PCS-9, "Diagnosis Description"
2. Check that the front fog lamp is turned ON.
CONSULT-III
1. Select "EXTERNAL LAMPS" of IPDM E/R active test item.
2. With operating the test items, Check that the front fog lamp is turned ON.
Is the front fog lamp turned ON?
YES
>> Front fog lamp circuit is normal.
NO
>> Refer to
.
Diagnosis Procedure
INFOID:0000000006247662
Regarding Wiring Diagram information, refer to
1.
CHECK FRONT FOG LAMP FUSE
1. Turn the ignition switch OFF.
2. Check that the following fuses are not open.
Is the fuse open?
YES
>> Replace the fuse after repairing the affected circuit.
NO
>> GO TO 2
2.
CHECK FRONT FOG LAMP OUTPUT VOLTAGE
