FRONT FOG LAMPPFP:26150
Component Parts and Harness Connector LocationAKS007O5
System DescriptionAKS007CI
Control of the front fog lamps is dependent upon the position of the combination switch (lighting switch). The
lighting switch must be in the 2ND position or AUTO position (headlamp is ON) for front fog lamp opera-
tion.When the lighting switch is placed in the fog lamp position the BCM (body control module) receives input
signal requesting the front fog lamps to illuminate. When the headlamps are illuminated, this input signal is
communicated to the IPDM E/R (intelligent power distribution module engine room) across the CAN communi-
cation lines. The CPU (central processing unit) located in the IPDM E/R controls the front fog lamp relay coil.
When activated, this relay directs power to the front fog lamps.
OUTLINE
Power is supplied at all times

through 15A fuse (No. 88, located in IPDM E/R)

to front fog lamp relay, located in IPDM E/R,

through 15A fuse (No. 78, located in IPDM E/R)

to CPU located in IPDM E/R, and

to ignition relay, located in IPDM E/R, from battery direct,

through 10A fuse (No. 71, located in IPDM E/R)

to CPU located in IPDM E/R.
Power is also supplied at all times

through 50A fusible link (letter M, located in fuse, fusible link and relay box)

to BCM terminal 55,

through 15A fuse [No. 22, located in fuse block (J/B)]

to BCM terminal 42.
When ignition switch is in ON or START position, power is supplied

through 15A fuse [No. 1, located in fuse block (J/B)]

CHECK POWER SUPPLY AND GROUND
1. CHECK FUSE
Check if any of the following fuses in the BCM are blown.

Check 50A fusible link (letter M , located in the fuse and fusible link box.)

Check 15A fuse [No.22, located in the fuse block (J/B)]

Check 10A fuse [No.1, located in the fuse block (J/B)]

Check 10A fuse [No.6, located in the fuse block (J/B)]
NOTE:
Refer to SE-15, "
Component Parts and Harness Connector Location" .
OK or NG
OK >> GO TO 2.
NG >> If fuse is blown out, be sure to eliminate cause of malfunction before installing new fuse. Refer to
SE-15, "
Component Parts and Harness Connector Location" .
2. CHECK POWER SUPPLY CIRCUIT (BCM)
1. Turn ignition switch OFF.
2. Disconnect BCM connector.
3. Check voltage between BCM connector and ground.
OK or NG
OK >> GO TO 3.
NG >> Check harness for open and short between BCM and fuse or fusible link.
3. CHECK GROUND CIRCUIT (BCM)
1. Turn ignition switch OFF.
2. Check continuity between BCM connector B14 terminal 49, 52 and ground.
OK or NG
OK >> BCM circuit is OK. Check the driver seat control unit. GO TO 4.
NG >> Repair or replace the harness between BCM and ground.
