PARKING, LICENSE PLATE AND TAIL LAMPS
How to Proceed with Trouble Diagnosis
INFOID:0000000005394970
1. Confirm the symptom or customer complaint.
2. Understand operation description and function description. Refer to LT-75, "
System Description" .
3. Perform the preliminary check. Refer to LT-82, "
Preliminary Check" .
4. Check symptom and repair or replace the cause of the malfunction.
5. Do the parking, license plate and tail lamps operate normally? If YES, GO TO 6. If NO, GO TO 4.
6. Inspection End.
Preliminary CheckINFOID:0000000005394971
CHECK POWER SUPPLY AND GROUND CIRCUIT FOR BCM
Refer to BCS-16, "BCM Power Supply and Ground Circuit Inspection" .
CHECK POWER SUPPLY AND GROUND CIRCUIT FOR IPDM E/R
Refer to PG-27, "IPDM E/R Power/Ground Circuit Inspection" .
CONSULT-III Function (BCM)INFOID:0000000005394972
Refer to LT-13, "CONSULT-III Function (BCM)" .
CONSULT-III Function (IPDM E/R)INFOID:0000000005394973
Refer to LT-14, "CONSULT-III Function (IPDM E/R)" .
Parking, License Plate and Tail Lamps Do Not IlluminateINFOID:0000000005394974
1.CHECK TAIL LAMP FUSE
Inspect tail lamp 10A fuse (No. 37, located in IPDM E/R).
OK or NG
OK >> GO TO 2.
NG >> Repair harness.
2.CHECK COMBINATION SWITCH INPUT SIGNAL
With CONSULT-III
1. Select “BCM” on CONSULT-III. Select “HEAD LAMP” on “SELECT TEST ITEM” screen.
2. Select “DATA MONITOR” on “SELECT DIAG MODE” screen. Make sure “LIGHT SW 1ST” turns ON-OFF
linked with operation of lighting switch.
Without CONSULT-III
Refer to LT-66, "
Combination Switch Inspection" .
OK or NG
OK >> GO TO 3.
NG >> Check combination switch (lighting switch). Refer to LT-66, "
Combination Switch Inspection" .
3.ACTIVE TEST
With CONSULT-III
1. Select “IPDM E/R” on CONSULT-III, and sele ct “ACTIVE TEST” on “SELECT DIAG MODE” screen.
2. Select “EXTERNAL LAMPS” on “SELECT TEST ITEM” screen.
3. Touch “TAIL” on "ACTIVE TEST" screen.
4. Make sure parking, license plate and tail lamps operate.
Without CONSULT-III When lighting switch is 1ST
position
: LIGHT SW 1ST ON
Parking, license plate and tail lamps should oper-
ate.

ILLUMINATION
ILLUMINATION
System DescriptionINFOID:0000000005394998
The control of the illumination lamps operation is dependent upon the position of the lighting switch. When the
lighting switch is placed in the 1ST or 2ND position, the BCM (body con\
trol module) receives input signal
requesting the illumination lamps to illuminate. This i nput signal is communicated to IPDM E/R (intelligent
power distribution module engine room) across CAN communication lines. CPU (central processing unit)
located in the IPDM E/R controls the tail lamp relay coil. This relay, when energized, directs power to the illu-
mination lamps, which then illuminate.
Power is supplied at all times
• to ignition relay, located in IPDM E/R,
• to tail lamp relay, located in IPDM E/R,
• through 15A fuse (No. 52, located in IPDM E/R) and
• through 20A fuse (No. 53, located in IPDM E/R)
• to CPU located in IPDM E/R,
• through 40A fusible link (letter g, located in fuse and fusible link box)
• to BCM terminal 70, and
• through 10A fuse [No. 8, located in fuse block (J/B)]
• to BCM terminal 57.
With the ignition switch in the ON or START position, power is supplied
• to ignition relay, located in IPDM E/R, and
• through 10A fuse [No. 6, located in fuse block (J/B)]
• to BCM terminal 38.
With the ignition switch in the ACC or ON position, power is supplied
• through 10A fuse [No. 20, located in fuse block (J/B)]
• to BCM terminal 11.
Ground is supplied
• to BCM terminal 67
• through grounds M57 and M61
• to IPDM E/R terminals 39 and 59, and
• through grounds E15 and E24.
ILLUMINATION OPERATION BY LIGHTING SWITCH
With the lighting switch in the 1ST or 2ND position, BCM receives input signal requesting the illumination
lamps to illuminate. This input signal is communica ted to IPDM E/R across CAN communication lines. CPU
located in the IPDM E/R controls the tail lamp relay coil, which, when energized, directs power
• through 10A fuse (No. 37, located in IPDM E/R)
• through IPDM E/R terminal 29
• to illumination control switch terminal 1
• to VDC OFF switch terminal 3 (with VDC)
• to audio unit (with audio unit) or AV control unit (with premium audio system) terminal 9
• to front air control terminal 5
• to A/T shift selector terminal 3 (with 4-speed A/T)
• to CVT shift selector terminal 3 (with CVT)
• to hazard switch terminal 3
• to combination meter terminal 12
• to door mirror remote control switch terminal 16
• to combination switch (spiral cable) terminal 26 (with steering wheel audio control switches)
• to steering wheel audio control switches through combination switch (spiral cable) terminal 18 (with steering wheel audio control switches).
Ground is supplied
• to VDC OFF switch terminal 4 (with VDC)
• to illumination control switch terminal 3, and
• through grounds M57 and M61.
The illumination control switch controls illumination intensity by varying the ground to the following
• through illumination control switch terminal 2
• to audio unit (with audio unit) or AV control unit (with premium audio system) terminal 8
• to front air control terminal 6
• to A/T shift selector terminal 4 (with 4-speed A/T)
• to CVT shift selector terminal 3 (with CVT)
