Check BCM Power Supply and Ground Circuit BIS00107
First perform the “SELF-DIAG RESULTS” in “BCM” with CONSULT-II, when perform the each trouble
diagnosis. Refer to BCS-14, "
CAN Communication Inspection Using CONSULT-II (Self-Diagnosis)" .
1. CHECK FUSE

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

15A fuse [No.17, located in fuse block (J/B)]

50A fusible link (letter M, located in the fuse and fusible link box).
NOTE:
Refer to GW-54, "
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
PG-3, "
POWER SUPPLY ROUTING CIRCUIT" .
2. CHECK POWER SUPPLY CIRCUIT
Check voltage between BCM connector and ground.
OK or NG
OK >> GO TO 3.
NG >> Check BCM power supply circuit for open or short.
3. CHECK GROUND CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect BCM connector.
3. Check continuity between BCM connector M4 terminal 52 and
ground.
OK or NG
OK >> Power supply and ground circuit are OK.
NG >> Check BCM ground circuit for open.

Check Rear Window Defogger Switch Circuit BIS00108
1. CHECK REAR WINDOW DEFOGGER SWITCH OPERATION
With CONSULT-II
Check “REAR DEF SW ” in DATA MONITOR mode with CONSULT-II.
Without CONSULT-II
1. Turn ignition switch ON.
2. Check voltage between BCM connector and ground.
OK or NG
OK >> Rear window defogger switch circuit is OK.
NG >> GO TO 2. (with navi or display unit)
>> GO TO 4. (except with navi or display unit)
2. CHECK HARNESS CONTINUITY
1. Turn ignition switch OFF.
2. Disconnect BCM and A/C and AV switch connector.
3. Check continuity between BCM connector M3 terminal 9 and A/
C and AV switch connector M40 terminal 9.
4. Check continuity between BCM connector M3 terminal 9 and
ground.
OK or NG
OK >> GO TO 3.
NG >> Repair or replace harness.When rear window defogger switch is turned to ON

3. CHECK BCM OUTPUT SIGNAL
1. Connect BCM connector.
2. Turn ignition switch ON.
3. Check voltage between BCM connector M3 terminal 9 and
ground.
OK or NG
OK >> Replace A/C and AV switch.
NG >> Replace BCM.
Check Rear Window Defogger Power Supply Circuit BIS00109
1. CHECK FUSE

10A fuse [No.12, located in fuse block (J/B)]

20A fuse (No.75, located in the IPDM E/R)
NOTE:
Refer to GW-54, "
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
PG-3, "
POWER SUPPLY ROUTING CIRCUIT" .
2. CHECK POWER SUPPLY CIRCUIT
1. Remove rear window defogger relay.
2. Turn ignition switch ON.
3. Check voltage between rear window defogger relay connector
and ground.
OK or NG
OK >> GO TO 3.
NG >> Repair or replace harness between fuse block (J/B) and
rear window defogger relay.
3. CHECK REAR WINDOW DEFOGGER RELAY
Check continuity between rear window defogger terminals 3 and 5.
OK or NG
OK >> GO TO 4.
NG >> Replace rear window defogger relay.9 (GR/L) – Ground : Approx. 5V
