CONSULT-II Function (BCM)AIS004R7
CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
1. Turn ignition switch “OFF”.
2. Connect “CONSULT-II” and CONSULT-II CONVERTER to data link connector.
3. Turn ignition switch “ON”.
4. Touch “START (NISSAN BASED VHCL)”.
5. Touch “BCM”. If “BCM” is not indicated, go to GI-39
, “CONSULT-II Date Link
Connector (DLC) Circuit”
6. Touch “REAR DEFOGGER”.
BCM diagnostic test item Check item diagnostic test mode Content REAR DEFOGGER Data monitor Displays the input data of BCM in real time.
Active test Gives a drive signal to a load to check the operation.

BCM Power Supply and Ground Circuit CheckAIS004R9
First perform the “SELF-DIAG RESULTS” in “BCM” with CONSULT-II, when perform the each trouble
diagnosis. Refer to BCS-15, "
CAN Communication Inspection Using CONSULT-II (Self-Diagnosis)" .
1. CHECK FUSE
Check 15A fuse [No.1, located in the fuse block (J/B)]
Check 15A fuse [No.22, located in the fuse block (J/B)]
Check 50A fusible link (letter M located in the fuse and fusible link box).
NOTE:
Refer to GW-86, "
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. Turn ignition switch ON.
2. Check voltage between BCM connector M3, M4 terminal 38, 42, 55 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 49, 52 and ground.
OK or NG
OK >> Power supply and ground circuit are OK.
NG >> Check BCM ground circuit for open or short. 38 (W/L) – Ground : Battery voltage
42 (L/R) – Ground : Battery voltage
55 (G) – Ground : Battery voltage
PIIA6160E
49 (B) – Ground : Continuity should exist.
52 (B) – Ground : Continuity should exist.

1. CHECK REAR WINDOW DEFOGGER SWITCH OPERATION
With CONSULT-II
Check (“REAR DEF SW”, “IGN ON SW”) in DATA MONITOR mode with CONSULT-II.
Without CONSULT-II
1. Turn ignition switch ON.
2. Check voltage between BCM connector ground.
OK or NG
OK >> Rear window defogger switch is OK.
NG >> GO TO 2.
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 M64 terminal 16.
OK or NG
OK >> GO TO 3.
