System DescriptionEIS00B8F
The rear window defogger system is controlled by BCM and IPDM E/R.
The rear window defogger operates only for approximately 15 minutes.
Power is supplied at all times
lthrough 15A fuse (No.46, 47, located in the IPDM E/R)
lto rear window defogger relay (located in the IPDM E/R)
lthrough 50A fusible link [letterG, located in the fuse block (J/B)]
lto BCM terminal 57.

CONSULT-II Function (BCM)
EIS00B8M
CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
CONSULT-II BASIC OPERATION PROCEDURE
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
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”.

lMake sure other systems using the signal of the following systems operate normally.
BCM Power Supply and Ground Circuit CheckEIS00B8O
First perform the “SELF-DIAG RESULTS” in “BCM” with CONSULT-II, when perform the each trouble
diagnosis. Refer toBCS-16, "
CAN Communication Inspection Using CONSULT-II (Self-Diagnosis)".
1.CHECK FUSE
lCheck 10A fuse [No. 1, located in the fuse block (J/B)]
lCheck 50A fusible link (letterGlocated in the fuse and fusible link box)
NOTE:
Refer toGW-47, "
Component Parts and Harness Connector Location".
OK or NG
OK >> GO TO 2.
NG >> If fuse is blown, be sure to eliminate cause of malfunction before installing new fuse. Refer toPG-
4, "POWER SUPPLY ROUTING CIRCUIT".
2.CHECK POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect BCM connector.
3. Turn ignition switch ON.
4. Check voltage between BCM connector M42, M44 terminal 3,
57 and ground.
OK or NG
OK >> GO TO 3.
NG >> Repair or replace harness.
