CONSULT-II Function (BCM)EIS002VU
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 carries 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”.
If “BCM” is not indicated, go to GI-39, "
CONSULT-II Data Link
Connector (DLC) Circuit" .

BCM Power Supply and Ground Circuit CheckEIS002VW
1. CHECK FUSES AND FUSIBLE LINK
Check 10A fuse (No. 8, located in the fuse block (J/B)]
Check 10A fuse (No. 59, located in the fuse and relay box)
Check 50A fusible link (letter f , located in the fuse and fusible link box)
NOTE:
Refer to GW-78, "
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 to PG-
4, "POWER SUPPLY ROUTING CIRCUIT" .
2. CHECK POWER SUPPLY CIRCUIT
1. Turn ignition switch ON.
2. Check voltage between BCM connector M18, M20 terminals 38, 70
and ground.
OK or NG
OK >> GO TO 3.
NG >> Repair or replace harness.
3. CHECK GROUND CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect BCM.
3. Check continuity between BCM connector M20 terminal 67 and ground.
OK or NG
OK >> BCM power supply and ground circuit is OK.
NG >> Repair or replace harness.70 (W/B) - Ground : Battery voltage
