How to Proceed With Trouble DiagnosisEKS00P8A
1. Confirm the symptom or customer complaint.
2. Understand operation description and function description. Refer toLT-97, "
System Description".
3. Perform preliminary check. Refer toLT- 1 0 3 , "
Preliminary Check".
4. Check symptom and repair or replace the cause of malfunction.
5. Do turn signal and hazard warning lamps operate normally? If YES, GO TO 6. If NO, GO TO 4.
6. INSPECTION END
Preliminary CheckEKS00P8B
CHECK POWER SUPPLY AND GROUND CIRCUIT
1.CHECK FUSES OR FUSIBLE LINK
Check for blown fuses or fusible link.
Refer toLT-100, "Wiring Diagram—TURN—".
OK or NG
OK >> GO TO 2.

CONSULT-II Function (BCM)EKS00P8C
CONSULT-II can display each diagnostic item using the diagnostic test mode shown following.
CONSULT-II OPERATION
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. With the ignition switch OFF, connect CONSULT-II and CON-
SULT-II CONVERTER to the data link connector, and then turn
ignition switch ON.
2. Touch “START (NISSAN BASED VHCL)”.
3. Touch “BCM” on “SELECT SYSTEM” screen.
If “BCM” is not indicated, refer toGI-50, "
CONSULT-II Data Link
Connector (DLC) Circuit".

TURN SIGNAL AND HAZARD WARNING LAMPS
4.CHECK TURN SIGNAL LAMP CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect BCM connector, front combination lamp (RH and LH) connector, side turn signal lamp (RH
and LH) connector and rear combination lamp (RH and LH) connector.
3. Check continuity between BCM harness connector (A) and front
combination lamp (RH and LH) harness connector (B).
4. Check continuity between BCM harness connector (A) and side
turn signal lamp (RH and LH) harness connector (B).
5. Check continuity between BCM harness connector (A) and rear
combination lamp (RH and LH) harness connector (B).
OK or NG
OK >> GO TO 5.
NG >> Repair harness or connector.
5.CHECK SIGNAL LAMP CIRCUIT (SHORT CIRCUIT)
Check continuity between BCM harness connector and ground.
OK or NG
OK >> Replace BCM if turn signal lamp does not work after set-
ting the connector again. Refer toBCS-17, "
Removal
and Installation of BCM".
NG >> Repair harness or connector.
