How to Proceed With Trouble DiagnosisEKS00Q83
1. Confirm the symptom or customer complaint.
2. Understand operation description and function description. Refer toLT-49, "
System Description".
3. Carry out the Preliminary Check. Refer toLT-58, "
Preliminary Check".
4. Check symptom and repair or replace the cause of malfunction. Refer toLT-62, "
Trouble Diagnosis Chart
by Symptom".
5. Does the auto light system operate normally? If YES, GO TO 6. If NO, GO TO 4.

CONSULT-II Function (BCM)EKS00Q85
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)”.
