How to Proceed With Trouble DiagnosisEKS00B7Z
1. Confirm the symptom or customer complaint.
2. Understand operation description and function description. Refer to LT- 6 , "
System Description" .
3. Perform the Preliminary Check. Refer to LT- 1 5 , "
Preliminary Check" .
4. Check symptom and repair or replace the cause of malfunction.
5. Does the headlamp operate normally? If YES: GO TO 6. If NO: GO TO 4.
6. Inspection End.
Preliminary CheckEKS00B80
CHECK POWER SUPPLY AND GROUND CIRCUIT
1. CHECK FUSES OR FUSIBLE LINK
Check for blown fuses or fusible link.

CONSULT-II Function (BCM)EKS00B81
CONSULT-II can display each diagnostic item using the diagnostic test modes 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, then turn igni-
tion switch ON.
2. Touch "START (NISSAN BASED VHCL)".
3. Touch "BCM" on "SELECT SYSTEM" screen.
If "BCM" is not indicated, go to GI-39, "
CONSULT-II Data Link
Connector (DLC) Circuit" .
BCM diagnostic
test itemDiagnostic mode Description
Inspection by partWORK SUPPORTSupports inspections and adjustments. Commands are transmitted to the BCM
for setting the status suitable for required operation, input/output signals are
received from the BCM and received data is displayed.
DATA MONITOR Displays BCM input/output data in real time.
ACTIVE TEST Operation of electrical loads can be checked by sending drive signal to them.
SELF-DIAG RESULTS Displays BCM self-diagnosis results.
CAN DIAG SUPPORT MNTR The result of transmit/receive diagnosis of CAN communication can be read.
ECU PART NUMBER BCM part number can be read.
CONFIGURATION Performs BCM configuration read/write functions.
