CONSULT-II Function (ALL MODE AWD/4WD)
EDS001L4
FUNCTION
CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
CONSULT-II SETTING 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.
NOTE:
For details, refer to the separate “CONSULT-II Operations Instruction”.
1.
Turn ignition switch “OFF”.
2.
Connect CONSULT-II and CONSULT-II CONVERTER to data
link connector on vehicle.
3.
Turn ignition switch “ON”.
4.
Touch “START (NISSAN BASED VHCL)”.
5.
Touch “ALL MODE AWD/4WD”.
If “ALL MODE AWD/4WD” is not indicated, go to
SULT-II Data Link Connector (DLC) Circuit"
.
6.
Perform each diagnostic test mode according to each service
procedure.
ALL MODE AWD/4WD diagnostic mode
Description

If the engine starts when there is something wrong with the 4WD system, the 4WD warning lamp turns ON or
flickers in the combination meter. When the system functions properly, the warning lamp turns ON when the
ignition switch is turned to “ON”, and it turns OFF after engine starts. To locate the cause of a problem, start
the self-diagnosis function. The 4WD warning lamp in the combination meter will indicate the problem area by
