CONSULT-II Functions (BCM)NKS003PI
CONSULT-II can display each diagnostic item using the diagnostic test mode shown following.
NOTE:
Cannot change setting for headlamp.
CONSULT-II BASIC 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 carry 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, check power supply and ground of
BCM. If it is normal, refer to GI-40, "
CONSULT-II Data Link Con-
nector (DLC) Circuit" .
BCM diagnosis part Diagnosis mode Description
HEADLAMPWORK SUPPORT
Changes the setting for each function.
NOTE
DATA MONITOR Displays BCM input data in real time.
ACTIVE TEST Operation of electrical loads can be checked by sending drive signal to them.
BCMSELF-DIAG RESULTS BCM performs self-diagnosis of CAN communication.
CAN DIAG SUPPORT MNTR The result of transmit/receive diagnosis of CAN communication can be read.
