CONSULT-II Function (BCM)EKS00BCW
CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
CONSULT-II BASIC OPERATION 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 carries out CAN communication.
1. With the ignition switch OFF, connect CONSULT-II and CON-
SULT-II CONVERTER to the data link connector, and 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-40, "
CONSULT-II Data Link Connector (DLC)
Circuit" .
BCM
diagnostic test item Diagnostic mode
Description
Inspection by part WORK SUPPORT
Supports 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.
