Note 2: When errors are detected in several systems, including the CAN communication system [U1000], trou-
bleshoot the CAN communication system.
DATA MONITOR
Operation Procedure
1. After turning OFF the ignition switch, connect CONSULT-II and the CONVERTER to the data link connec-
tor.
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.
2. Touch ?START (NISSAN BASED VHCL)?, ?ABS?, ?DATA MONITOR? in order on the CONSULT-II screen.
If ?ABS? is not indicated, go to GI-40, "
CONSULT-II Data Link Connector (DLC) Circuit" .
CAUTION:
When ?START (NISSAN BASED VHCL)? is touched immediately after starting the engine or turning
on the ignition switch, ?ABS? might not be displayed in the system selection screen. In this case,
repeat the operation from step 2.
3. Return to the Monitor Item Selection screen, and touch ?C/U INPUT ITEM?, ?MAIN ITEM? or ?ITEM MENU
