TROUBLE DIAGNOSIS
Revision: 2005 August 2005 350Z
Note 1: After completing repairs of the shorted sensor circuit, when ignition switch is turned ON, ABS warning
lamp turns on. Check that ABS warning lamp turns off while driving the vehicle at approximately 30 km/h (19
MPH) or more for approximately 1 minute according to self-diagnosis procedure. In addition, if wheel sensor 2
is displayed for the wheels, check the wheel sensor circuit and also check the control unit power voltage.
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-39, "
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 ?ECM INPUT SIGNALS?, ?MAIN SIGNALS? or
?SELECTION FROM MENU?. Refer to the following information.
4. When ?START? is touched, the data monitor screen is displayed.
