CONSULT-II Functions

AFS00201

CONSULT-II MAIN FUNCTION

In a diagnosis function (main function), there are “WORK SUPPORT”, “SELF-DIAGNOSTIC RESULTS”,
“DATA MONITOR”, “CAN DIAG SUPPORT MNTR”, “ACTIVE TEST”, “FUNCTION TEST”, “ECU PART NUM-
BER”.

CONSULT-II BASIC OPERATION PROCEDURE

Turn ignition switch OFF.

Connect CONSULT-II and CONSULT-II CONVERTER to the
data link connector.

CAUTION:

If CONSULT-II is used with no connection of CONSULT-II
CONVERTER, malfunctions might be detected in self-diag-
nosis depending on control unit which carry out CAN com-
munication.

Turn ignition switch ON.

Touch “START (NISSAN BASED VHCL)”.

TROUBLE DIAGNOSIS

Revision; 2004 April

2003 Murano

SELF-DIAGNOSIS
Description

If an error is detected in the system, ABS warning lamp, VDC OFF indicator lamp, SLIP indicator lamp on the
combination meter turn on. In this case, perform self-diagnosis as follows.

Operation Procedure

Turn ignition switch OFF.

Connect CONSULT-II and CONSULT-II CONVERTER to the data link connector.

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 performs CAN communication.

Turn ignition switch ON.

Start engine and drive at approximately 30 km/h (19 MPH) for approximately 1 minute.

After stopping the vehicle, with engine running at idle speed, touch “START (NISSAN BASED VHCL)”,
“ABS”, “SELF-DIAG RESULTS” in order on the CONSULT-II screen.
If “ABS” is not indicated, go to

GI-38, "CONSULT-II Data Link Connector (DLC) Circuit"

CAUTION:

●

If there is no error during CONSULT-II use, ABS warning lamp, VDC OFF indicator lamp, SLIP
indicator lamp may be turned ON/OFF.

●

If “START (NISSAN BASED VHCL)” is touched immediately after starting engine or turning on
ignition switch, “ABS” might not be displayed in the System Selection screen. In this case,
repeat the operation from step 1. If it connect be shown after several attempts, ABS actuator
and electric unit (control unit) may have malfunction. Repair or replace control unit.

The self-diagnostic results are displayed. (If necessary, the self-diagnostic results can be printed out by
touching “PRINT”.)

●

When “NO FAILURE” is displayed, check ABS warning lamp, VDC OFF indicator lamp, and SLIP indi-
cator lamp.

Conduct the appropriate inspection from the display item list, and repair or replace the malfunctioning
component.

Start engine and drive at approximately 30 km/h (19 MPH) for approximately 1 minute.

CAUTION:

●

When a wheel sensor “short-circuit” is detected, if the vehicle is not driven at 30 km/h (19 MPH)
for at least 1 minute, ABS warning lamp will not turn off even if everything is normal.

●

Check again to make sure that there is no malfunction on other parts.

Turn ignition switch OFF to prepare for erasing the memory.

10. Start engine and touch “START (NISSAN BASED VHCL)”, “ABS”, “SELF-DIAG RESULTS”, “ERASE

MEMORY” in order on the CONSULT-II screen to erase the error memory.

CAUTION:

If the error memory is not erased, re-conduct the operation from step 5.

11. For the final inspection, drive at approximately 30 km/h (19 MPH) for approximately 1 minute and confirm

that ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp are OFF.
