CONSULT-II SETTING 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 performs CAN communication.

●

For further information, see the CONSULT-II Operation Manual.

Turn ignition switch “OFF”.

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

Turn ignition switch “ON”.

Touch “START (NISSAN BASED VHCL)”.

Touch “ABS”.
If “ABS” is not indicated, go to

GI-39, "CONSULT-II Data Link

Connector (DLC) Circuit"

ACTIVE TEST

Diagnostic Test Mode in which CONSULT-II drives some actuators apart from
the ABS actuator and electric unit (control unit) and also shifts some parameters
in a specified range.

SELF-DIAG RESULT MODE
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

Perform “CONSULT-II SETTING PROCEDURE”. Refer to

BRC-68, "CONSULT-II SETTING PROCE-

DURE"

Start engine and drive at approximately 30 km/h (19 MPH) or more 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-39, "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) or more 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.
