CONSULT-II MAIN FUNCTION

CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.

CONSULT-II SETTING PROCEDURE

NFS000RG

Refer to

GI-37, "CONSULT-II Start Procedure"

.

Self-Diagnosis

NFS000KQ

DESCRIPTION

If a malfunction is detected in system, ABS warning lamp, VDC OFF indicator lamp and SLIP indicator lamp
on meter turn on. In this case, perform self-diagnostic as follows:

OPERATION PROCEDURE

1.

Turn ignition switch OFF.

2.

Perform “CONSULT-II Start Procedure”. Refer to

GI-37, "CONSULT-II Start Procedure"

.

3.

Turn ignition switch ON.

4.

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

5.

After stopping vehicle, with engine still idling, touch “SELF-DIAG RESULTS” on CONSULT-II screen in
this order.

CAUTION:

Just after starting engine, or turning ignition switch ON, “ABS” may not be displayed on system
selection screen even if “START” is touched. In this case, start self-diagnostic again from step 1. If
it cannot be shown after several attempts, VDC/TCS/ABS control unit may have malfunctioned.
Repair or replace control unit.

6.

Self-diagnostic results is displayed. (If necessary, touch “PRINT” to print self-diagnostic results.)

●

When “NO FAILURE” is shown, check ABS warning lamp, VDC OFF indicator lamp, SLIP indicator
lamp. Refer to

BRC-32, "For Fast and Accurate Diagnosis"

.

●

CONSULT-II self-diagnostic results are displayed without regard to occurrence timing. In some cases
later ones (timing value is small) appear on next screen.

7.

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

8.

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

CAUTION:

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

TROUBLE DIAGNOSIS

ERASE MEMORY

1.

Turn ignition switch OFF.

2.

Start the engine and touch “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, perform applicably diagnosis.

3.

Perform self-diagnosis again, and make sure that diagnostic memory is erased.

4.

Drive vehicle at 30 km/h (19 MPH) or more for approximately 1 minute as the final inspection, and make
sure that the ABS warning lamp, VDC OFF indicator lamp and SLIP indicator lamp turn off.
