SELF-DIAGNOSIS
Description
If an error is detected in the system, the ABS warning lamp will turn on. In this case, perform self-diagnosis as
follows:
Operation Procedure
1. Turn ignition switch OFF.
2. Connect CONSULT-III To the data link connector.
3. Turn ignition switch ON.
4. Start engine and drive at approximately 30 km/h (19 MPH) for approximately 1 minute.
5. After stopping the vehicle, with the engine running, t ouch “ABS”, “SELF-DIAG RESULTS” in order on the
CONSULT-III screen.

6. The self-diagnostic results are displayed. • When “NO DTC IS DETECTED” is displayed, check the ABS warning lamp, SLIP indicator lamp and
VDC OFF indicator lamp.
7. Conduct the appropriate inspection from the display item list, and repair or replace the malfunctioning
component.
8. 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, the ABS warn ing lamp will not turn off even if the malfunction is repaired.
9. Turn ignition switch OFF to prepare for erasing the memory.
10. Start the engine and touch “ABS”, “SELF-DIAG RESULTS”, “ERASE” in order on the CONSULT-III screen to erase the error memory.
If “ABS” is not indicated, go to GI-36, "
CONSULT-III Data Link Connector (DLC) Circuit".
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 the ABS warning lamp, SLIP indicator lamp, and VDC OFF indicator lamp are off.

• The active test cannot be performed with the AB S warning lamp, VDC indicator lamp, SLIP indicator
lamp or brake warning lamp on.
• ABS warning lamp, VDC OFF indicator lamp, SLIP indicator lamp and brake warning lamp are on
during active test.
NOTE:
• When active test is performed while depressing the pedal, the pedal depression amount will change. This is normal. (Only solenoid valve and ABS motor)
• “TEST IS STOPPED” is displayed 10 seconds after operation start.
• After “TEST IS STOPPED” is displayed, to perform test again, touch BACK.
