TROUBLE DIAGNOSIS


CONSULT-III Function (ABS)

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











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) or more for approximately 1 minute.
5. After stopping the vehicle, with the engine running, use CONSULT-III to perform ABS "SELF-DIAG
RESULTS".
6. The self-diagnostic results are displayed.
- When "NO DTC IS DETECTED" is displayed, check the ABS warning 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) 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, the ABS warning 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 return to ABS "SELF-DIAG RESULTS", select "ERASE" for the CONSULT-III to erase the error memory.
If "ABS" is not indicated, go to 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) or more for approximately 1 minute and confirm that the ABS warning lamp is off.
