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, t ouch “ABS”, “SELF-DIAG RESULTS” in order on the
CONSULT-III screen.
6. The self-diagnostic results are displayed. (If nece ssary, the self-diagnostic results can be printed out by
touching “PRINT”.)
• 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 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 RESU LTS”, “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) or more for approximately 1 minute and
confirm that the ABS warning lamp is off.
Display Item List FUNCTION TEST Conducted by CONSULT-III in
stead of a technician to determine whether each sy stem is "OK" or "NG".
ECU PART NUMBER ABS actuator and electric unit (control unit) part number can be read.
