Self-Diagnosis (Without CONSULT-II)

FUNCTION
When a problem occurs in the ABS, the ABS warning lamp on the instrument panel comes on. When a problem occurs in the TCS, the TCS OFF indicator lamp and SLIP indicator lamp on the instrument panel come on.

To activate the self-diagnostic results mode, ground the self-diagnostic (check) terminal located on data link connector. The location of the malfunction is indicated by the ABS warning lamp or SLIP indicator lamp flashing.

SELF-DIAGNOSIS PROCEDURE
1. Drive vehicle over 30 km/h (19 MPH) for at least one minute.
2. Turn ignition switch OFF.





3. Ground terminal 9 of data link connector with a suitable harness.
4. Turn ignition switch ON while grounding terminal 9.
Do not depress brake pedal.
Do not start engine.





5. After 3.0 seconds, the SLIP indicator lamp starts flashing to indicate the malfunction code No.
6. Verify the location of the malfunction with the malfunction code chart. Refer to "SELF-DIAGNOSTIC RESULTS MODE". Then make the necessary repairs following the diagnostic procedures.
7. After the malfunctions are repaired, erase the malfunction codes stored in the control unit. Refer to "HOW TO ERASE SELF-DIAGNOSTIC RESULTS (MULTIFUNCTION CODES)".
8. Repeat the self-diagnostic procedure to verify that the malfunction codes have been erased.





9. Disconnect the data link connector terminal 9 from ground. The self-diagnostic results mode is now complete.
10. Verify that the ABS warning lamp, TCS OFF indicator lamp and SLIP indicator lamp remain off after driving vehicle over 30 km/h (19 MPH) for at least one minute.
11. After making certain that the ABS warning lamp, TCS OFF indicator lamp and SLIP indicator lamp do not come on, test the ABS/TCS in a safe area to verify that it functions properly.

NOTE: The indication terminates after five minutes. However, when the ignition switch is turned from OFF to ON, the SLIP indication starts flashing again. The TCS OFF indicator lamp and ABS warning lamp remain lighted.

HOW TO READ SELF-DIAGNOSTIC RESULTS (MALFUNCTION CODES)
1. Determine the code No. by counting the number of times the ABS warning lamp or SLIP indicator lamp flashes on and off.
2. When several malfunctions occur at one time, up to three code numbers can be stored; the latest malfunction will be indicated first.
3. The indication begins with the start code 12. After that, a maximum of three code numbers appear in the order of the latest one first. The indication then returns to the start code 12 and the sequence is repeated (the indication will stay on for five minutes at the most).





4. Refer to "SELF-DIAGNOSTIC RESULTS MODE".
