Without CONSULT Scan Tool

FUNCTION
^ When a problem occurs in the ABS, the warning lamp on the instrument panel comes on. To actuate the self-diagnostic results mode, ground the self-diagnostic (check) terminal located on "Data link connector for CONSULT". The location of the malfunction is indicated by the warning lamp flashing.

Please refer to Procedure Chart parts 1 and 2.

How to Read Self-Diagnostic Results (Malfunction Codes)






- Determine the code No. by counting the number of times the warning lamp flashes on and off.
- When several malfunctions occur at one time, up to three code numbers can be stored; the latest malfunction will be indicated first.
- 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 to repeat (the indication will stay on for five minutes at the most).






- The malfunction code chart is illustrated.

How to Erase Self-Diagnostic Results (Malfunction Codes)

1. Under the self-diagnostic results mode, the malfunction memory erase mode starts when the check terminal is disconnected from the ground.






2. The self-diagnostic results (malfunction codes) can be erased by grounding the check terminal more than three times in succession within 12.5 seconds after the erase mode starts. (Each grounding must be longer than one second.)
The ABS warning lamp stays on while the self-diagnosis is in the erase mode, and goes out after the erase operation has been completed.
3. The self-diagnosis is also completed at the same time.

NOTE: After the erase operation is completed, it is necessary to rerun the self-diagnostic mode to verify that malfunction codes no longer appear. Only the start code (12) should be indicated when erase operation is completed and system is functioning normally.
