Initial Inspection and Diagnostic Overview

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.

HOW TO READ SELF-DIAGNOSTIC RESULTS (Malfunction codes)

Code Output Format:

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).

HOW TO ERASE SELF-DIAGNOSTIC RESULTS (Malfunction codes)






1. Start the malfunction memory erase mode. To do so, disconnect the check terminal from the ground under the self- diagnostic results mode.
2. Erase the self-diagnostic results (malfunction codes). To do so, after erase mode starts, ground check terminal more than three times within 12.5 seconds. (Each grounding must be longer than one second.) The ABS warning lamp stays on while the erase mode. Then it goes out after the erase operation has been completed. The self-diagnosis is also completed at the same time. After the erase operation, rerun the self-diagnostic mode. Verify that malfunction codes no longer appear. When the system Is functioning normally, only the start code should be indicated.
