HOW TO ERASE SELF-DIAGNOSTIC RESULTS (Malfunction codes)1. Disconnect the check terminal from ground (ABS warning lamp will stay lit.)
2. Within 12.5 seconds, ground the check terminal three times. Each terminal ground must last more than one second. The ABS warning lamp goes out after the erase operation has been completed.
3. Perform self-diagnosis again. Only the start-code should appear, no malfunction codes.
