- -- '1: Fail-safe operation does not activate. A signal from ABS control unit suspends ABS control operation. Brakes operate con-
ventionally. After specified power supply voltage resumes, ABS warning lamp goes out, allowing for ABS control operation. '2: The code No. does not indicate a malfunction related to the ABS control unit. Do not replace the ABS control unit even if the code No. appears. '3: The code No. can sometimes appear when the ABS motor ground circuit is loose or disconnected. When it appears, always
check the ground circuit for improper installation.
'4: ABS warning lamp turns on if a wheel or wheels spin for 10 to 80 seconds (depending on the wheel speed) with the vehicle
stuck in snow, ice, or mud. This is a normal condition. After repairing short-circuited sensor, turning ignition switch ON lights
up
ABS warning lamp. Check that ABS warning lamp turns off when the vehicle is driven at approx. 30 krnlh for approx. 1 minute as shown in the self-diagnosis procedure.

If the flashing of AIR BAG warning lamp is caused by low battery voltage, self-diagnosis mode cannot be switched from User
mode to Diagnosis mode. In this case, diagnosis with CONSULT displays "NO SELF-DIAGNOSTIC FAILURE INDICATED".
