ABS Light: Testing and Inspection

ABS Warning Light/Brake Warning Light Illumination Pattern





INSPECTION
1) When the ABS warning light does not illuminate in accordance with this illumination pattern, there must be an electrical malfunction.
2) When the ABS warning light remains constantly OFF, repair the ABS warning light circuit or diagnosis circuit.

NOTE: Even though the ABS warning light does not go out about 2 seconds after it illuminates, the ABS system operates normally when the warning light goes out while driving at approximately 12 km/h (7 MPH). However, the Antilock brakes do not work while ABS warning light is illuminated.
