ABS WARNING LIGHT ILLUMINATION PATTERN

10.ABS Warning Light Illumination Pattern

A: 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 cir-
cuit. <Ref. to ABS-28, Diagnostics Chart with Diagnosis Connector.>  

NOTE:
Even though the ABS warning light does not go out 1.5 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 Anti-
lock brakes do not work while the ABS warning light is illuminated.
