3: ABS Warning Light Does Not Illuminate When Key Is Turned On

Inspection Procedure 3:

HINT:
When power is supplied to the ABS-ECU, the valve relay changes from "ON" to "OFF." Turned on by the initial check, and thus even if there is a problem with the circuit between ABS warning light and ABS-ECU, the light will illuminate once when the valve relay is off. Accordingly, the cause of the light not illuminating is probably an open circuit in the light power circuit, a blown light bulb, or an open circuit in both the circuit between the ABS warning light and the ABS-ECU and the circuit between the ABS warning light and the ABS valve relay. When other warning lights also do not illuminate. the cause is probably a blown fuse.

PROBABLE CAUSE:
- Blown fuse.
- Burnt out ABS warning light bulb.
- Malfunction of the wiring harness or connector.
