Circuit Operation
WARNING: This page is about a different variant/trim than selected.
- The ABS warning light power is supplied from the ignition switch. The ABS-ECU grounds the circuit to illuminate the light.
- The ABS-ECU illuminates the ABS warning light for 3 seconds while running self-check. This light can be illuminated for 3 seconds upon start-up or when the ignition switch is turned to the "ON" position with engine stopped.
- When the ABS-ECU connector is disconnected, the circuit is grounded to illuminate the light by the ABS warning light relay ON operation.
- The ABS-ECU controls the continuity to the ABS warning light by turning the power transistor in the unit "OFF" and "ON" to turn the ABS warning light relay "ON" and "OFF", respectively.
