9359-HEADLIGHT FLASHER / BRIGHTS SWITCH STUCK

For a complete wiring diagram Consult Diagrams/Electrical

Theory of Operation

The Headlight Flasher / Brights switch input changes when the switch is in a forward or aft position. A stored DTC indicates that the Headlight Flasher / Brights switch was stuck in a forward or aft position for predetermined value of time, but has since returned to its normal state. An active DTC indicates that the Headlight Flasher / Brights switch is stuck in a forward or aft position. An active DTC will prevent proper Headlight Flasher / Brights switch and status indicator function.

- When Monitored:
With the ignition on.

- Set Condition:
If the Headlight Flasher / Brights switch stays in a forward or aft position for more than a predetermined value of time.
