B1148-2A-LEFT REAR HEATED SEAT SWITCH - STUCK

For a complete wiring diagram, refer to the Wiring Information.

Theory of Operation

The Left Rear Heated Seat Switch is momentary, push button-type switch, that provides a hard-wired resistance signal to the Heated Seat Module (HSM), signaling it to energize the heating element in the left seat. Light Emitting Diodes (LED) in the switch indicate the level of heat in use. The Left Rear Seat Switch LEDs are controlled by the HSM.

- When Monitored:
Continuously with the ignition on.

- Set Condition:
The Heated Seat Module (HSM) senses that the Left Rear Heated Seat Switch is pressed for greater than 45 seconds.
