Heated Seats - Operation

OPERATION

The heated seat system operates on battery current received through fused ignition switch output (Run) circuits and will only operate when the engine is running. The heated seat system will turn off automatically whenever the engine is turned off.

The Body Control Module (BCM) is used to control the heated seat system. The BCM responds to heated seat switch and ignition switch status inputs and operates the heated seat relays, which supply a 12 volt Direct Current (DC) output to the heated seat elements.

The heated seat elements for the selected seat are energized when the heated seat switch is pressed. Light Emitting Diodes (LEDS) on each switch indicate when in use. Pressing the switch once will turn the heating elements on. Pressing the same switch a second time will shut the heating elements off.

The BCM and heated seat switches are diagnosed using a scan tool A L L Diagnostic Trouble Codes ( DTC ).
