Heated Seats

When LO is pressed on the Heated Seat Switch and the Ignition Switch is in RUN, the Heated Seat Control Module LO input terminal is momentarily grounded. This causes the Seat Control Module to turn on the LO LED indicator and apply voltage to the Seat Heaters. The Heated Seat Control Module monitors the seat surface temperature through a thermistor located in the Center Seat Bottom. The Heated Seat Control Module will maintain the seat surface temperature at approximately 37°C (98°F) when LO has been selected.

Operation of the Heated Seat in the HI mode is similar to LO operation except the HI LED indicator will be lit and seat surface temperature will be maintained at approximately 42°C (107°F).

When the OFF switch is pressed, the Heated Seat Control Module's OFF input (terminal C1/F) is grounded momentarily. The module will react by turning off the voltage applied to the seat heates. The module will also turn off the Heated Seats whenever the Ignition Switch has been cycled OFF and then back to RUN.
