Heated Seats - Rear

Vehicles equipped with rear heated seats are equipped with a single-heated seat module to control both rear heated seats. The heated seat module does not time out. The system will function with the ignition in RUN, whether the engine is running or not. The heated seat module supplies voltage to the heater mats and regulates seat temperature by monitoring a thermostat located in the cushion heater mat.

The heated seat buttons are located in the rear panel of the front floor console. When a heated seat button is pressed, a momentary ground is sent to the heated seat module to turn the heated seat on or off. Pressing the high or low button once turns the heated seat on and pressing the same button a second time turns it off. The heated seat module will send voltage to the separate indicator circuit at the heated seat switch to indicate an on state. The heated seat module will remain on until the heated seat switch is pressed for that high or low mode currently on, sending a second momentary ground signal to the heated seat module or the ignition is set to OFF.

When the heated seat module is on, it provides voltage to the separate indicator circuit at the heated seat button to indicate an on state.

The heated seat module does not report DTCs and does not communicate on the CAN  . If a fault is detected, the module will disable the affected seat(s) and indicator(s).

After the fault is corrected, the heated seat module needs to be reset by cycling the ignition OFF and then ON. After the heated seat module has been reset, the module will return to an off state.
