Heated Seat Components The heated seat system consists of the following components: • Driver and passenger heated seat switches • Driver and passenger seat back heater elements • Driver and passenger seat cushion heater elements • Driver and passenger seat back temperature sensors • Driver seat module • Driver door module • Passenger door module When there are modules involved in the operation of any componet that's acting up , the module's electronic's could be the culprit ! But without testing who's to say what the problem could be ! I would have it check for DTC'S DTC B2425 or B2430 The driver and passenger seat heaters are controlled by the driver seat module. Power is supplied to the driver seat cushion and back heater elements through individual voltage supply circuits. Power is supplied to the passenger seat cushion and back heater elements through a common voltage supply circuit. All of the driver and passenger seat heater elements are grounded by the driver seat module through individual low side drive control circuits. The heater element control circuits are pulse width modulated to ground by the driver seat module in order to control the seat temperatures by regulating the current flow through the heater elements. DTC B2435 or B2440 The driver seat module relies on inputs from thermistors installed in the driver and passenger seat backs to control heated seat temperatures. The thermistors are 2-wire sensors supplied with a 5-volt referenced signal circuit and low reference circuit from the driver seat module. Resistance through the thermistors varies with temperature causing the heated seat sensor signal circuit voltage levels to decrease as the seat back temperatures rise. Install a scan tool. Start the engine. Turn the heated seat ON. With a scan tool, observe the Heated Seat Sensor parameter in the data list for the driver seat module. Does the scan tool indicate that the heated seat sensor parameter is within the specified range? 0.078-4.94 V

Broken wire most likely. Remove the seat cover and find the broken wire and bridge it by soldering in a jumper. Alternatively replace the seat heating element. You may wish to take it to an upholstery shop.

Try depressing the brake pedal and keep it depressed while starting the car and then try to engage a gear.

Look like dealership job.they have to use diagnostic programmer to reprogram it.

Try swapping the front sensors and see if the code moves to the other side. Heated 02 sensors can short the heater circuit into oxygen sense side and it gets confusing. If it doesn't travel with the sensor you'll probably end up having to pin out the sensor wiring. I hope this helps, take care. If you have more questions for me use testimonial. Thanks
