When the HSWM receives a request to heat the steering wheel, the HSWM applies voltage and ground to the steering wheel heating elements (integral to the steering wheel) to heat the steering wheel to a temperature of approximately 28-34 deg.C (82-94 deg.F). The heated steering wheel temperature is maintained by the HSWM using a temperature sensor in the steering wheel.

The HSWM is designed to remain on, heating the steering wheel and maintaining the temperature until switched off on the FDIM or the ignition is turned off.

The controls and indicators for the heated steering wheel system are located on the FDIM (touchscreen) only. The FDIM does not communicate on any network and is connected directly to the APIM.

When the SECM receives a request to heat the steering wheel and the engine is running, the SECM applies voltage and ground to the steering wheel heating elements (integral to the steering wheel) to heat the steering wheel to a temperature of approximately 28-34 deg.C (82-94 deg.F). The heated steering wheel temperature is maintained by the SECM using a temperature sensor in the steering wheel.

The SECM is designed to remain on, heating the steering wheel and maintaining the temperature until switched off on the FDIM or the ignition is turned off.
