Heated Steering Wheel

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°C (82-94°F). The heated steering wheel temperature is maintained by the HSWM using a temperature sensor in the steering wheel.

For vehicles built on 6/24/15 or later, the HSWM has four available temperature setpoints that can be set through two programmable parameters using a diagnostic scan tool. The HSWM programmable parameters can be used to set the operating temperature of the heated steering wheel between normal or warm and between warmer or hot. Refer to: Module Configuration - System Operation and Component Description .

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.

Remote Start System 

The heated steering wheel system (along with the heated front seats) may be configured using the message center to activate when the remote start feature is used, based on outside air temperature. During remote start, the outside air temperature is continually evaluated by the HVAC system. The heated steering wheel system activation changes if the outside air changes from cold to moderate or warm temperatures or back from moderate or warm to cold temperatures.
