Heated Steering Wheel

WARNING: This page is about a different car, the 2016 Dodge Durango. However, it is still accessible from the selected car via links, so may be relevant.

Operation of the steering wheel heating element is controlled by the Heated Seat Module (HSM). The Steering Column Control Module is the interface between the heated steering wheel and the vehicle. The HSM provides power to the heated steering wheel heating elements in the steering wheel. A temperature sensor is integrated into the steering wheel heating element that sends the temperature of the steering wheel to the steering wheel switch. The steering wheel switch sends this information over the LIN bus to the SCCM. The SCCM then sends this information over the CAN C bus to the Body Control Module (BCM). The BCM sends this information to the HSM over the CAN I bus. The normal heating cycle of the steering wheel will last up to 50 minutes on high setting, unless the switch is pressed again. The heated steering wheel system will automatically shut off if the heating element reaches a temperature greater than 46° C (115° F), or if a fault is detected. If for any reason a fault in the heated steering wheel system becomes present, a Diagnostic Trouble Code (DTC) will set.

Auto On Feature

The Auto On feature is a customer configurable feature that when enabled will activate the driver heated seat and heated steering wheel on engine start based on ambient temperature. If Auto On feature is enabled, and the ambient temperature is at or below 40° F the HSM will activate the driver heated seat and heated steering wheel feature at the high level during engine start. This feature also works with Remote Start.

The heated steering wheel system is diagnosed using a scan tool. Refer to DIAGNOSIS AND TESTING .

The steering wheel heating element is not serviced separately from the steering wheel and if inoperative or damaged, the entire steering wheel assembly must be replaced. Refer to WHEEL, STEERING, REMOVAL .
