The Heated Steering Wheel Module (HSWM) controls the steering wheel heating elements. It is located in the instrument panel behind the FDIM and can be serviced separately. The Heated Steering Wheel Module (HSWM) uses the steering wheel temperature sensor to maintain the temperature of the steering wheel. The Heated Steering Wheel Module (HSWM) is designed to remain on, heating the steering wheel and maintaining temperature until switched off on the FDIM or the ignition is turned off.
The Heated Steering Wheel Module (HSWM) requires PMI when replaced.
