Oh, I completely forgot about that post (obviously- duh me). ?? Makes sense. Sensor too close to element = element not getting as hot as it would if the sensor was the correct distance from the element. ??There are no settings or adjustments in FORScan that can change the temperature of the heated steering wheel.
Steve, you are correct in that there is a variable in manufacturing, however that variable is where the steering wheel heater and sensor are placed in the wheel. I mentioned this a year or so ago in another thread that brought up this question.
The sensor (thermistor) in my premium was placed further away from the heater therefore the steering wheel became hotter. The one in my GTPE was closer to the heater so my wheel barely got warm. I actually pulled the steering wheel apart and dug into the area where the sensor was (at the bottom of the wheel) and moved it away from the heater and it now gets much warmer. I was lucky though as sometimes the sensor is buried in the foam part of the wheel and cannot be accessed without damaging part of the wheel. I know this because I've had several custom steering wheels made for the cars and have had it damaged. Also, you cannot remove the sensor because with it out of the circuit, the heater will not come on.
From the service manual:
Heated Steering Wheel:
When the vehicle is on and the SCCM (Steering Column Control Module) receives a request to heat the steering wheel, the SCCM applies voltage and ground to the steering wheel heating elements to heat the steering wheel to a temperature of approximately 82-94°F (28-34°C). The heated steering wheel temperature is maintained by the SCCM using a temperature sensor in the steering wheel. The SCCM 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
