Circuit/System Description

For an overview of the component/system, refer to:Steering Wheel and Column Description and Operation.

Diagnostic Aids

• Before replacing the steering wheel for complaints of not getting hot enough, a reliable infrared temperature gun should be used to measure the temperature at the 3 and 9 o'clock positions (1).
• The target temperature of the steering wheel heating is 30ºC (86ºF), which can take up to 20 min to reach.
• The steering wheel heating will not operate when the steering wheel temperature is above 32ºC (89.6ºF).
