B135C Meaning

When steering wheel heat is requested and the engine is running, the Heated Steering Wheel Module (HSWM) applies voltage and ground to the steering wheel heating element (integral to the steering wheel). The steering wheel heating element draws between 1 and 10 amps of current depending on steering wheel temperature. The HSWM uses a sensor in the steering wheel (integral to the steering wheel) to maintain the heated steering wheel temperature. The HSWM is designed to remain on, heating the steering wheel and maintaining temperature until switched OFF using the FDIM or the ignition is turned OFF. The OBDII code sets when the heated steering wheel is commanded on and the HSWM senses current greater than 10 amps or less than 1 amp from the steering wheel heating element output circuit, indicating a short to ground or voltage, or when the steering wheel heating element output Field Effect Transistor (FET) in the HSWM has a thermal failure. When this fault sets, the steering wheel heating element output is disabled until the ignition is cycled.
