WARNING: This page is about a different car, the 2004 Pontiac Sunfire and 2004 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.
The following are possible causes of the malfunction:
- A short between the steering wheel module high and low circuits
- An open or a high resistance in the steering wheel module high or low circuits
- A short to ground or a short to voltage in the steering wheel module high or low circuits
- The steering wheel module coil connector
- The SDM connector
- A malfunctioning steering wheel module

- A malfunctioning SDM
Thoroughly inspect the wiring and the connectors. An incomplete inspection of the wiring and the connectors may result in a misdiagnosis, causing a part replacement with the reappearance of the malfunction. If an intermittent malfunction exists, refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems.
