Internal fault. Permanent fault
Check the control module for the steering wheel angle sensor
- Ignition off
- Disconnect the connector for the steering wheel module (SWM)
- Wait 150 seconds
- Connect the connector to the steering wheel module (SWM)
- Ignition on
- Read off diagnostic trouble codes (DTCs) for the control module for the steering wheel angle sensor.
The EEPROM in the control module stores diagnostic trouble codes (DTC), diagnostic trouble code (DTC) counters and frozen values. If the memory circuit is malfunctioning, no information can be read from the control module. Simulate a fault to check the condition of the memory. This stores a diagnostic trouble code (DTC). The memory can then be checked by reading off the diagnostic trouble code (DTC) information.
Note! A diagnostic trouble code (DTC) will be stored in the steering wheel module (SWM) when the module is disconnected. Therefore any diagnostic trouble codes (DTCs) in the system for the steering wheel module (SWM) must be erased.
Other information:
- To disconnect and connect the connector for the steering wheel module (SWM), see Steering wheel module (SWM), replacing Service and Repair.
Can the diagnostic trouble codes (DTCs) be read off?
Yes - Fault-tracing information
No - Replacing the control module for the steering wheel angle sensor

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
