Steering Wheel Switch Circuit Range/Performance
The Steering Column Control Module (SCCM) has detected that the voltage or resistance signal from one or more steering wheel switches (audio, cruise control, voice, etc.) is outside the factory-calibrated range. This indicates a discrepancy in the switch input circuit compared to the reference values stored in the module.
1. Commonly Affected Makes
2. Most Common Causes
- Damaged steering wheel switches with internal resistance out of specification
- Clockspring with open circuits, shorts, or high resistance
- Damaged, corroded, or loose wiring or connectors between the SCCM and switches
- Improper installation of aftermarket accessories on the steering wheel
3. Symptoms You Will Notice
- Malfunctioning steering wheel controls (audio, cruise, voice)
- Illuminated check engine or warning light
4. Step-by-Step Diagnosis
Scan for additional codes and check freeze frame data
Inspect clockspring and wiring for damage or corrosion
Test steering wheel switch resistance and compare to specifications
Check for aftermarket modifications affecting the circuit
If all else passes, test or replace the SCCM
5. Frequently Asked Questions
Is it safe to drive?▼
Yes, it is generally safe to drive, but some steering wheel controls may not work. Have it diagnosed soon to prevent further issues.
How much does it cost to fix?▼
Repair costs typically range from $100 to $500, depending on the root cause (switch, clockspring, or module).
