Steering Column Switch Circuit Failure
Code B2351 indicates a fault in the steering column switch circuit, which is specific to Ford vehicles. This code is triggered when the Body Control Module (BCM) or Generic Electronic Module (GEM/Front Electronic Module) detects an out-of-range voltage, open circuit, or short circuit in the communication bus or signal lines of the steering column switch assembly. The switch assembly integrates functions such as cruise control, lighting, wipers, and other auxiliary systems. A malfunction can cause these features to behave erratically or stop working entirely.
1. Commonly Affected Makes
2. Most Common Causes
- Faulty steering column switch module (clockspring or SCCM damaged)
- Damaged, cut, or corroded wiring in the steering column harness
- Loose, corroded, or damaged pins in the switch connector
- Internal failure of the BCM or GEM/FEM module
- Short to ground or voltage in the switch circuit
- Mechanical wear of the steering column switch assembly
3. Symptoms You Will Notice
- Cruise control, lights, wipers, or other auxiliary functions not working or intermittent
- Warning lights on the dashboard related to steering column controls
- No response from steering wheel switches
4. Step-by-Step Diagnosis
Scan for additional codes and check freeze frame data
Visually inspect the steering column wiring and connectors for damage or corrosion
Test the steering column switch module (clockspring) for continuity and proper operation
Check for shorts or opens in the switch circuit using a multimeter
If wiring and switch are okay, test the BCM/GEM/FEM for proper output signals
5. Frequently Asked Questions
Is it safe to drive?▼
Yes, it is generally safe to drive, but you may lose functionality of cruise control, lights, or wipers. Have it diagnosed soon to prevent further electrical issues.
How much does it cost to fix?▼
Repair costs typically range from $150 to $600, depending on whether the issue is a simple wiring repair or requires replacement of the clockspring or BCM.
