Code U0212 Mercury Description
The U0212 diagnostic trouble code (DTC) for Mercury vehicles indicates that there has been a communication failure between the vehicle's engine control module (ECM) and the steering column control module (SCCM). The SCCM is responsible for various functions related to the steering system, such as controlling power steering assist, steering wheel angle sensor data, and other steering-related functions. When communication is lost between the ECM and SCCM, it can lead to issues with the vehicle's steering performance and safety systems.
Common Causes of U0212 Mercury
- Faulty steering column control module
- Wiring or connector issues between ECM and SCCM
- ECM software or hardware malfunction
- Electrical interference or communication bus issues
- Water or corrosion damage to connectors or wiring
Symptoms of U0212 Mercury
- Loss of power steering assist
- Steering wheel may feel stiff or difficult to turn
- Steering wheel angle sensor warning light on the dashboard
- Vehicle stability control system warning light illuminated
How to Fix U0212 Mercury
- Begin by conducting a thorough inspection of the wiring and connectors between the ECM and SCCM to check for any visible damage or corrosion. Repair or replace any damaged wiring or connectors.
- Use a diagnostic scan tool to communicate with the SCCM and ECM to identify the specific communication fault. Clear the code and retest to see if the issue persists.
- If the problem persists, consider replacing the steering column control module with a new or remanufactured unit. Ensure proper programming and initialization of the new module.
- Perform a final test drive to verify that the communication between the ECM and SCCM is restored, and that all steering functions are operating correctly.
- Clear the diagnostic trouble codes and reset any warning lights on the dashboard.
Cost to Fix U0212 Mercury
The typical repair costs for addressing a U0212 code on a Mercury vehicle can vary depending on the specific cause of the communication failure and the cost of parts and labor. In general, the cost of replacing a steering column control module can range from $300 to $800, including parts and labor. Additional costs may be incurred for diagnostic testing, wiring repairs, or other related components. It is advisable to consult with a qualified mechanic or repair shop to obtain a more accurate estimate based on the specific circumstances of the vehicle. Keep in mind that labor rates at auto repair shops can vary, so it's recommended to inquire about rates in your local area for a more precise cost estimate.
