U0429 Ford Code - Invalid Data Received From Steering Column Control Module
Quick Answer
The U0429 diagnostic trouble code (DTC) for Ford vehicles indicates that the Engine Control Module (ECM) has detected invalid data being received from the Steering Column Control Module (SCCM). Common causes include Faulty Wiring: Damaged or corroded wiring connections between the SCCM and ECM can disrupt data transmission and trigger the U0429 code, Defective SCCM Module: A malfunctioning SCCM module can send incorrect data to the ECM, leading to the detection of invalid data, Communication Errors: Issues with communication protocols between the SCCM and ECM can result in data discrepancies and trigger the U0429 code. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code U0429 Ford Description
The U0429 diagnostic trouble code (DTC) for Ford vehicles indicates that the Engine Control Module (ECM) has detected invalid data being received from the Steering Column Control Module (SCCM). The SCCM is responsible for various functions related to the steering column, such as controlling steering wheel position sensors, steering wheel angle sensors, and other steering-related components. When the ECM receives data from the SCCM that does not match expected values or is outside of normal parameters, it triggers the U0429 code.
Common Causes of U0429 Ford
- Faulty Wiring: Damaged or corroded wiring connections between the SCCM and ECM can disrupt data transmission and trigger the U0429 code.
- Defective SCCM Module: A malfunctioning SCCM module can send incorrect data to the ECM, leading to the detection of invalid data.
- Communication Errors: Issues with communication protocols between the SCCM and ECM can result in data discrepancies and trigger the U0429 code.
- Damaged Connectors: Loose or damaged connectors between the SCCM and ECM can cause intermittent data transmission issues.
- Software Glitches: Software glitches or programming errors within the SCCM or ECM can also lead to the detection of invalid data.
Symptoms of U0429 Ford
- Illuminated Check Engine Light: The most obvious symptom of the U0429 code is the illumination of the Check Engine Light on the vehicle's dashboard.
- Erratic Steering Behavior: Drivers may experience erratic steering behavior, such as the steering wheel feeling loose or unresponsive.
