Invalid Data Received From Steering Column Control Module
What it means
U0429 is a network communication code: a module is receiving data from the steering column control module that is corrupt, missing, or out of range. This module handles column-mounted controls — turn signals, wipers, horn, steering-wheel buttons, and often the steering-angle input. Invalid data can disable several of these, so the impact ranges from minor control glitches to disabled steering-assist or stability features depending on the vehicle.
Can I keep driving? Drivable, but steering-column features — turn signals, wipers, cruise, or steering assist — may not work correctly, so verify controls before longer trips.
Common symptoms
What you'll notice
- Turn signals, wiper stalk, or horn not working correctly
- Steering-wheel controls (cruise, audio) unresponsive
- Stability or steering-assist warning lights, where the column feeds steering angle
- Other network warning lights at the same time
Common causes
Most likely first
- Internal fault in the steering column control module sending corrupt dataLikely
- Wiring or connector problems, including the clockspring, on the bus to the moduleCommon
- Low system voltage or a poor ground affecting the moduleCommon
- Module not calibrated or programmed after a repair or replacementLess often
How to diagnose & fix
Work through it in order
- Scan all modules and record freeze-frame data; clear any lost-communication codes first.
- Check battery voltage and the column module's ground.
- Inspect the module connector, clockspring, and bus wiring for damage or loose pins.
- Calibrate or program the module if it was recently serviced.
- If wiring and power are good, suspect the steering column control module and confirm with manufacturer tests.
