U0429

Invalid Data Received From Steering Column Control Module

Q: Is it safe to drive with U0429?

Usually yes for short trips, but check that turn signals and wipers work first, since the column module runs those. If steering assist or stability control is affected, drive with extra care.

Q: Can I just clear U0429?

It returns while the module reports bad data, and it may need programming after service. Diagnose the wiring and clockspring, then the module itself.

Communication network Generic OBD-II Medium

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.

Medium

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.
