U0429 code meaning
Invalid Data Received From Steering Column Control Module
What U0429 means
U0429 covers the steering column control module (SCCM), which reads stalks and wheel buttons and on many cars also houses the steering angle sensor. A partner logs the code when SCCM frames are received but rejected. Ford's 2024 OBD summary lists U0429_48 in the supervision layer of the PCM's throttle monitor as a non-MIL fault. Stellantis calls the sender SCM: U0429 is among the codes a PCM flash removes on the 2021 Chrysler 300 3.6 L (18-013-22), and on a 2023 Jeep Compass with C221F and an EPS lamp, a vehicle configuration restore and PROXI alignment clear it, not a new EPS (STAR S2319000006). Mercedes notes U042986 in the power steering unit when the Kostal column module signal is wrong (LI82.90-P-080159). U0428 is a stand-alone angle sensor module; U0212 lost contact, U0329 software.

What each part of U0429 means

What to do next
- Note U0429 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
