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.
