U0329 Software Incompatibility With Steering Column Control Module

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modeNo

The steering column control module gathers the stalks and wheel buttons for indicators, wipers, horn and cruise control, and on newer cars it may also handle the heated wheel or pass on the steering angle. U0329 means a partner module rejects the software of this unit. No manufacturer documents U0329 publicly. Ford shows a typical trap on the 2023 Bronco Sport: programming a replacement SCCM in FDRS can abort with a download error when a wrong part variant was fitted, and Ford lists which service part belongs to which engineering assembly number (SSM 52486). FCA updated SCCM software on 2011–2013 Dodge and Ram models because the cruise control reacted slowly or not at all to its switches (08-010-14). U0212 is lost contact, U0429 invalid data, U0328 concerns the angle sensor. Stalk or wheel functions may fail.

Likely causes

Replacement steering column module of the wrong variant fitted
Module installation or programming after replacement not completed
Steering column module software older than the connected modules expect

Symptoms

  • Indicators, wipers or horn work only partly
  • Cruise control or wheel buttons without reaction
  • Assistance functions using steering column signals unavailable
