U0329 code meaning
Software Incompatibility With Steering Column Control Module
What U0329 means
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.
U0329 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor0.5 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of U0329
- Indicators, wipers or horn work only partly
- Cruise control or wheel buttons without reaction
- Assistance functions using steering column signals unavailable
Common causes of U0329
- Most likelyReplacement steering column module of the wrong variant fitted
- PossibleModule installation or programming after replacement not completed
- PossibleSteering column module software older than the connected modules expect
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U0329 means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 29 | The exact fault in that area. |
What to do next
- Note U0329 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.
Questions about U0329
What does U0329 mean?
U0329 means "Software Incompatibility With Steering Column Control Module". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with U0329?
U0329 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will U0329 fail an emissions test?
U0329 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is U0329 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 2 hours of work. This is a job for a workshop.
Will U0329 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
