U0329
Software Incompatibility With Steering Column Control Module
Network / communication
Generic OBD-II
Medium
What it means
U0329 means the steering column control module is running software that doesn't match the rest of the network — typically after a module swap or an interrupted update. Column functions and, on some vehicles, electric power-steering assist may be affected. Steering stays mechanically connected, but effort can increase, so drive carefully until the module is reprogrammed.
Medium
Can I keep driving? Yes, but with care — on vehicles where this module handles power-steering assist, assist can drop; steering stays mechanical but effort may increase.
Common symptoms
What you'll notice
- Power steering, ESC, or airbag warning lights on
- Heavier steering effort if electric assist is affected
- Steering-column controls (tilt/telescope, stalk functions) not responding
- Other modules log lost-communication codes for the steering column module

- Replacement or used module installed without correct programmingCommon
- Interrupted reflash or incomplete module setup/calibrationCommon
- Coding out of sync after a related steering or body module was reprogrammedLess often
How to diagnose & fix
Work through it in order
- Scan all modules and confirm which software/part numbers are mismatched.

- Reflash or recode the module to the manufacturer-approved software level.
- Complete any required calibration or relearn, then clear and re-test.
