U0328 code meaning
Software Incompatibility With Steering Angle Sensor Module
What U0328 means
The steering angle sensor module reports wheel angle and turning speed over CAN, mainly to stability control and electric power steering. U0328 means a receiving module rejects the software or variant of this sensor. No manufacturer documents U0328 publicly. GM shows how tight the pairing is: on 2012–2013 cars with NJ1 steering, among them Volt, Malibu and Equinox, a wrongly performed sensor alignment set C0544 and U0415 that would not clear, lit the MIL and cut assist; only flashing the steering module with different software removed it (PI0800A). Audi fixed an intermittent low-voltage code B116816 for the angle sensor in the ABS unit of the 2015 A3 with new J500 software and a fresh sensor calibration (2040449). U0126 is lost contact, U0428 invalid data, U0320 concerns the steering module. ESC and lane assist may switch off.
U0328 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor0.5 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of U0328
- ESC, traction control or lane assist warning lamps on
- Steering assist uneven or the car pulls after alignment work
- Code appears after wheel alignment or steering column repair
Common causes of U0328
- Most likelySteering angle sensor or column part replaced without calibration or setup
- PossibleSensor of another part number or software variant fitted
- PossibleBrake or steering module software does not support the fitted sensor
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U0328 means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 28 | The exact fault in that area. |
What to do next
- Note U0328 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 U0328
What does U0328 mean?
U0328 means "Software Incompatibility With Steering Angle Sensor Module". The steering angle sensor module reports wheel angle and turning speed over CAN, mainly to stability control and electric power steering. It is a generic code, so it means the same on every make.
Is it safe to drive with U0328?
Drive gently and only to a workshop. With U0328 the car can go into limp mode (reduced power) to protect itself.
Will U0328 fail an emissions test?
U0328 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 U0328 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 2 hours of work. This is a job for a workshop.
Will U0328 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
