U0319 code meaning
Software Incompatibility With Steering Effort Control Module
What U0319 means
U0319 is set when the steering effort control module, the unit that varies steering assist, for example with road speed, reports a software or calibration identity the network does not accept. J2012 keeps it apart from the power steering control module, which has its own code U0320. GM's generic U03xx description fits: the check runs at 9-16 V with normal bus traffic, and a module that was not configured after installation sets the code; the repair is programming, not wiring. No manufacturer documents U0319 publicly, so which steering unit carries the code is maker-specific. U0130 means lost contact, U0419 invalid data from the same module. Steering may feel heavier or less speed-dependent, a steering warning may light, the MIL normally stays off.
U0319 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 U0319
- Steering heavier or assist no longer speed-dependent
- Steering warning light or message
- Code appears after steering module work
Common causes of U0319
- Most likelySteering module replaced or flashed without setup
- PossibleSoftware variant does not match vehicle configuration
- Less likelyProgramming aborted or wrong file loaded
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U0319 means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 19 | The exact fault in that area. |
What to do next
- Note U0319 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 U0319
What does U0319 mean?
U0319 means "Software Incompatibility With Steering Effort Control Module". U0319 is set when the steering effort control module, the unit that varies steering assist, for example with road speed, reports a software or calibration identity the network does not accept. It is a generic code, so it means the same on every make.
Is it safe to drive with U0319?
U0319 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will U0319 fail an emissions test?
U0319 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 U0319 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 2 hours of work. This is a job for a workshop.
Will U0319 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
