U0319 Software Incompatibility With Steering Effort Control Module

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modeNo

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.

Likely causes

Steering module replaced or flashed without setup
Software variant does not match vehicle configuration
Programming aborted or wrong file loaded

Symptoms

  • Steering heavier or assist no longer speed-dependent
  • Steering warning light or message
  • Code appears after steering module work
