U0319Software Incompatibility With Steering Effort Control Module
- Generic OBD-II code · Network
- How the car detects it
- 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.
