U0192Lost Communication With Personal Computer
- Generic OBD-II code · Network
- How the car detects it
- U0192 is reserved for a personal computer that exchanges data with the vehicle network, for example a built-in carputer, a docked laptop in a police or service vehicle, or a PC-based infotainment unit. When that node stops sending, a listening module stores the code. No manufacturer documents U0192 publicly: the Saab U-code lists from GM omit it, the NHTSA bulletin index has no match, and GM's preliminary information PIP5094 only names it among keywords for checking terminal fit before circuit tests. GM's procedure for U0100-U02FF gives the usual rule, a supervised periodic message missing at 9-16 V. First confirm that a PC is fitted at all; a stray entry after a retrofit or recoding is likely. U0493 is invalid data. No MIL, driving unaffected.
