U0131 Lost Communication with Power Steering Control Module
The Power Steering Control Module has stopped transmitting on the vehicle data bus, so other control units no longer receive its messages. Electric power steering can fail, requiring much higher steering effort. Typical causes are loss of power or ground at the module, an open or shorted CAN/LIN bus wire, a connector fault, or an internal module failure.
