Lost Communication with Tire Pressure Monitor Module
The Tire Pressure Monitor Module has stopped transmitting on the vehicle data bus, so other control units no longer receive its messages. Tire-pressure monitoring stops and warns the driver. 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.
