U0159 Lost Communication with Parking Assist Module
The Parking Assist Module has stopped transmitting on the vehicle data bus, so other control units no longer receive its messages. Parking sensors and park-assist functions stop working. 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.
