U0125 Lost Communication with Multi-axis Acceleration Sensor
The Multi-axis Acceleration Sensor has stopped transmitting on the vehicle data bus, so other control units no longer receive its messages. Several stability and airbag functions lose their motion reference. 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.
