|Code U1901 Lincoln Description

The yaw rate sensor, roll rate sensor, lateral accelerometer and longitudinal accelerometer are contained in one module called the stability control sensor cluster. The sensor cluster measures the vehicle acceleration, roll rate and yaw rate, then sends the signal through a secondary, dedicated controller area network (CAN2) bus to the ABS module. The ABS module compares the information from the sensor cluster to information it receives from other sensors (brake pedal input or steering wheel rotation sensor) to determine how valid the information is and to determine if a roll-over event is about to occur.
The ABS module provides power to the sensor cluster and ground. The sensor cluster and the ABS module communicate. An open circuit or a short to power or ground on any one of these 4 circuits will cause the ABS module to set a DTC. Also, if the sensor cluster is not mounted in the correct position, with the electrical connector facing the passenger seat, the ABS module will also set DTCs.
