Circuit/System Description

The longitudinal/ lateral accelerometer and the yaw rate sensors are combined into one sensor. The sensors communicate through the serial data

network to the EBCM along with other control modules to perform stability control. The vehicle stability enhancement system uses the

longitudinal/lateral accelerometer input when calculating the desired yaw rate.

Conditions for Running the DTC

The ignition switch is in the ON position.

DTC C0561 71 is not set as a result of a lateral acceleration sensor circuit or internal fault during the current ignition cycle.

Conditions for Setting the DTC

C0186 09

The lateral accelerometer combination changes by more than 550 meters/second per second.

C0186 0F

The lateral accelerometer combination sensor is not mounted properly.

C0186 55

The lateral accelerometer combination signal does not change and is locked on a constant value.

C0186 3B

The lateral accelerometer combination sensor fails an internal self test.

C0186 1A

The lateral accelerometer combination bias exceeds 3 meters/second.

C0186 5A

The lateral acceleration sensor signal is not plausible with the yaw rate sensor signal, steering angle sensor signal and vehicle speed.

C0186 75

The lateral accelerometer combination signal above allowable range.

C0196 09

The yaw rate combination sensor changes by more than 455 degrees/second per second.

C0196 0F

The yaw rate combination sensor is not mounted properly.

C0196 3B

The yaw rate combination sensor fails an internal self test.

C0196 39

The yaw rate combination sensor has an internal electronic failure.
