2010 Cadillac CTS Sedan AWD V6-3.6L Page 689
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.
