Circuit/System Description
The lateral accelerometer and the yaw rate sensors are combined into one sensor external to the electronic brake control module (EBCM). The vehicle stability enhancement system (VSES) uses the lateral accelerometer input when calculating the desired yaw rate. The usable output signal is a serial data signal CAN high and CAN low serial data circuits.
Conditions for Running the DTC
The ignition switch is in the ON position.
Conditions for Setting the DTC
| • | The yaw/lateral combination sensor fails an internal self test. |
| • | Communication is lost between the EBCM and the yaw/lateral combination sensor. |
| • | The correlation error between the yaw/lateral combination sensor and steering angle sensor . |
Action Taken When the DTC Sets
One or more of the following actions may occur:
| • | The vehicle stability enhancement system (VSES) is disabled. |
| • | Traction control system (TCS) is disabled. |
| • | The TCS/VSES indicators illuminates. |
| • | The driver information center (DIC) displays the Service Traction Control, and or Service StabiliTrak message. |
Conditions for Clearing the DTC
| • | The condition for the DTC is no longer present. |
| • | The EBCM automatically clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles. |

Circuit/System Description
The lateral accelerometer and the yaw rate sensors are combined into one sensor. The sensors communicate through the serial data network to the Vehicle Stability Control Module along with other control modules to perform stability control. The vehicle stability enhancement system (active front steering with enhanced stabilitrak JL7) uses the lateral accelerometer input when calculating the desired yaw rate.
Conditions for Running the DTC
| • | The ignition is ON. |
| • | 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
C0196 09
The Yaw Rate combination sensor changes by more than 455 degrees/second per second.
C0196 3B
The Yaw Rate combination sensor fails an internal self test.
C0196 39
The Yaw Rate combination sensor has an internal electronic failure.
C0196 1A
The Yaw Rate combination bias exceeds 5.7 degrees/second.
C0196 75
The Yaw Rate combination signal above allowable range.
Action Taken When the DTC Sets
| • | The stability control system disables the VSES for the duration of the ignition cycle. |
| • | The driver information center (DIC) displays the SERVICE STABILITY SYS message. |
| • | The ABS/TCS remains functional. |
Conditions for Clearing the DTC
| • | The condition for setting the DTC is no longer present. |
| • | The EBCM automatically clears a history DTC when a current DTC is not detected in 100 consecutive drive cycles. |
Diagnostic Aids
| • | Check the vehicle for proper steering alignment. |
| • | The Snapshot function on the scan tool can help find an intermittent DTC. |
