The yaw rate and the lateral accelerometer 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 yaw rate/lat sensor communicates with the EBCM via discrete CAN Bus High and CAN Bus Low serial data circuits.
The engine is running.
• | Short to ground on the CAN High serial data circuit. |
• | 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 . |
One or more of the following actions may occur:
• | The EBCM disables the antilock brake system (ABS)/traction control system (TCS) and vehicle stability enhancement system (VSES) for the duration of the ignition cycle. |
• | The ABS indicator illuminates. |
• | The Stabilitrak indicator illuminates. |
• | The driver information center (DIC) displays All Wheel Drive Off/ Service Traction Control / Service Stabilitrak message. |
• | The condition for the DTC is no longer present. |
• | The EBCM clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles. |

⇒ | If the DTC is set, refer to DTC C0710 . |
⇒ | If greater than the specified range, test the low reference circuit for an open/high resistance. |
⇒ | If not within the specified range, test the ignition voltage circuit for a short to ground or open/high resistance. |
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
