DTC Descriptor

DTC C0252 00: VSES Sensor Uncorrelated

The vehicle stability enhancement system (VSES) is activated by the electronic brake control module (EBCM) and monitors the yaw rate/lateral accelerometer sensor, and steering wheel angle sensor inputs to ensure they correlate within their desired ranges.

Conditions for Running the DTC

•	The steer angle has been centered.

•	The VSES is active.

•	The centered lateral acceleration value is less than 0.5 g.

•	The yaw rate error is less than 6 degrees/second.

Conditions for Setting the DTC

One of the following conditions exists:

•	The DTC sets when VSES is engaged for 10 seconds with the yaw rate error always in either understeer or oversteer.

•	The yaw rate error is greater then 10 degrees/second for 5 seconds, and the yaw has not changed and the lateral acceleration is less than 0.5 g.

Action Taken When the DTC Sets

One or more of the following actions may occur:

•	The EBCM disables the ABS/TCS/VSES for the duration of the ignition cycle.

•	The ABS and VSES indicators illuminate.

•	The driver information center (DIC) displays the Service Traction Control and 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.

Diagnostic Aids

The following conditions can cause this concern:

•	Improper steering alignment

•	An internal lateral accelerometer failure

Circuit/System Verification

Perform the steering angle sensor calibration.
Clear the DTC with a scan tool, and operate the vehicle within the conditions for setting the DTC.
Verify DTCs : C0186, C0196, C0252, C0253, or C0710 are not set.

⇒	If DTCs C0186, C0196, C0253, or C0710 are set, refer to Diagnostic Trouble Code (DTC) List - Vehicle

⇒	If only DTC C0252 set as current, replace the EBCM.
