C0371

DTC C0371

Circuit Description
The electronic brake control module (EBCM) monitors the yaw rate of the vehicle for vehicle stability enhancement system operation.

DTC Descriptor
This diagnostic procedure supports the following DTC:
DTC C0371 Yaw Rate Sensor Performance

Conditions for Running the DTC
DTC C0371 can be set anytime the ignition is in the ON position.

Conditions for Setting the DTC
The EBCM detects malfunction in the deceleration sensor.

Action Taken When the DTC Sets
^ The ABS is disabled.
^ The ABS warning indicator turns ON.
^ The traction control and vehicle stability control (VSC) is disabled.
^ The VSC warning indicator turns ON.

Conditions for Clearing the DTC
The condition responsible for setting the DTC no longer exists and the scan tool Clear DTCs function is used.

Diagnostic Aids
Thoroughly inspect the wiring and the connectors. An incomplete inspection of the wiring and the connectors may result in a misdiagnosis, causing a part replacement with the reappearance of the malfunction.
The following are possible causes of the malfunction:
^ An open or high resistance in the deceleration voltage circuit
^ An open or high resistance in the deceleration sensor ground circuit
^ A deceleration sensor malfunction
If an intermittent malfunction exists, refer to Testing for Intermittent Conditions and Poor Connections. Component Tests and General Diagnostics
