DTC Descriptor

DTC C0292

VSES Combination Sensor Circuits

Circuit/System Description

The electronic brake control module (EBCM) supplies a reference voltage of 5 volts to the yaw rate sensor lateral accelerometer and the steering wheel position sensor. The sensor supply voltage is monitored via an internal feedback circuit to the EBCM microprocessor.

Conditions for Running the DTC

* The ignition is ON.
* Ignition voltage is greater than 9.5 volts.

Conditions for Setting the DTC

The yaw/lateral sensor is setting an internal electronic failure.

Action Taken When the DTC Sets

* Vehicle stability enhancement system (VSES) is disabled
* The VSES indicator turns ON.
* The driver information center (DIC) displays the Service ESC message.

Conditions for Clearing the DTC

* The condition for setting the DTC is no longer present and the DTC is cleared with a scan tool.
* The EBCM automatically clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles.

Diagnostic Aids

If the yaw and lateral accelerometer sensor is disconnected, DTCs will set and the EBCM will not provide 5 volt reference.

Circuit/System Testing

1. Ignition OFF, disconnect the yaw rate sensor/lateral accelerometer connector.
2. Test for less than 1 ohm of resistance between the low reference circuit and ground.
^ If greater than 1 ohm, test the low reference circuit and the EBCM ground circuit for a short to voltage or an open/high resistance. If the circuits test normal, replace the EBCM.

3. Test the lateral accelerometer signal circuit, and the 5 volt reference circuit for an open/high resistance or a short to voltage or ground.
^ If all circuits test normal, replace the yaw rate sensor/lateral accelerometer.

4. Perform the Diagnostic Test Drive.
^ If the DTC set as a current DTC, replace the EBCM.

^ If the DTC did not set as a current DTC, see Diagnostic Aids.
