DTC Descriptor
DTC C0292
- VSES Combination Sensor Circuits




Circuit/System Description

The electronic brake control module (EBCM) supplies a reference voltage of 12 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 illuminates.
* 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.
* The EBCM automatically clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles.

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the yaw rate/lateral accelerometer sensor.
2. Test for less than 5 ohms of resistance between the low reference circuit terminal 5 and ground.

• If greater than the specified range, test for an open/high resistance in the low reference circuit. If the circuit tests normal, replace the EBCM.

3. Ignition ON, test for B+ between the voltage circuit terminal 3 and ground.

• If less than the specified range, test the B+ circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the EBCM.

4. Ignition OFF, disconnect the harness connector at the EBCM.
5. Ignition ON, test for 0 volts between the CAN bus low circuit terminal 1 and ground at the yaw rate/lateral accelerometer sensor connector.

• If greater than the specified value, test the CAN bus low circuit for a short to voltage.

6. Test for 0 volts between the CAN bus high circuit terminal 2 and ground.

• If greater than the specified value, test the CAN bus high circuit for a short to voltage.

7. If all circuits test normal, replace the yaw rate/lateral accelerometer.
