DTC C0292

Diagnostic Instructions

* Perform the Diagnostic System Check - Vehicle (Diagnostic System Check - Vehicle) prior to using this diagnostic procedure.
* Review Strategy Based Diagnosis (Strategy Based Diagnosis) for an overview of the diagnostic approach.
* Diagnostic Procedure Instructions (Diagnostic Procedure Instructions) provides an overview of each diagnostic category.

DTC Descriptor
DTC C0292 00
- VSES Combination Sensor Circuits

Circuit/System Description

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

Conditions for Running the DTC

* Ignition ON.
* Ignition voltage is greater than 8 V.

Conditions for Setting the DTC

The EBCM detects that the sensor supply voltage is less than 4.75 V or greater than 5.25 V for 1 second.

Action Taken When the DTC Sets

* The EBCM turns OFF the 5 V reference circuit, until the ignition is cycled.
* The EBCM disables the traction control system (TCS)/vehicle stability enhancement system (VSES) for the duration of the ignition cycle.
* A DIC message and/or a warning indicator may be displayed.

Conditions for Clearing the DTC

* The condition for setting the DTC is no longer present.
* The EBCM 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 V reference.

Circuit/System Testing

1. Ignition ON, observe the DTC information with the scan tool.

• Verify that none of the following DTCs are set, U0100-U0299. If any of the DTCs are set, refer to Diagnostic Trouble Code (DTC) List - Vehicle (Diagnostic Trouble Code (DTC) List - Vehicle).

2. Ignition OFF, disconnect the yaw rate and lateral acceleration sensor connector.
3. Ignition OFF for 30 seconds, test for less than 15 ohm between the low reference circuit terminal 6 and ground.

• If greater than 15 ohm, test the low reference circuit for an open/high resistance. If the circuits test normal, replace the EBCM.

4. Test the lateral accelerometer 5 V reference circuit terminal 1 for a short to voltage or ground.

• If all circuits test normal, replace the yaw rate sensor/lateral acceleration sensor, cycle the ignition switch and perform the yaw rate sensor recalibration procedure with the scan tool.
• If the DTC sets again after replacing the yaw rate sensor/lateral acceleration sensor, replace the EBCM.

Repair Instructions

Perform the Diagnostic Repair Verification (Verification Tests) after completing the diagnostic procedure.
