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

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 8 volts.

Conditions for Setting the DTC

The EBCM detects that the sensor supply voltage is less than 4.75 volts or greater than 5.25 volts for 30 milliseconds.

Action Taken When the DTC Sets
    • The EBCM turns OFF the 5 volt 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.
    • The antilock brake system (ABS) indicator turns on.
    • The vehicle dynamics caution (VDC) indicator turns on.
    • The driver information center (DIC) displays the SERVICE STABILITRAK 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 ABS indicator may remain illuminated after repairs are made and DTCs are cleared, until the vehicle is operated at speeds greater than 13 km/h (8 mph) and the self test is completed.
    • 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 acceleometer 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. Ignition OFF, test for less than 1 ohm of resistance between the low reference circuit and ground.
    3. ⇒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, the 5 volt reference circuit, and the low reference circuit for an open/high resistance or a short to voltage or ground.
    4. ⇒If all circuits test normal, replace the yaw rate sensor/lateral accelerometer, and clear the yaw rate sensor offset value in the EBCM.
    ⇒If the DTC sets again after replacing the yaw rate sensor/lateral accelerometer, replace the EBCM.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
