DTC C0292
Diagnostic Fault Information
• Perform the "Diagnostic System Check - Vehicle
Diagnostic Information: " prior to using this diagnostic
procedure.
• Review "Strategy Based Diagnosis: " for an overview
of the diagnostic approach.

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 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. Ignition OFF, 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 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.
➢ If all circuits test normal, replace the yaw rate
sensor/lateral accelerometer.
➢ If the DTC sets again after replacing the yaw rate
sensor/lateral accelerometer, replace the EBCM.
Repair Instructions
