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 5-volt reference to the combination yaw/lateral accelerometer sensor. The supply voltage is monitored via an internal feedback circuit in the EBCM.

Conditions for Running the DTC

Ignition voltage is greater than 9 volts.

Conditions for Setting the DTC

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

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 driver information center (DIC) displays the Service Stabilitrak 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.

Diagnostic Aids

If the yaw/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 harness connector at the yaw/lateral accelerometer sensor.
  2. Test for less than 1 ohm between the low reference circuit terminal 6 and ground.
    3. ⇒If greater than 1 ohm, test the low reference circuit for a short to voltage or an open/high resistance. If the circuits test normal, replace the EBCM.
  3. Ignition ON, test for less than 1 volt between the following circuits listed below and ground.
    4. • 5-volt reference circuit terminal 1
    • yaw signal circuit terminal 3
    • lateral accelerometer signal circuit terminal 2
    • yaw frequency circuit terminal 5
    ⇒If greater than the specified range, test the appropriate circuit for a short to voltage. If the circuits test normal, replace the EBCM.
  4. Ignition OFF, test for infinite resistance between the following circuits listed below and ground.
    5. • 5-volt reference circuit terminal 1
    • yaw signal circuit terminal 3
    • lateral accelerometer signal circuit terminal 2
    • yaw frequency circuit terminal 5
    ⇒If not the specified value, the appropriate circuit for a short to ground. If the circuit test normal, replace the combination yaw/lateral accelerometer sensor.
  5. Disconnect the harness connector at the EBCM.
  6. Test for less than 1 ohm between the following terminals listed below.
    7. • 5-volt reference circuit terminal 1 and 23
    • yaw signal circuit terminal 3 and 37
    • lateral accelerometer signal circuit terminal 2 and 8
    • yaw frequency circuit terminal 5 and 38
    ⇒If greater than the specified range, test the appropriate circuit for an open/high resistance. If the circuit test normal, replace the combination yaw/lateral accelerometer sensor.
  7. If all circuits test normal, replace the EBCM.
