DTC Descriptor
DTC C0914 06
- Device Voltage Output 1 Circuit Short to Ground or Open

Conditions for Running the DTC

* Ignition ON.
* The ignition voltage is greater than 10 volts.

Conditions for Setting the DTC

The EBCM has detected a short to ground or open on the yaw and lateral accelerometer sensor ignition circuit.

Action Taken When the DTC Sets

* The EBCM disables the traction control and the 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 the DTC is no longer present.
* The EBCM clears the history DTC when a current DTC is not detected in 40 consecutive drive cycles.

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the yaw and lateral accelerometer sensor.
2. Ignition OFF, test for less than 5.0 ohm between the low reference circuit terminal 6 and ground.

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

3. Ignition ON, test for B+ between the ignition circuit terminal 1 and ground.

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

4. If the circuits test normal, replace the yaw and lateral accelerometer sensor.
