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 driver information center 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 B119 Multi-axis Acceleration Sensor.
2. Ignition OFF and all vehicle systems OFF. It may take up to 2 minutes for all vehicle systems to power down. Test for less than 10 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 K17 EBCM.

3. Ignition ON, test for B+ between the ignition circuit terminal 5 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 K17 EBCM.

4. If the circuits test normal, replace the B119 Multi-axis Acceleration Sensor.
