DTC Descriptor

DTC C0914 06

-
Control Module Voltage Output 1 Circuit Low Voltage/Open

Diagnostic Fault Information






Conditions for Running the DTC

* Vehicle ON or Vehicle in Service Mode.

* The ignition voltage is greater than 10 V.

Conditions for Setting the DTC

The electronic brake control module has detected a short to ground or open on the yaw and lateral accelerometer sensor ignition circuit.

Action Taken When the DTC Sets

* The ABS indicator turns ON.

* The red brake indicator turns ON.

* The traction control/stability control indicator turns ON.

* The Service Brake Assist and Service StabiliTrak messages are displayed on the driver information center.

* The electronic brake control module disables the antilock brake system, the traction control system and the electronic stability control for the duration of the drive cycle.

Conditions for Clearing the DTC

* The condition for setting the DTC is no longer present.

* The history DTC will clear after 40 consecutive fault-free drive cycles have occurred.

Circuit/System Testing

1. Vehicle OFF and all vehicle systems OFF, disconnect the harness connector at the B119 multi-axis acceleration sensor. It may take up to 2 minutes for all vehicle systems to power down.

2. Test for less than 10 ohms between the ground circuit terminal 6 and ground.

• If 10 ohms or greater

1. Vehicle OFF.

2. Test for less than 2 ohms in the ground circuit end to end.

• If 2 ohms or greater, repair the open/high resistance in the circuit.

• If less than 2 ohms, repair the open/high resistance in the ground connection.

• If less than 10 ohms

3. Vehicle in Service Mode.

4. Verify a test lamp illuminates between the ignition circuit terminal 5 and ground.

• If the test lamp does not illuminate

1. Vehicle OFF, disconnect the harness connector at the K17 electronic brake control module.

2. Test for infinite resistance between the ignition circuit and ground.

• If less than infinite resistance, repair the short to ground on the circuit.

• If infinite resistance

3. Test for less than 2 ohms in the ignition circuit end to end.

• If 2 ohms or greater, repair the open/high resistance in the circuit.

• If less than 2 ohms, replace the K17 electronic brake control module.

• If the test lamp illuminates

5. Replace the B119 multi-axis acceleration sensor.

6. Verify the DTC does not set while operating the vehicle under the Conditions for Running the DTC.

• If the DTC sets

Replace the K17 electronic brake control module.

• If the DTC does not set

7. All OK.
