Diagnostic Fault Information






Circuit/System Description

The yaw rate, lateral acceleration and longitudinal acceleration sensors are combined into one multi-axis acceleration sensor, external to the electronic brake control module. The electronic brake control module supplies a 12 V reference voltage to the multi-axis acceleration sensor. The multi-axis acceleration sensor communicates with the electronic brake control module via serial data. The electronic brake control module activates the stability control function depending on multi-axis acceleration sensor input.

Conditions for Running the DTC

Ignition ON

Conditions for Setting the DTC

C0187 5A

* The lateral acceleration sensor offset is out of specified range.

* An Internal fault in multi-axis acceleration sensor will set this DTC.

* Improperly mounted or loose multi-axis acceleration sensor may set this DTC.

* The lateral acceleration sensor signal is not plausible with the yaw rate sensor signal, steering angle sensor signal and vehicle speed.

C018B 5A

The lateral acceleration sensor signal is out of specified range.

C0196 5A and C0196 71

* The yaw rate sensor offset is out of specified range.

* An Internal fault in multi-axis acceleration sensor will set C0196 5A.

* Improperly mounted or loose multi-axis acceleration sensor may set this DTC.

* The yaw rate sensor signal is not plausible with the lateral acceleration sensor signal, steering angle sensor signal and vehicle speed.

C0196 00 or C019B 5A

The yaw rate sensor signal is out of specified range.

C0287 00

The longitudinal acceleration sensor is out of specified range.

C0287 71

The electronic brake control module received an invalid longitudinal acceleration sensor signal.

C0287 4B

The longitudinal acceleration sensor calibration has not been learned.

C0287 5A

* An Internal fault in multi-axis acceleration sensor will set this DTC.

* Improperly mounted or loose multi-axis acceleration sensor may set this DTC.

* The longitudinal acceleration sensor signal is not plausible with the vehicle acceleration.

C0297 4A

Invalid serial data received from multi-axis acceleration sensor.

Action Taken When the DTC Sets

* The traction control/stability control indicator turns ON.

* The electronic brake control module disables the stability control and hill start assist for the duration of the ignition 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 ignition cycles have occurred.

Circuit/System Testing

1. Ignition ON.

2. Verify that DTC C0287 4B is not set.

If the DTC is set

Perform the Vehicle Yaw Sensor Learn Testing and Inspection.

If the DTC is not set

3. Verify the B119 Multi-axis Acceleration Sensor is installed correctly.

If loose or incorrect installation

Correct the installation of the component.

If installed correctly

4. Ignition OFF, scan tool disconnected, and all vehicle systems OFF, disconnect the harness connector at the B119 Multi-axis Acceleration Sensor. It may take up to 2 min for all vehicle systems to power down.

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

If 10 ohms or greater

1. Ignition 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

6. Ignition ON.

7. Verify a test lamp illuminates between the 12 V reference circuit terminal 5 and ground.

If the test lamp does not illuminate

1. Ignition OFF, disconnect the harness connector at the K17 Electronic Brake Control Module.

2. Test for infinite resistance between the 12 V reference 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 12 V reference 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

8. Replace the B119 Multi-axis Acceleration Sensor.

9. 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

10. All OK.
