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 the high speed controller area network (CAN) serial data circuit. 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
* No lateral acceleration sensor signal
* The lateral acceleration sensor signal is not plausible with the yaw rate sensor signal, steering angle sensor signal and vehicle speed.
* The lateral acceleration sensor offset is out of specified range.
C018B 5A
The lateral acceleration sensor signal is out of specified range.
C0196 00, or C0287 00
* No yaw rate sensor signal
* The yaw rate sensor signal is not plausible with the lateral acceleration sensor signal, steering angle sensor signal and vehicle speed.
* The yaw rate sensor offset is out of specified range.
C019B 5A
The yaw rate sensor signal is out of the specified range.
C0196 71, or C0287 71
The electronic brake control module has received invalid serial data from the multi-axis acceleration sensor.
C0287 4B
The longitudinal acceleration sensor is not calibrated.
C0287 5A
* No longitudinal acceleration sensor signal.
* The longitudinal acceleration sensor signal is not plausible with the vehicle acceleration.
* The longitudinal acceleration sensor offset is out of specified range.
C0297 4A
Invalid serial data received from multi-axis acceleration sensor.
Action Taken When the DTC Sets
* The traction control/stability control-active indicator turns ON.
* The electric brake control module disables the stability control and hill start assist for the duration of the ignition cycle.
Conditions for Clearing the DTC
* A current DTC clears when the diagnostic runs and passes.
* 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 minutes for all vehicle systems to power down.
5. Test for less than 10 ohm between the ground circuit terminal 6 and ground.
• If 10 ohm or greater
1. Ignition OFF.
2. Test for less than 2 ohm in the ground circuit end to end.
• If 2 ohm or greater, repair the open/high resistance in the circuit.
• If less than 2 ohm, repair the open/high resistance in the ground connection.
• If less than 10 ohm
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 ohm in the 12 V reference circuit end to end.
• If 2 ohm or greater, repair the open/high resistance in the circuit.
• If less than 2 ohm, 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.
