DTC C0287 5A

- Longitudinal Acceleration Sensor Circuit Not Plausible

DTC C0287 71

- Longitudinal Acceleration Sensor Circuit Invalid Data

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 (EBCM). The EBCM supplies a 12 V reference voltage to the multi-axis acceleration sensor. The multi-axis

acceleration sensor communicates with the EBCM via the high speed controller area network (CAN) serial data circuit. The EBCM activates the

stability control function depending on multi-axis acceleration sensor input.

Conditions for Running the DTC

Ignition ON

Conditions for Setting the DTC

C0186 5A

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

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

C0186 71

The EBCM received an invalid lateral acceleration sensor signal.

C0196 00

The yaw rate sensor signal is not plausible.

C0196 5A

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

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

C019B 5A

The yaw rate sensor signal is out of specified range.

C0287 4B

The longitudinal acceleration sensor signal offset is out of specified range.

C0287 5A

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

C0287 71

The EBCM received an invalid longitudinal acceleration sensor signal.

Action Taken When the DTC Sets

C0186 5A, C0186 71, C0196 00, C0196 5A, and C019B 5A

* The EBCM disables the stability control for the duration of the ignition cycle.

* The traction control/stability control-active indicator turns ON.
