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.
