Circuit/System DescriptionThe 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 DTCIgnition ON Conditions for Setting the DTCC0186 4BThe lateral acceleration sensor is not calibrated. C0186 5AThe lateral acceleration sensor signal is not plausible with the yaw rate sensor signal, steering angle sensor signal and vehicle speed for 0.5-2 seconds. C0186 71The lateral acceleration sensor signal offset is out of specified range. C018B 5AThe lateral acceleration sensor signal is out of specified range C0196 00The yaw rate sensor signal is out of specified range. C0196 5AThe yaw rate sensor signal is not plausible with the lateral acceleration sensor signal, steering angle sensor signal and vehicle speed. for 0.25-2 seconds C019B 5AThe yaw rate sensor signal is out of specified range. C0196 71The yaw rate sensor offset is out of specified range. C0287 4BThe longitudinal acceleration sensor is not calibrated. C0287 5AThe longitudinal acceleration sensor signal not plausible.
