9.6 ERRORevents (CANbus)

9.6.1 Introduction

A diagnostic error is logged every time the periodic diagnostic functions detect a coming or going fault on the CAN

bus communication.

Depending on the communication bus side, the logged source can be the control unit or a single sensor.

9.6.2 CAN errors (CANERROR)

Error Meaning

TIMEOUT Timeout on message to sensor/control unit

CROSS CHECK Two redundant messages do not coincide

SEQUENCE NUMBER Message with sequence number different from the expected number

CRC CHECK Packet control code does not match

COMMUNICATION

LOST

Impossible to communicate with the sensor

PROTOCOL ERROR Control unit and sensors have different and incompatible firmware versions

POLLING TIMEOUT Timeout on data polling

NOTICE: A shielded cable between the control unit and the first sensor, and between the sensors is strongly

recommended. Nevertheless, route the CAN cables separately from high-potential power lines or through an

exclusive conduit.
