Screen printing Description
V1.2 Micro-controller power supply voltage
V1.8 Internal chip power supply voltage (1.8 V)
V1 Internal chip power supply voltage (1 V)
7.5.6 Anti-tampering sensor (TAMPERERROR)
Error Meaning
TILTANGLEERROR Sensor inclination around the x-axes
ROLLANGLE ERROR Sensor inclination around the z-axes
PANANGLE ERROR Sensor inclination around the y-axes
Note: an information in degree related to the angle is reported.
7.5.7 Signal error (SIGNAL ERROR)
The signal error occurs when the sensor detected an error in the RF signals part, in particular:
Error Meaning
MASKING The sensor is obstructed;
MASKINGREFERENCEMISSING During the configuration process, it was not possible to get the masking
reference.
SIGNALPATTERNERROR Radar internal fault or unexpected signal pattern
7.5.8 Temperature errors (TEMPERATUREERROR)
Error Meaning
BOARD TEMPERATURE TOOLOW Board temperature below minimum
BOARD TEMPERATURETOOHIGH Board temperature above maximum
CHIP TEMPERATURE TOO LOW Internal chip below minimum
CHIP TEMPERATURE TOO HIGH Internal chip above maximum
IMU TEMPERATURE TOO LOW IMU below minimum
IMU TEMPERATURE TOO HIGH IMU above maximum
7.5.9 MSS error and DSS error (MSS ERROR/DSS ERROR)
Error detected by diagnostics relative to the internal micro-controllers (MSS and DSS), their internal peripherals
or memories
7.6 ERRORevents (CANbus)
7.6.1 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.
7.6.2 CAN errors (CANERROR)
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
