TROUBLE DIAGNOSES WORK FLOWPFP:00004
When Displaying CAN Communication System ErrorsAKS00CBN
WHEN A MALFUNCTION IS DETECTED BY CAN COMMUNICATION SYSTEM

CAN communication line is open. (CAN H, CAN L, or both)

CAN communication line is shorted. (Ground, between CAN lines, or other harnesses)

The areas related to CAN communication of unit is malfunctioning.
WHEN A MALFUNCTION IS DETECTED EXCEPT CAN COMMUNICATION SYSTEM

Removal and installation of parts: When the units that perform CAN communication or the sensors related
to CAN communication are removed and installed, malfunction may be detected (or DTC other than CAN
communication may be detected).

Fuse blown out (removed): CAN communication of the unit may be stopped at such time.

Low voltage: If the voltage decreases because of battery discharge when IGN is ON, malfunction may be
detected by self-diagnosis according to the units.
