HINT:
-
CAN communication DTCs are stored when there is an open or short in any of the communication wires. Any problems with the power
source of a corresponding ECU or sensor, or problems in the ECU or the sensor itself also cause these DTCs to be stored.
-
If a CAN communication wire connector is disconnected with the ignition switch ON, the ECUs of the corresponding system and related
systems store a DTC.
