2. Pinpoint possible trouble spot according to diagnostic trouble code
If diagnostic trouble code related to CAN communication is set as past trouble, isolate opens as described below.
NOTE:
-
If you pinpoint trouble spot according to diagnostic trouble code, you should use time-out diagnostic trouble code. Diagnostic trouble code
related to failure information is set when the data to be set contains an error, so CAN bus line itself is probably normal.
-
Time-out diagnostic trouble codes are stored in each ECU memory individually. Therefore, it is possible that these diagnostic trouble codes
have not been set simultaneously. If the trouble spot cannot be found when you diagnose by judging from multiple diagnostic trouble codes,
check the communication lines between each ECU.
