Please answer me:
1. What is the difference between CAN Node ID & CAN Message ID? How the CAN Node ID helpful in Communication?
Is it possible that one ECU will request another ECU for diagnostic data using Services? I think it is not possible. Tester needs to send Diag services for diagnosing the ECU. One ECU can't diagnose other ECU.
Please let me know does CAN ID '0' is valid or not?
