Technician A is correct that a scan tool is used to access the central gateway module for CAN bus diagnostics. However, Technician B is incorrect that if the scan tool can communicate with the central gateway module, then the CAN C circuit is at fault. There are multiple components and circuits involved in the CAN bus network, and a diagnosis should not be based solely on the ability to communicate with the central gateway module.
