Communication System Diagnostic Notes
Before proceeding to the network index charts to diagnose a network DTC, review equipment level of vehicle. Make note of module and systems vehicle
is not equipped with. Before proceeding to a pinpoint test, make sure DTC being diagnosed is referencing a module or system which the vehicle is
equipped with. The New Generation Star (NGS) tester may produce a network DTC for no communication if the vehicle is not equipped with the suspect
module or system. The New Generation Star (NGS) tester will interpret a not equipped module as a communication failure. If a DTC is retrieved for a
not equipped module or system disregard this DTC. If a not equipped DTC is the only DTC retrieved the communication system self test should be
considered passed.
