Quizplus · Accepted Answer

Technician A is correct because both PID (Parameter Identification) on J1587 and SPN (Suspect Parameter Number) on J1939 serve similar purposes in identifying specific parameters in vehicle diagnostic systems. Technician B is also correct because on J1939, every Diagnostic Trouble Code (DTC) is indeed tagged with an OC (Occurrence Count), which indicates how many times the fault has occurred.
