Parameters Identifiers, or PIDs, are numbers and names used to identify data being displayed. So think if PIDs in terms of “readings” such as oil temperature, coolant level, engine RPMs, and so on. PID is a J1708 term, and then SPN is a J1939 term. If you compared a list of PIDs to SPNs, you would notice two things.Detroit DD15 EPA10 (2010-13) Fault Code: SPN 1231 FMI 9 (MCM) Aftertreatment Control Module Message Not Received or Has Stopped Arriving.
