SPN

SPN (Suspect Parameter Number) — A unit of information in S6. Each SPN has a name, ID number, data length, data type, and numerical value. SPN types include Parameters, Counters, and Events. An SPN may also include a specifier — an additional field used to refine the value of a parameter (for example: Total Fuel Consumption / Idle Mode, Report Transmission / Roaming, Battery Voltage Limit / Minimum).
