OBD II PID Data Monitor

DESCRIPTION
The Parameter Identification (PID) monitor for OBD II offers real time evaluation of several emissions-related parameters. Most of these are related to the HO2S and EGR, for which the diesel has no equivalent. The only parameters which apply to 7.3L diesel applications are CCNT, IAT, LOAD, MAP, MIL, RPM and VSS.

NOTE: This procedure is written assuming the use of a New Generation STAR (NGS) Tester. If a generic OBD II scan tool is used, it will be necessary to follow the instructions supplied by the manufacturer of the scan tool.
