Tech 2 Data Definitions and Ranges Part 1
Engine Scan Tool Data ListUse the scan tool data listed in the table for comparison after the On-Board Diagnostic system check and finding the on-board diagnostics function properly with no diagnostic codes displayed. Not all parameters will apply to each vehicle. Use only the parameters which apply to your particular vehicle.
The Typical Scan Tool Data Values are an average of display values recorded from normally operating vehicles. The Typical Scan Tool Data Values are intended to represent what a normally functioning system would display. The values you get may vary due to a low battery charge or other reasons. But they should be very close.
Do not use a scan tool that displays erroneous data. Report the problem to the manufacturer. The use of a faulty scan tool can result in misdiagnosis and unnecessary parts replacement.
Use only the parameters listed in the tables for diagnosis. If a scan tool reads other parameters, the values are not recommended by Isuzu for use in diagnosis. For more description on the values and the use of the scan tool diagnosis the VCM inputs, refer to the applicable reference information listed. If all values are within the typical range described, refer to the Diagnosis By Symptom for diagnosis.
