OBD-II/EOBD Demonstration
The OBD-II/EOBD training program allows you to navigate through many functions
of OBD-II/EOBD, and displays vehicle data (PIDs) and trouble codes (captured
from actual vehicle) to simulate what you might see on an actual vehicle.
NOTE
The OBD-II/EOBD function allows you to access “generic” OBD-II/EOBD data
(data limited to emission related diagnostics only). The Scanner function
allows you to access vehicle specific systems, parameters and enhanced
diagnostics.
The following OBD-II/EOBD demonstrations are intended to be completed in
sequence:
1 - Start Communication / Vehicle Identification
2 - Check Monitors Complete This Cycle
3 - Display Current Data
4 - Display Trouble Codes
5 - Find Trouble Code and Drive Cycle Information
6 - Display and Save Freeze Frame Data
