The scan tool allows access to the results of on-board diagnostic monitoring
tests for specific components/systems. The vehicle manufacturer is
responsible for assigning "Manufacturer Defined Test IDs" and Component
IDs for tests of different systems and components. The advanced feature of
this scan tool enables you to read the definition of an On-Board Diagnostic
Monitor ID.
NOTE
The scan tool will display a test definition if this definition is present in the
vehicle’s computer memory. If no such definition is present, the scan tool will
only display the Test IDs.
In this test, there are typically a minimum value, a maximum value, and a
current value for each monitor. By comparing the current value with the
minimum and maximum value, the scan tool determines if the components
and monitors are OK.
1) Use the UP/DOWN scroll button to select On-Board Mon. Test from
Diagnostic Menu and press the OK button.
2) Wait while the scan tool validates the PID MAP.
3) The scan tool will prompt you to select the vehicle make.
4) After you select the vehicle manufacturer, the scan tool displays the On-
Board Monitors test results for specific monitored systems.
