On-Board Monitor Test
The On-Board Monitor Test is useful after servicing or after erasing a
vehicle’s control module memory. The On-Board Monitor Test for
non-CAN-equipped vehicles retrieves and displays test results for
emission-related power train components and systems that are not
continuously monitored. The On-Board Monitor Test for CAN-equipped
vehicles retrieves and displays test results for emission-related power train
components and systems that are and are not continuously monitored.
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 test 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.
