5.7 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 only if
this test definition is present in the vehicle’s
computer memory. If no such definition is present,
the scan tool will just 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 will determine if it is OK.
