ADVANCED OBD II FUNCTIONS
Press 9 to select <ADVANCED OBD II> from the <OBD II FUNCTIONS> menu.
<ADVANCED OBD II> functions are operating modes which may not be supported on
the vehicle. An <ADVANCED OBD II> menu is displayed, allowing you to choose
between the <ON-BOARD TESTS> mode and the <EVAP LEAK TEST> mode.
ON-BOARD TESTS
Press 1 from <ADVANCED OBD II FUNCTIONS> menu to select <ON-BOARD
TESTS>. The <ON-BOARD TESTS> mode provides the capability to examine the results
of various additional tests performed by the vehicle's controller(s). These tests are specific
to the vehicle manufacturer. The test results should be evaluated by referencing the vehicle
service manual. Two types of on-board test monitoring are supported: Non-Continuous
and Continuous.
NON-CONTINUOUS TEST RESULTS
Press 1 from the <ON-BOARD TESTS> menu to select <NON-CONTINUOUS
TESTS>. <NON-CONTINUOUS TESTS> is similar to the <O2S Test Results>. Some
manufacturers use this mode as an alternate for reporting O2 sensor test results. Non-
Continuous Tests are also referred to as OBD II Mode 6.
If the vehicle contains more than one OBD II ECU, select the primary ECU for the display
of diagnostic information. Refer to Section 5.0 Displaying Data For Multiple ECUs on
page 299, for more information.
In this mode the vehicle's controller reports data for various Test IDs (TIDs) and
Component IDs (CIDs). In addition to reporting data for these TIDs and CIDs, the vehicle
reports test limits (minimum, maximum, or both) for acceptable operation. The Tester
compares the data with the test limits and displays a PASS or FAIL indication for each
TID and CID. Please refer to the service manual for more information.
