Non-Continuous Tests
The purpose of this function is to obtain test results for emission-related powertrain
components and systems that are not continuously tested. Certain tests are run only
once per drive cycle when the vehicle is within proper operating conditions. This
function reports the test results after a single drive cycle. The Non-Continuous Test
function is useful after a vehicle repair or after clearing the PCMs diagnostic informa-
tion. Test results reported by this function do not necessarily indicate a faulty compo-
nent or system. Examples of systems not continuously monitored are catalyst and
evaporative OBD II monitors.
To view the Non-Continuous Monitors test
results, select Non-Contin Test from the OBD II
Function Menu and press the ENTER key.
The OBD II System Tester will request the vehicle to transmit the test IDs for available
non-continuous tests and display them in a list. The vehicle manufacturer is respon-
sible to assign test IDs and component IDs to distinguish between the different
systems and components. Refer to vehicle service manuals for test IDs and definitions.
NOTE: If you get an Operating Error message, make sure the DLC adapter cable is
securely attached, and the ignition key is ON, then try again. If the problem
remains, refer to Section 4: On-Line Help and Trouble-Shooting Tips.
Select a test ($xx) from the list then press the
ENTER key. Selected test results are re-
quested by the OBD II System Tester may also
include test limits. Only one test limit is usually
included in a responses message and
displayed on the screen. The single limit could be either minimum or a maximum
test limit. The OBD II System Tester will display the test ID, system or component ID
the test measurement, specification and status.
The first line of the display will show the Non-
Continuous test that was selected using its ID
number. The ID column displays the system or
component ID number, refer to vehicle service
manual for ID definitions and explanations. A
column labeled MEAS will contain the measured data of the test. The test measure-
ment data is displayed in hexadecimal number format (a system based on 16 digits
where letters A through F represent the digits greater than 9. The specification
values for the system tested are found in SPEC column and displayed in hexadeci-
mal number format. The final column, STS (Status) information is calculated by the
OBD II System Tester using the measurement and specification data. The status can
be Low, High or OK, depending upon the measurements relationship to the specifi-
cation.
