Global OBD II/MTS 3100 Mastertech
CLEAR DIAGNOSTIC INFORMATION
The Clear Diagnostic Information function is used to clear
DTCs from vehicle ECUs along with any other diagnostic
information that the controller has saved, such as Freeze
Frame Data and Readiness Test information. A prompt screen
is displayed to prevent inadvertent clearing of the diagnostic
information.
OBD CONTROLS
The OBD Controls mode enables an off-board device to
control the operation of an on-board system, test, or
component. The support of this test mode is completely
dependent on the vehicle under test.
OXYGEN SENSOR TEST RESULTS
The OBD II system can provide Oxygen Sensor (O2S) Test
Results for multiple oxygen sensors. The O2S Test Results
function queries the ECU to determine which oxygen sensors
are present. It displays a list of these sensors so you can select
one to examine. The MTS 3100 Mastertech then displays all
available parameters for the selected oxygen sensor.
ADDITIONAL TEST RESULTS
The Mastertech supports additional on-board test results that
are specific to the vehicle manufacturer. If supported, these
tests can provide a pass/fail status of many tests run by the
OBD II controller. Test definition can be obtained by the
manufacturer.
READINESS TESTS
The Readiness Test function allows you to monitor the status
of various on-board tests that are performed by vehicle ECUs.
These tests must run for the DTC and Test Results displays
to accurately reflect the health of the vehicle's emissions-
related components. This function indicates which tests are
complete, incomplete, or not available (N/A) for the vehicle
being tested.
INFORMATION
The Information mode displays identification information
provided by the vehicle's OBD II controller. Information
can include the VIN, Calibration ID which uniquely
identifies the ECU software, and Calibration Verification
Number which determines if emission calibrations in the
ECU have been altered.
You can clear all
emissions-related
DTCs and other
diagnostic
information from
all OBD II
controllers.
