EOBD Application
17
Menu options
Not all vehicle control modules will support all of the options available from the menu.
If an option is not supported the service tool will display either “Not supported” or “Not
available”. This is a limitation of the software on the vehicle control modules and
NOT
a fault with the service tool.
MI Status/MIL Status
'MI Status' or 'MIL Status' displays the status of the malfunction indicator lamp for
each emissions related control module. If the status of the MI is set to On, one or more
DTCs will be stored in the vehicle's control modules and the instrument panel MI will
be illuminated.
View DTCs
This option allows any 'Stored' or 'Continuous' emission related DTCs (Diagnostic
Trouble Codes) to be viewed. If any DTC is present, it will be displayed along with the
identity of the Control Module (CM) that registered the fault.
If more than one DTC is displayed, the required DTC can be selected by using the
and
keys. Press
to select the DTC and display the description of the code.
Dependent upon the DTC and the vehicle manufacturer, it may be necessary to select
the manufacturer and possibly also the model of the vehicle to enable the correct
description to be displayed. This setting will be retained while the service tool is being
used for EOBD operations but can be redefined or cleared under the 'Manufacturer'
menu option.
Erase DTCs
This option will clear
all
'Stored' and 'Continuous' emission related DTCs, clear
'Freeze Frame' DTCs and associated data, clear 'O2 Sensor Test' data, clear 'Non-
Continuous' test results and reset the status of the 'System Readiness' tests on the
control modules on the vehicle. The service tool will then perform a 'Read DTCs'
operation to verify that the DTCs have been erased.
Live Data
This option allows the user to view the current status of the emission system
components on the vehicle and can provide a quick way of telling if a component is
working correctly.
The list of components monitored under 'Live Data' can vary between manufacturers
and even between model.
