Generic OBD II Operations
This option presents a quick way to check for DTCs, isolate the cause of an
illuminated malfunction indicator lamp (MIL), check monitor status prior to
emissions certification testing, verify repairs, and perform a number of other
services that are emissions-related. The OBD direct access option is also
used for testing OBD II/EOBD compliant vehicles that are not included in the
Diagnostics database.
The diagnostics toolbar buttons at the top of the screen are the same as
those available for specific vehicle diagnostics. See Table 4-2 Diagnostics
Toolbar Buttons on page 25 for details.
General Procedure
 To access the OBD II/EOBD diagnostics functions
1. Tap the Diagnostics application button from the MaxiCOM Job
Menu. The Vehicle Menu displays.
2. Tap the EOBD button. There are two options to establish
communication with the vehicle.
 Auto Scan – when this option is selected, the diagnostic tool
attempts to establish communication using each protocol in
order to determine the one from which the vehicle is
broadcasting.
 Protocol – when this option is selected, the screen opens a
sub menu listing various protocols. A communication protocol
is a standardized way of data communication between an
ECM and a diagnostic tool. Global OBD may use several
different communication protocols.
3. Select a specific protocol under the Protocol option. Wait for the
OBD II Diagnostic Menu to display.
