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 function the same
as those available for specific vehicle diagnostics. See Table 4- 2
Diagnostics Toolbar Buttons on page 27 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.
