6 EOBD
The OBD II/EOBD diagnosis is available to be downloaded through Mall. 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.
General Procedure
To access the OBD II/EOBD diagnostics functions
1. Tap the Diagnostics button on the main home screen. Tap No button to start
vehicle's EOBD diagnosis. 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 which
one the vehicle is broadcasting on.
Protocol – when this option is selected the screen opens a submenu of
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.
2. Select a specific protocol under the Protocol option. Wait for the OBD II
Diagnostic Menu to display.
3. Select a function option to continue.
