4.7 Generic OBDII 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 OBDII/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 24 for details.
4.7.1 General Procedure
To access the OBDII/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 which
one the vehicle is using.
Protocol — when this option is selected, the screen opens a submenu
listing various protocols. A communications protocol is a standardized
way of data communication between an ECU and a diagnostic tool.
Global OBD may use several different communication protocols.
3. Select a specific protocol under the Protocol option. Wait for the OBDII
Diagnostic Menu to display.
