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 26 for details.
General Procedure
To access the OBD II/EOBD diagnostics functions
1. Tap the
Diagnostics
application button from the MaxiDAS 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.
