Operations Selecting a System
Selecting a System
Once you have confirmed a vehicle identification, the System List menu displays. This menu
shows all the systems available for testing.
z Note the following when selecting a system for testing:
• The terms “left” and “right” refer to separate engine bank control systems for 12-cylinder
engines and assume left and right from the position of a seated driver. OBD-II terminology
uses Bank 1 and Bank 2. The Scanner calls Bank 1 (cylinders 1–6) on the passenger side,
“(Right),” and Bank 2 (cylinders 7–12) on the driver's side, “(Left).”
• Bank 1 is controlled by ME 1 and Bank 2 is controlled by ME 2.
• For the V12 engine, long intake runners with a MAF sensor for each bank are located on the
opposite side of the engine.
• For those vehicles with multiple system choices, if the Scanner is not able to establish
communication using the first system choice, try again using an alternate system choice.
See “Appendix A Troubleshooting and Communication Problems” on page 98 for help trying
to establish communication.
Connecting to a Vehicle
After selecting from the System List, the Scanner displays a connection message that tells you
which adapter and personality key to use to connect the Scanner for testing. Each test adapter
plugs into a specific vehicle diagnostic connector and attaches to one end of the data cable. The
other end of the cable attaches to the Scanner. Captive screws secure both data cable ends.
The following adapters are available to connect the Scanner to Mercedes-Benz vehicles:
• MB-1—for the 38-pin underhood connector.
• MB-2A—for the 8-pin or 16-pin underhood connector.
• DL-16—for 1996 and later vehicles with an OBD-II style connector.
When available, it is recommended to use the underhood 38-pin connector for those vehicles
from approximately 1996–2001. For those vehicles with dual connectors, the under-dash 16-pin
may have limited functionality.
Use the following adapter + Personality Key™ combinations for the appropriate systems.
• DL16 + S4—KLA/TAU airco system (A/SLK-series)
• MB1 + S33—KLA/TAU airco system
• MB1 + S34—ZAE airbag, EWM (electronic gear selector) system
NOTE:
i When a CIS-E vehicle is identified, a connector message appears instructing you to use the
“MB-2 + 2.5 mm adapter cable” which is designed to be used in conjunction with the yellow lead
on the MB-2 adapter. This 2.5 mm adapter is currently not available in the Scanner accessory
package (many test lead kits may have a standard banana plug for the 2.5 mm adapter). On
CIS-E, a duty ratio test reads current faults via a duty-cycle output. The vehicle diagnostic
connector is a round 9-pin. Connect to pin 3 as directed by the display message.
