5 OperationsIdentifying the Vehicle
When multiple engine choices are listed, only the correct engine choice communicates with the
Scanner. If the Scanner does not communicate after selecting one engine, select the other
engine and try again. Always scroll to verify if any additional engine choices are available.
Multiple engine systems are sometimes listed together as one selection (for example HFM/ME2)
because vehicle systems may vary depending on country. The Scanner automatically identifies
the correct system.
If you pressed N from the Current Vehicle Identification screen, the following menu displays
Figure 3-1 Software Selection menu
Selecting System ID mode allows the user to go to the selected system and control unit. The
scan tool displays a list of systems or modules with which the scan tool can communicate.
iThe list of systems or modules that the scan tool can communicate with is not customized to the

6 OperationsIdentifying the Vehicle
Selecting a module that is not fitted to the vehicle will result in a “No Communication” error
message. Some systems will list the same systems or modules more than once; the correct
choice is the only one that will communicate with the scan tool.
zTo identify a vehicle:
1. Press Y to continue.
The Mode Selection menu displays.
2. Scroll to Vehicle Selection and press Y.
The following screen displays (Figure 3-2).
Figure 3-2 Sample Vehicle ID screen
3. Scroll to select the required model series and press Y.
iThe Scanner indicates those vehicles not available to the United States market by displaying “not
available” after the US VIN.
The display now shows the model series you selected and asks for the model number for the
Figure 3-3 Sample Vehicle ID screen
4. Scroll and press Y to select the model number.
The display now shows the selected model series and model number and requests the
Figure 3-4 Sample Vehicle ID screen
The Scanner displays only those model years available with the selected model.
5. Scroll and press Y to select the model year.
The display now shows the selected model series, model number, and the model year and
asks for the engine type.

7 OperationsSelecting a System
Figure 3-5 Sample Vehicle ID screen
After engine displacement, the Scanner indicates engine mount, type, and number of
cylinders. For example:
–L-V8: Engine mounted in-line, V-type, 8 cylinders
–L-L6: Engine mounted in-line, in-line type, 6 cylinders
The Scanner only displays those engines available with the selected model and model year
combination. Typically, only one engine type exists for each model and model year
6. Scroll to select the engine type and press Y.
The Scanner now displays the Vehicle ID Confirmation screen.

7. If the identification is correct, press Y to store the identification in memory and continue. If
the identification is not completely correct, press N to return to the start of the identification
Selecting a System
Once you have confirmed a vehicle identification (see previous section), the System List menu
displays all the ECUs in the vehicle along with a brief description.
Figure 3-7 Sample System List screen
zNote 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.

8 OperationsConnecting to a Vehicle
•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 110 for help trying
to establish communication.
zTo select a system for testing:
•Scroll to the system you would like to test and press Y.

Connecting to a Vehicle
After selecting the required system from the System List, the Scanner displays a connection
message. This screen tells you which adapter and personality key to use to connect the Scanner
Figure 3-9 Sample Scanner connection message
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

9 OperationsConnecting to a Vehicle
iWhen 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.
Each test adapter connects to one of the following vehicle diagnostic connectors.
