2.2 ECU Selection and Firewall Deactivation

1. Identify the ECU: In the DTS Monaco workspace, you will see a list of logical links representing the ECUs in the vehicle. Select the ECU related to the engine or transmission you want to code. This might be the Engine Control Unit (ECU) or the Transmission Control Unit (TCU).
2. Open ECU in a New Tab: Right-click on the selected ECU and choose “New Tab for Logical Link”. This keeps the connection to the ECU open while you work.
3. Deactivate the Firewall: Before coding, you need to deactivate the ECU’s firewall. Go to “Generic Jobs” and select the appropriate security access level. This varies depending on the vehicle model and year.
   • Older Vans: Use “Security Access Level 37” via the BCMFA2 ECU.
   • Newer Vans: Use “Security Access Level 3B” via the EZS167 ECU.
4. Transmit the Security Access Request: Press the “Transmit” button. Ensure there is no red text in the response, indicating successful firewall deactivation.

2.3 Performing Variant Coding

1. Select Extended Start: In the new ECU tab, select “Extended Start” from the “Diagnostic Services” menu and press “Transmit”. This prepares the ECU for coding.
2. Navigate to Variant Coding: Go to the “Variant Coding” tab and select your ECU. If it’s not connected, press “Connect”.
3. Access the Domain List: Under the ECU, you will see the “Domain” list. This is where you can access the functions of the ECU and find the values to change.
4. Find the Relevant Feature: Select the appropriate domain related to the engine or transmission type. Look for the specific feature you want to modify in the “Fragment” column. For example, if you want to adjust the transmission shift points, you would look for a fragment related to “Shift Points” or “Gear Ratios.”
5. Modify the Value: Double-click the value under the “Meaning” column to open a dropdown menu. Select the new value you want. The original value is displayed under “Original Meaning.”
6. Review the Coding: Check the binary coding string under “Read from ECU” (current coding) and “Current Coding” (new coding). Ensure everything looks correct.
7. Do Coding: Press the “Do Coding” button. If everything is correct, the bar next to “Do Coding” will go to 100%, and the new value will be displayed under the “Meaning” column.

2.4 Making the Changes Permanent

1. Synchronize to Non-volatile Memory: Go back to the open tab with the ECU you just coded. In the “Diagnostic Services” search box, find and select “[31] Synchronize to Non-volatile Memory Start”. Click “Transmit” and ensure you get an “acknowledged” Response State.
2. Synchronize Results: Next, click “[31] Synchronize to Non-volatile Memory Results” and “Transmit”. Again, you should get an “acknowledged” Response State.
3. Perform a Hard Reset: Perform a hard reset of the ECU. Turn off the vehicle, open the driver’s door, wait a few minutes, and then turn the vehicle back on.
4. Verify the Changes: Log back into the ECU and check the values to ensure the changes have been applied.

2.5 Example: Coding for Different Engine Types

Let’s say you are working on a Mercedes-Benz Sprinter van, and you need to adjust the ECU settings for a diesel engine variant. Here’s how you would approach it:

1. ECU Selection: Select the Engine Control Unit (ECU) from the list of logical links. The specific name of the ECU might vary, but it will typically include “Engine” or “Motor.”
2. Variant Coding Domain: Navigate to the “Variant Coding” tab and find the domain related to engine parameters. This might include options for fuel injection, turbocharger settings, or emission controls.
3. Engine Type Parameter: Look for a parameter that specifies the engine type. This could be a dropdown menu with options like “Diesel,” “Gasoline,” or specific engine codes like “OM651” or “M274.”
4. Select the Correct Engine Type: Choose the engine type that matches the vehicle you are working on. This ensures the ECU uses the correct calibration and settings for that engine.
5. Apply Coding: Press “Do Coding” to apply the changes. Follow the steps to synchronize the changes to non-volatile memory and perform a hard reset.

2.6 Example: Coding for Different Transmission Types

Similarly, if you are coding for different transmission types, you would follow a similar process:
