22. How to Defeat the Firewall(s) in DTS Monaco?

Before you can start doing any variant coding in DTS Monaco, you need to defeat a firewall. Softing, who created DTS Monaco, presumably put these in place to ensure that only Real Professionals can work on your vehicle. What firewalls are in place varies based on model year, etc.

Defeating Firewalls

• Older Vans: Log into the BCMFA2 ECU. In the list of logical links, right-click on EZS167 and select “New Tab for Logical Link”. In the new tab, go to “Generic Jobs” and select “Security Access Level 37”. Press the “Transmit” button and you should see a bunch of text in the window below. Provided that you see no text in red, in an older van, you should now have turned off the firewall.
• Newer Vans: The process is a little different and done via the EZS167 ECU instead. Do the same process as described above, but this time it’s “Security Access Level 3B”. Click “Transmit” and provided that you see no red text and have “acknowledged” displayed under “Response State”, your firewall should now be deactivated.

23. How to Perform Variant Coding in DTS Monaco?

Now, it is time to perform the actual variant coding. Open up the relevant ECU governing the features you want to change and open it in a new tab. Once done, you first want to select the “Extended Start” and press Transmit in the new ECU tab you opened up. Provided that you correctly disabled your firewall and still have the relevant ECU (EZS167 and/or BCMFA2) open in a tab, you should see another “acknowledged” Response State. The ECU is now ready for coding.

Steps to Variant Coding

1. Open Relevant ECU: Open up the relevant ECU governing the features you want to change and open it in a new tab.
2. Select Extended Start: Once done, you first want to select the “Extended Start” and press Transmit in the new ECU tab you opened up
3. Variant Coding Tab: Go to the “Variant Coding” tab and select your ECU. It should connect – if not, press “Connect”. Underneath the ECU you will see the “Domain” list.
4. Select Domain: Select the “Domain” list where the functions of the ECU can be accessed and is where you will actually find the values to change.
5. Find Relevant Feature: Find the relevant feature in the “Fragment” column. Double-click the value under “Meaning” (this is what you’ll change it to) and a dropdown menu will open up – select the new value you want.
6. Do Coding: Once everything looks good, press the “Do Coding”.

Variant Coding Tab in DTS Monaco

24. How to Make New Variant Coding Values Permanent in DTS Monaco?

In older vans, a “Hard Reset” of your ECU should be sufficient to make your coding changes permanent, however, for newer vans, you need to go through a few more steps, so let’s do that first.

Steps to Make Coding Permanent

1. Synchronize to Non-volatile Memory Start: Click back to the open tab with the ECU you just changed variant coding for. In the “Diagnostic Services” search box, first find the “[31] Synchronize to Non-volatile Memory Start”. Click Transmit, and provided everything upstream was done correctly, you should get an “acknowledged” Response State and no red text.
2. Synchronize to Non-volatile Memory Results: Next, click “[31] Synchronize to Non-volatile Memory Results”, followed by Transmit. Again, you should get an “acknowledged” Response State.
3. Hard Reset of your ECU: Now, it’s time to perform the Hard Reset of your ECU.
4. Final Check: Do a Hail Mary, turn off the van, open the driver’s door, wait a few minutes, do another Hail Mary, and provided that your van did blow up in flames, the changes should now be permanent! You can check that by turning on the van (engine off), logging into the relevant ECU and then checking.
