Introduction

I have decided to rebuild and update the DTC2 executable version into a browser-based application. DTC2 is now fully web-based and can be accessed directly through the browser, offering greater flexibility and easier access from various devices. The main functions remain the same as in the DTC.exe version. The new version is called DTC2 Online.

What is DTC2 online

DTC2 online is an application for deactivating or deleting DTCs from an ECU Flash Dump. It allows you to remove individual error codes from the ECU. Additionally, the software includes a function to export DTCs from MEDC17, EDC16, MED9, ME7, and MDG1 to an A2L file, which can be used in other software like WinOLS, etc. Furthermore, it has a comparison function that enables you to compare two files. There are also updates and new solutions.

Why DTC2 is now Web-based

The problem with DTC2.exe is that it has grown larger than expected, making it difficult to maintain the software for all users. Additionally, users can sometimes be very challenging. I strive to answer all support questions, but it can sometimes take a few days. During this time, some users send multiple emails, which can be overwhelming. DTC2 online has a very good file identification system, which should eliminate the first user errors. If a file does not work, it is not possible to open a ticket manually. In the past, multiple tickets were opened for the same file. Now, the software automatically creates a ticket, allowing me to see and fix any issues more efficiently.

There are also Updates and new Solutions you can find Infos about it in the News section.

Also such problems like:

• HW-ID changes when an external HDD is connected.
• DTC2 is incompatible with virtual machines.
• DTC2 does not function on Windows ARM systems.
• DTC2 is not supported on Windows XP (seriously!).
• Is detected as Virus!?

I am aware that the new version has some drawbacks. For example, the biggest issue for me personally is that DTC OFF files are always saved in the browser's default download folder. Unfortunately, I cannot change the destination where the files are stored. Strangely, several users have pointed out to me that they now always need an internet connection, but that was already the case with the DTC2 executable.

But now, let's move on to the advantages:

• You can now use DTC2 on any device that has a modern web browser.
• The speed! Anyone who has worked with a VAG MED17.x on DTC2 knows it could take about 5 minutes to find DTCs. Now, it takes just 10 seconds.
• Updates are much easier to implement.

What browser do I need? I testted DTC2 online with the following browsers:

• Google Chrome
• Mozilla Firefox
• Microsoft Edge

How it works

You can use the same login data as in DTC2.exe. If you don't have an account, you can create one here. After that, you need a valid license to use the software. Then you can start uploading your file and begin working with it.

How do I get a license? Users with a DTC2.exe license can now import their license into DTC2 online. New licenses and renewals are available in the webshop.

Is there no HW-ID anymore? Yes, the HW-ID is no longer needed. Can I share my account with all my friends? No, the account is still personal and can only be used simultaneously for the number of HW-IDs you have. For example, if you had 2 HW-IDs, you can be logged in with 2 sessions. If a third login occurs with this account, the oldest session will be canceled. Additionally, if you share your account, it will be blocked ;).

What does "2 sessions" mean exactly? You can use DTC2 online on two devices at the same time. If you log in on a third device, the oldest session will be automatically terminated.

FAQ

What is DTC2 online?

DTC2 online is an application for deactivating or deleting DTCs from an ECU Flash Dump. It allows you to remove individual error codes from the ECU.

How do I get a license?

Old DTC2.exe users can import their license from the old DTC2.exe (Look at the Main Page). All users, new and old can buy a license in the Webshop soon (End January 2025).

Is it possible to use the old DTC2.exe?

Simple: NO! The old DTC2.exe is no longer supported. The new version is DTC2 online it will fully replace DTC2.exe.

My file is not working, what can I do?

If the ECU is on the supported ECU's List, you can open a ticket. If not, you can't use the software. Non-working files are also sent automatically to me, and I will look at them when I have time.

What do you do with my uploaded files.

Indeed, it's a good question. But no worries, this is not a file collecting software. You can see your uploaded files in the DTC2 online file history. I have many users with many files, so I don't have much space to store files permanently. Therefore, after a minimum of 6 hours, the files are deleted.

My TIP: If you have such a unique tune/solution that nobody should see, I am sure you are able to do the DTC OFF by yourself!

I don't found DTC PXXXX

In ECU you can only deactivate ECU Errors!!! No ABS, BCM, Light etc. Errors (Yes from time to time I get such questions)

Some ECUs have a "slave" module most time Adblue ECU like DCU17CPXX what have a own DTC table! So you read AdBlue DTCs from the ECU but cant find them in DTC2 Software. So if you make AdBlue off pay attention to the correct application of the solution if there is somthing like "diconect Adblue Modul".

On VAG and VCDS don't always believe the DTC description. Also deactivate the MAN Code.
Example:
16619 - Ladedruckregelung
P0235 - 000 - Regelgrenze unterschritten

If you don't found P0235 search for 16619.

On BMW DTC Codes often displayed with 3 Bytes, search only first 2 Bytes:
Example:
12BB01 - Oxygen Sensor After Catalytic Convertor

12BB01 dont't found search for 12BB.

Status   OFF   but via Diag DTC still there.

There can be many reasons for this, but in most cases, this is how it behaves.

Sometimes it is not entirely clear whether DTC is ON or OFF. For example, DTC2 Online only checks the path, not the disable mask. Also, do not always rely solely on whether it is marked as ON or OFF. Turn off the DTC anyway and test the file.

Correct DTC2 online the Checksum?

NO! DTC2 online doesn't correct any checksums. You need to do it by yourself with WinOLS or like in most cases your flashing tool makes the checksum.

What can i do when DTC found in my original file but not in my moded file?

You need to know whether the start or the end of any table has changed. It is not possible to find the correct pattern to identify a table with 100% accuracy in every file. Fortunately, I added a feature that allows you to upload the original file after a modified file was not detected correctly. Than the found offsets from the original file are used to search in the modified file.

WinOLS Solutions F7 Integration

💎 PRO Features

Some special protocols are available exclusively for PRO users. All CAR DTC protocols will be not affected now or in future. However, truck and agricultural ECUs often require unique solutions, so I decided to reserved this Protocolls for PRO users.

PRO features are included only with the two highest licenses: 3 sessions / 50 files per day and 4 sessions / 100 files per day. These are designed for professional users and provide access to advanced protocols for DTC removal on truck and agricultural ECUs. Many of these protocols are already in beta, and both current and future beta protocols will remain exclusive to PRO users. You can check the supported ECU list what protocols are available only for PRO users here.

You can download now where possible JSON Mappacs for WinOLS with the PRO License. It is the successor to the A2L export, but with more information and a better structure. You can import the JSON Mappack into WinOLS without a Plugin.Than you can easily find the DTCs in your file and also get more information about the DTCs. The JSON Mappack is only available for PRO users and only for some ECUs, but I will add more ECUs in future. You can check the supported ECU list what protocols are available only for PRO users here.

If you allready have a PRO license, you can use these special protocols without any additional steps. But if you have a normal license and want to use the PRO features, you need to upgrade your license. You can do this in the License Management section of your user panel.
