5.2. How Are SMR-D Files Used in the Diagnostic Process?

SMR-D files are used in the diagnostic process to guide DTS Monaco in communicating with specific ECUs. When a technician selects an ECU for diagnostics or car coding, DTS Monaco loads the corresponding SMR-D file, which provides the necessary information for establishing a connection, sending diagnostic requests, and interpreting the responses from the ECU. This ensures that the diagnostic process is accurate and tailored to the specific ECU being analyzed.

6. How Does DTS Monaco Handle Security Access and Firewalls?

DTS Monaco handles security access and firewalls by implementing security protocols that require authentication and authorization before allowing access to protected ECU functions, and technicians often need to “defeat the firewall” before they can perform any variant coding. It supports various security access levels and methods to ensure that only authorized personnel can perform sensitive operations such as car coding and programming. The method to defeat the firewalls in place varies based on model year, and opening up the firewall is possible via the EZS167 ECU or the BCMFA2 ECU.

Defeating the firewall

6.1. What Security Protocols Are Supported by DTS Monaco?

DTS Monaco supports a range of security protocols, including:

• Security Access Level 37: Used in older vans to disable the firewall via the BCMFA2 ECU.
• Security Access Level 3B: Used in newer vans to disable the firewall via the EZS167 ECU.
• Seed-Key Algorithms: These algorithms require the diagnostic tool to request a seed from the ECU and then calculate a key to unlock access.
• MAC (Message Authentication Code): Used to verify the integrity and authenticity of diagnostic messages.
• Digital Signatures: Used to ensure that software updates and car coding data are from a trusted source and have not been tampered with.

6.2. How Does DTS Monaco Bypass or Authenticate Through Vehicle Firewalls?

DTS Monaco bypasses or authenticates through vehicle firewalls by using specific security access levels and authentication procedures defined by the vehicle manufacturer. The software first attempts to establish a secure connection with the ECU by requesting a seed value. It then uses a proprietary algorithm to calculate the corresponding key, which is sent back to the ECU for verification. If the key is accepted, the firewall is bypassed, and the diagnostic session can proceed. This process ensures that only authorized tools and personnel can access sensitive ECU functions.

9. How to Perform Variant Coding with DTS Monaco

To perform variant coding using DTS Monaco, the first step is to 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 car coding.

Extended Start

Then, 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. This is where the functions of the ECU can be accessed and is where you will actually find the values to change. After finding 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. Once everything looks good, press the “Do Coding”.

Do Coding

9.1. Step-by-Step Guide to Variant Coding

Here’s a step-by-step guide to variant coding:

1. Open the 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: Select “Extended Start” and press Transmit in the new ECU tab you opened up.
3. Go to Variant Coding Tab: Go to the “Variant Coding” tab and select your ECU.
4. Select Domain: Underneath the ECU you will see the “Domain” list.
5. Select Feature in Fragment Column: Find the relevant feature in the “Fragment” column
6. Select New Value: 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
7. Do Coding: Once everything looks good, press the “Do Coding”.
8. Make Coding Values Permanent: Synchronize to Non-volatile Memory Start, Synchronize to Non-volatile Memory Results, and perform a Hard Reset of your ECU.

9.2. Common Errors and Troubleshooting Tips During Variant Coding
