Pre-Programming Preparations:

I. Preliminary Requirements

1.Prepare a laptop pre-installed with OE software and ensure it has sufficient battery. Tip: Keep the laptop plugged into a power source throughout the programming process to prevent power loss and interruption.

2.Connect the laptop to a wired network, ensuring a download speed of at least 5 MB/s. Some ECU data files are large; high network latency or interruptions will directly cause programming failure.

3.Connect the vehicle to a dedicated voltage-stabilized power supply for programming, maintaining the voltage between 13.2V and 14.5V. Voltage fluctuations can lead to programming failure, so a stable power supply is essential.

4.Park the vehicle on a flat surface to prevent the risk of rolling. An uneven surface may cause accidents during the programming process.

II. Pre-Programming Checklist

5. Check if the ECU power and ground circuits are functioning normally. Confirm that the information of the ECU to be programmed exactly matches the current vehicle's ECU information.

6. If programming a refurbished ECU, strictly follow the manufacturer's operating guidelines. Some refurbished ECUs (e.g., anti-theft modules) cannot pass OEM software validation. Used ECUs may need to have their data wiped before use; otherwise, programming will fail.

7. It is highly recommended to use brand-new ECUs for programming, and a stabilized power supply must be connected during the process.

III. Programming Process Standards

8. During programming, carefully read the operation prompts within the OEM software and strictly follow the steps. Do not perform unauthorized operations.

IV. Troubleshooting Programming Failures

9. If programming fails, first check the vehicle's status and the connection of the diagnostic equipment.

10. If the status is normal, let the vehicle sleep for 30 minutes before retrying. Powering off or putting the vehicle to sleep can clear cached error data and improve the success rate of the retry.

11. If the instrument cluster fails to display information properly after a failed programming attempt, proceed directly with programming again. Do not disconnect the equipment or power supply, and do not turn off the ignition.

⚠️ Note: Please use brand-new ECUs whenever possible, and always connect a stabilized power supply during programming.

Programming Steps:

1.Take out the RLink device, connect it to the vehicle's OBD diagnostic port and the computer's USB port respectively, and ensure a secure connection.

​

2.Once the device is connected, launch the RLink Platform software. Verify the vehicle connection status through the platform's connection information, check if the drivers are downloaded, and select RLink Mode under the BENZ driver.
Note: Before using DTS software for programming, it is recommended to log in to your RLink Platform account to check for any software or firmware updates. If updates are available, please update them before proceeding with vehicle programming.

​

3.Double-click to open the DTS software.

​

4.Click on Temporary workspace.

​

5.Select the data storage path: benchi(C:) > ProgramData > softing > Diagnostic Tool Set > DTSProjects_Daimler > BR 117 > cbf. Once in the data location, select CBF file mode in the bottom right corner, and then choose the EZS 166.CBF file.
Note: For vehicles manufactured before 2018, programming can be performed without unlocking the gateway module.

​

6.Select MBCar_MBVan_CBF_DiagnosticCAN_V_02_02 and click Finish to enter the programming page

7.Select Quick Test and click Start to identify the ECU information.

​

8.Click Diagnostic Services, then click EZS166 (HSCAN_UDS_500) to activate the EZS.

​

9.Select Variant Coding and click Connect to activate the coding status.

​

10.Click Save to back up the factory coding data.

​

11.Find and select [002] Globale Variantenkodierung.

​

12.Find Forward collision warning and disable its activation status.

​

13.After disabling the activation status, click Do Coding to execute the coding.

​

14.Once the coding is complete, click Disconnect to disconnect the coding session.

​

15.Select Diagnostic Services, find the EZS module, double-click [11] Hard Reset to perform an ECU reset. After the reset, enter XENTRY to perform a vehicle diagnostic check to see if the fault still exists.
