Step-by-Step Connection Guide

Now that you have verified the necessary requirements, follow these steps to connect your Topdon RLink device with GM Techline Connect:

Step 1: Install & Update RLink Suite

Step 2: Install J2534 Driver

1. In RLink Suite, go to “Driver Management.”
2. Remove any unnecessary drivers, such as those for Chrysler, since one system only accepts one software driver.
3. Install the GM-specific J2534 driver by navigating to “Driver Download.”
4. Once installed, verify the installation under “Driver Info” and ensure that only GM drivers are present.

Step 3: Launch GM Techline Connect

1. Right-click on the GM Techline Connect browser icon and run it as an administrator. This step is crucial for ensuring that the software can perform necessary updates.
2. Log in to GM’s Service Information Website. If you don’t have a Techline Connect license, you will need to purchase one.
3. After logging in, right-click on Techline Connect (TLC) and run it as an Administrator. You may need to relaunch the software again with admin privileges.

Step 4: Check for Software Updates

Upon logging into TLC, the software will automatically check for updates. Ensure that the SPS2 (Service Programming System 2) is fully updated. Once updates are completed, you should see the main TLC screen.

Step 5: Connect RLink and Techline Connect

1. Close any Vehicle Selection windows for now.
2. To configure automatically, click on the options below:
• Auto Detect Tool
• Auto Detect VIN
3. Select the J2534 adapter. If the Auto Detect fails, manually search for the RLink.
4. Under “Reprogram” mode, select J2534.
5. Choose “RLink” from the device list and click “Submit.”
6. Confirm the connection, and a window should appear showing available devices. Select RLink and click “Continue.”

Step 6: Verify Connection for Programming

If the connection is successful, the top-right corner of the screen should display “Diagnostic Tool Ready – J2534.” You can then auto-detect the VIN if needed or proceed with module programming. Congratulations, you’ve successfully connected your Topdon RLink with GM Techline Connect!
