TOPDON RLink J2534 Pass-Thru Programmer, OEM Reprogramming and Diagnostic Tool, Enhanced J2534 VCI, Supports J2534/D-PDU/CAN-FD/DoIP, Compatible with 18+ Vehicle Brands, No OE Software Provided

Was able to program my Infiniti G35 Transmission Control Module with ease using the Rlink. Also was able to write Vin code to used ECU for same car. Compatible with many different makes of cars. Simple install of drivers and the software is very easy to navigate. Works great with Consult 3+ RTR and NERS (Nissan ECU Reprogramming Service) Vers. 3.08 offline. Also works on or offline for Consult 3+ also! The navigation of app is very easy to follow. I saw a cpl ppl on auto forums mentioned that the programming speed was a lil slow but I saw no issues with that. Everything went pretty smooth and that was the first time I had ever reprogrammed any automotive ECU/TCM. Oh and the quality of the dongle and the cable r Topnotch and comes in a very nice zip up pouch with lots of cushionning to protect it if u happen to drop case or anything. Definitely would recommend getting one if u need to program any of ur vehicles computers. Works great for diagnostics as well, clearing codes, basically anything that u need to do to ur vehicle that includes connecting to OBD2 port.

Set-up was pretty simple following the instructions in the computer software. I have used it for GM vehicles is the factory GDS software and on a few Ford vehicles with the aftermarket FORScan software, and it works great with the appropriate driver installed. It is powered up when connected to USB so it doesn't require a vehicle available for initial settings to be configured. Communication with the Ford and GM vehicles seems just as fast if not faster than the OEM devices I've used previously. I've been told by another user it is actually more reliable than the OEM device for GM in his shop Connecting to my phone was easy with the topscan app, but I have really used it yet. Bluetooth siggnal seem more than adequate for use as a scanner. This is a great feature that I don't think most other j2534 devices offer. The build quality seems good and is an excellent value being able to use it for more than one manufacturer for less than the cost of any other brand name interface I looked at.

I work at a car dealership. I thought there was no way this thing would work with our software. I have been proven wrong. And it cost me a quarter of what it would have cost to buy one from the manufacturer. So far I've pulled codes, checked onboard snapshots, and programmed a key with it. And now that I've got my own pass thru device I don't have to fight other technicians for the limited resources available at the shop - we only had 2, 3 if you count the one that is out of date and no longer supported. Needless to say it's improved my workflow. Honda, for the record.

Fantastic. The rlink is great. It’s your manufactures program that may suck lol like ours (GM). Worked perfect to check codes on gmc 2007 Yukon, fix issue and clear codes. Just buy it. I did have to uninstall the gm drivers through rlink software then reinstall for Tech2win to register the instance

Amazing J2534 device. Fixed my PCM when the factory one couldn't. Works extreamly well for Stellantis peoducts using witech2 diagnostics software. A little background: My 2025 Ram 1500 got its PCM (ECM) corrupted due to a loss of communication during a flash/cali ration using the Factory Witech2 certified POD. I tried many times to bring it back and it would not work. Took the PCM to a "specialist" and was told my device was bricked and needed a new one. So, I purchased a new PCM and while updating the flash on my brand new PCM, same issue. So, at this point I concluded the issue was the tool I was using. Found this TOPDON RLink J2534 on amazon, did a little research and found it to be compatible. Once I got it, I configured it to my laptop and was able to flash my brand new PCM without issues. I decided to try and flash my original unit and with the help of this device I was able to bring it back. So, now my truck works flawlessly, no DTCs and all ECUs are updated thx to this device. The driver management thru the Topdon Rlink App is amazing. So easy to configure and use. For the price it is imposible to do better. Highly recommended for Stellantis vehicles.

I needed to reprogram a body control module on a 2006 Pontiac Grand Prix to enable heated seats and remote start. This required a combination of SPS2 and Tech2Win through Techline Connect. I initially was between the TOPDON's Rlink and XTOOL's XTS500. I first purchased XTOOL's XTS500 since I've used their products before, and it was cheaper. Turns out it was the worst mistake I could have made. It was a week of headaches just trying to get it to work, and I ultimately decided to return it because it was a complete dud. At this point, I still needed to program the BCM, so I decided to buy TOPDON's Rlink. This product worked quite seamlessly. The software was straightforward and easy to use. I downloaded the necessary drivers, and everything just worked. SPS2 had no issues identifying and updating modules. Tech2Win was able to detect the Rlink with no problem. The best part is that the Rlink is powered through USB-C, so you can get everything set up before heading out to the car. As my only other exposure to pass-thru programmers was the XTOOL's XTS500, this was an amazing feature. Overall, if you need a reliable pass-through programmer for GM products, go ahead and purchase this. The entire experience is straightforward, and I have no complaints about this product. Honestly, this is probably the best product on the market at this price range.
