    • Very easy use and integration with Launch diagnostic unit!
Review Image by F. Morelli
The TSGUN is made for integration with a Launch diagnostic tool. In my case, I am using a Launch X431 Pro3S+. The two devices bind over bluetooth, and was quite straightforward. Once bound, one can perform a variety of TPMS functions using the TSGUN through the Launch X431 TPMS screen. Firmware upgrades are downloaded by the Launch scan tool and sent to the TSGUN, keeping it up to date. Functionally it is quite simple - select your country region, vehicle brand, and specific vehicle. Then pointing the TSGUN at the sensor, one can both read status of the sensor or program the sensor to the specific car. I wanted to show a specific case where there is a failed TPMS sensor. The BMW I was diagnosing had two TPMS error codes - one for the right rear wheel sensor, a second for the TPMS receiver antenna. It is not unusual to have an antenna error if all four sensors are not being read. Pointing the TSGUN to the right rear sensor, I attempted to code the sensor. After 20 second the TSGUN notified the Launch Pro3S+ that it failed to communicate to the right rear sensor. This confirmed that my issue was, in fact, a bad wheel sensor, which was one of four new HUF sensors that had been recently installed. The other sensors read just fine. If you have a Launch diagnostic tool, the TSGUN is a great addition. It is sturdy, well built, with simple and straightforward functionality. One or two diagnostic and reprogramming sessions pay for the tool. Tough to beat! ... show more

Great product. It's worth every cent. LAUNCH X431 TSGUN TPMS relearn tool can work well with my x431 v pro. I use it to check the condition of the tires and it will tell you the sensor ID, tires air temperature, battery level and pressure of each wheel. I purchased a new set of tires and rims with installed and balanced TPMS sensors. As you know new sensors must be activated and saved in the car's ECM. When I used the TSGUN TPMS Relearn Tool and rescanned all the sensors, I was able to get the menu instructions to insert the tool into the OBDII port, and I was able to save these sensor settings to the car’s ECM and dashboard warning lights disappeared. Overall, it is easy to bind and use, works well, made with good material and is a cheaper investment for a family garage then everytime visit a workshop. I will upload a video review in 1 or 2 weeks. ... show more

    • Didn't work with my x431v+
The media could not be loaded. Couldn't get the tpms tab to work with my x431v+ even with the latest software. :( Apparently the older launch x431v+ scanners will not support the TPMS software even with the latest updates. My scanner quit just shortly after I wrote my first review so I updated to a newer version. then it worked fine for a few times. Cardiag even got me another activation code after I lost the one they sent with the TSGUN. Now after less than 5 Uses the TSGUN screen went blank ( it beeps and the backlight comes on but I get a white screen). Also doesnt seem to communicate with the scanner. Really frustrated! If I hadn't purchased a bunch of Launch's TPMS sensors I would toss the thing in the trash and write the whole mess off. Really would be nice if Launch would send me another one, but I am about sick of their products. ... show more

Awesome tpms tool. Paired up with my pro3+ scanner, updaded firmware and was ready to go. I replaced 1 rim on my car and it was freaking out becouse the sensor id was not programmed to the car. Programmed no problems. Also great when you do tire rotation, program the sensors in the correct order. Feels durable and solid. Happy with the tpms gun. ... show more
