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 i-TPMS sensor. The BMW I was diagnosing had two TPMS error codes - one for the right rear wheel sensor, a second for the i-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!
