Only sensors can be programmed with the ALLIGATOR programming device PT1. A readout function was deliberately omitted. Thus, the device is the ideal and cost-effective addition to wireless TPMS hand tools. The sensors are programmed quickly and easily using the free software on a PC or notebook with a Windows operating system. The software guides the user intuitively through the programming process and rules out operating errors. Thanks to the online connection, the software is always up to date and new vehicle models are added automatically.
