In this video, ATEQ shares that direct TPMS systems use TPMS sensors inside the wheel to report pressure data to the vehicle’s ECU in real-time. The direct systems include Asian, domestic and European vehicles. An indirect TPMS system uses an ABS system to monitor the speed of the wheel in order to record tire pressure readings correctly. Indirect systems include Asian and some European vehicles. The VT15, VT31, VT36, and VT56 can read 100 percent of direct TPMS sensor information.
