The Alligator sens.it RS universal TPMS sensors from Wegmann automotive USA Inc. cover the fifth generation Toyota Supra.
The Supra is among Toyota's vehicles with auto-learn TPMS sensors. The car's system should automatically learn TPMS changes (new tires, wheels or sensors) after a few minutes of driving, and tire pressures will update on the control display.
Wegmann provides this guide in the event the settings aren't detected automatically:
From the Toyota Supra Command menu, select My Vehicle, Vehicle Status, Tire Pressure Monitor, Tire Settings. Select the set type (summer/winter), then set it as current. Select the tire type that is mounted on the rear (tire size & rating) and the maximum speed. Finally, select Confirm Settings and drive the vehicle. The process is complete once the tires change from gray to green in the display. The current tire pressures will be set as the baseline psi for the system also.
The Alligator sensor also supports the system's location-specific status of the tires: green shows that the TPMS is functioning normally and all tires have nominal pressures (based on the baseline psi), yellow indicates a flat tire or a major drop in pressure, and grey means that there's a sensor/system malfunction or the display is still storing the changes during the drive after a reset. Certain models can also show the current tire temperatures on the display.
Regardless of the tool a technician uses to program Alligator TPMS sensors, the Toyota Supra should be available for programming after the latest software update is completed.
