Alligator sens.it RS universal TPMS sensors now supports auto-learning on the 2019 Chevy Volt and 2021 Chevy Colorado.
These vehicles are among the first GM mid-sized models to have both an auto-relearn feature for the TPMS, and also a fill-assist feature, the initial ones being the new Chevy Corvette C8 and full-size SUVs (Tahoe, Suburban, etc).
Auto Learn allows the vehicle to automatically locate TPMS sensor locations after a tire rotation has been completed or after installing new sensors. Also offered is a Tire Fill Alert System that indicates via audial & visual cues when a tire is being inflated and when it’s been filled to the recommended psi.
When filling a tire, the turn signal will flash on the corner that is being filled and the driver will be informed that the optimal tire pressure has been reached during inflation by sounding a single horn chirp. If the tire is over inflated, the vehicle will sound multiple horn chirps.
