When a tire pressure light comes on after a tire swap or rotation, an Autel TPMS tool lets you trigger the sensors, read their IDs, and run the relearn right at the wheel. The TS408 covers the basics, while the TS508, ITS600, and TS900 add more service functions and programming. Pair them with Autel MX-Sensors, programmable 315 and 433 MHz sensors that can replace a long list of OE sensors, so you’re not stocking a different part for every make.
