AV-SCANNER / Accessory guides / Tyres, brakes and cooling
This guide covers the complete use of a Tire Pressure Monitoring System (TPMS) activation tool, from choosing the right type for your fleet or shop through to interpreting sensor IDs and confirming a repair. It is written for working mechanics and serious DIYers who already understand basic electrical testing and want a repeatable, safe procedure for waking sensors and reading their identifiers. After working through the sections you will be able to select a compatible tool, connect it without damaging vehicle electronics, trigger and read sensors on most common systems, and decide when a fault is beyond an activation tool's scope.
Guidance is general and covers many makes. Exact procedures and values vary by model, so confirm them in the factory service information for your vehicle.
