⚡ At a Glance

  • Best for: DIY motorists and independent garages needing quick TPMS resets

Design suits most GM series, though some special or upgraded models may be incompatible. Durable ABS shell and simple one-button operation make relearning straightforward.


Rapid sensor relearning - with activation in one to two minutes

Activation occurs when the learn button is pressed while the tool sits against the tyre sidewall near the valve stem, with a responsive internal circuit that completes the relearn within 1-2 minutes. Correct antenna position and a fresh 9V battery are required for reliable signalling.

Fast resets let users complete a full sensor relearn during a single tyre service, reducing downtime. That speed is useful when replacing sensors or fitting new tyres during a busy workshop session.

Simple hands-on operation - with a single learn button and clear placement steps

Relearning follows a physical process: ensure the vehicle is in learning mode, hold the tool against the tyre sidewall near the valve stem, then press the learn button, while monitoring the vehicle's maintenance prompts.

Clear, repeatable steps reduce user error and training time for technicians. Even first-time users can complete relearns without specialist equipment or complex menus.

Robust for workshop use - thanks to an ABS shell and wide operating range

A hard ABS plastic shell shields internal electronics from dust and splashing water, while the tool operates across a -20 to 80°C temperature range, and measures about 6.1 x 2.4 x 1.4 inches for comfortable handling.

Durable construction tolerates typical garage conditions and frequent handling. Compact dimensions and water resistance mean easy storage and reliable day-to-day use.
