Question
Why do some TPMS tools include a “sensor activation wand”?
Answer
To wake sensors individually (e.g., during tire rotation) without waking all four.
Explain
The wand lets technicians target one sensor at a time, simplifying ID-to-position mapping. CHEPQ wands have a 10cm range for precision.
