Question
Why do some sensors only transmit after driving?
Answer
They stay in “shipping sleep mode” until vibration/centrifugal force wakes them.
Explain
To save battery, sensors don’t transmit when stationary. CHEPQ activation tools use LF signals to wake them without driving, speeding up workshop diagnostics.
