Good To Know

Q: Does this device require a wired connection to the vehicle OBDII port? A: No, this tool operates wirelessly by sending a radio frequency signal directly to the sensor located inside the tire.

Q: Why is the indicator light flashing but the sensor is not responding during the relearn process? A: Ensure the 9V battery has a full charge and the antenna is held directly against the tire sidewall near the valve stem.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
