❓How to enter TPMS learning mode？ This tool requires a 9V battery (not included) for operation. To enter TPMS learning mode, please refer to your vehicle’s owner’s manual for model-specific steps, or consult the User Guide (PDF) available under the “Safety and product resources” section of this listing. ❗️❗️Important Note Before use, please first check whether the tire pressure sensors have sufficient battery power and can function properly. This is the most common cause of relearning failures.❗️❗️ If one or several tire sensors cannot be activated after multiple attempts (the issue is caused by low battery or damaged sensors rather than a faulty tool), please replace them with new pre-programmed sensors and try again.
