Why my current TPMS Tool cannot trigger / activate / reset some sensors ?
That is because your TPMS Triggerring tool is not compatible with that sensor. In other word, it does not carry the TPMS protocole required to communicate with that specific sensor. TPMS sensors on the market are manufactured by different companies. Those companies did not meet to agree on one TPMS wireless protocole. As a result, there are lots of different TPMS sensor protocoles and this number keeps growing as new sensors are coming to the market every day. So if you purchased a TPMS tool a while ago, you will soon start seeing vehicles from which you cannot trigger the TPMS sensors unless your TPMS Tool can be upgraded over the internet with new TPMS sensors protocoles. This is why you should make sure that your TPMS Tool can be upgradable easilly through the internet, or else become obsolete quickly.
