Let me explain better. Normally, when you plug the scan tool in, a blue light comes on indicating there is power to the tool. Then you connect to bluetooth on your device and you can scan the engine or analyze certatin data parameters that are monitored. When I plug my scan tool in, sometimes the light comes on and sometimes it doesnt. Seems like it loses power or doesnt get power intermittently. Sometimes, even if the light is on, I cannot connect to bluetooth. I checked with the BlueDriver help line and they told me that my OBD2 port is probably bad. Additionally, everytime I check the power on Pin 16 of my OBD port, I consistently read 12(ish) volts. When it does decide to connect to the vehicle, I can do everything as intended. When it doesnt connect, obviously I cannot do anything with the tool. Works about 50% of the time.
Other vehicles that I tested the scan tool in were a 2011 Expedition, a 2017 Mercedes G wagon, and a 2006 Acura. Scan tool worked perfectly in all of these other vehicles without a glitch.
