How do I use it?
Find your car's OBD port, turn on the ignition and plug the MS309 in. Press enter on the tool and the unit will then scan for the protocol that your car uses, the unit will then link into your car and display the engine fault codes it has found. You then select the 'Erase' option from the menu and then the engine warning light will go off when you restart the car.Of course you will need to fix the fault to avoid the engine waring light appearing again
