Actron CP9449 Great unit

This is my second Actron unit. My regular scan tool wouldn't read the brake ECM. What a great item this is. Pinpoints the problem and saves the guesswork. Gives the code and the Code explanation - "open circuit LF Speed Sensor". Sure enough the lead had broken inside the sensor plug from the harness. Also saves the history with back up 9v battery. Shows Current or history. Pays for itself with first repair. It's a wow. USB for firmware upgrade if needed. Nice case.
