After I Buy Actron CP9575 AutoScannerWhat a great product . Pulls codes quickly with a modest description of code. In addition, it shows various sensor data(rpm, voltage, positions, temps, loads, etc...)and other various on board data that would normally require you to go to a professional shop for. I bought this actron since I was having a problem with my rear O2 sensor in one of my vehicles, which was consistently pulling 2 codes for that sensor. Initially i was resetting it hoping it was a glitch, since i wasn't in any mood to buy a rear O2 & lift the car to replace it. Well luckily with the scanner, i observed that the voltages were stagnant under all conditions. Now this was strange since the voltages dictate the exhaust temperature. The front O2 was showing varying voltages under different loads. well, to make a long story short it turns out that the sensor wiring was frayed requiring an easy splice.
The advantage of knowing on board sensor data is far better than just pulling codes... My recommendation, if you don't mind getting you hands dirty, spend a few extra bucks and get a model that can pull live sensor data like this model. Plus, it's a great show and tell for all you car buddies.
As for updating data via PC, i have yet try that.
