I have been using an Actron CP9145 scanner for several years on my own vehicles. None of these has been newer than 2001. Yesterday, I tried to read a 2005 Tacoma and could not establish communication. I then tried it on my new car (2007 Mazda6) and could not establish communication with that car, either. Does anyone know why this is? Have the communication protocols changed in recent years? Is my scanner obsolete or are we dealing with user error? Thanks. RNR
