I have a MAC Tools TaskMaster scanner (updated to 2011). While trying to use on my 2002 Accord it will not communicate at all, cant use Global OBD, Transmission, Airbag, Vehicle Specific OBD, nada... However if I use my Actron (autozone) Scanner it will work fine (no trans, airbag etc...) Also my buddy's Snap-on Solus and Modis Work fine as well. I can however use the MAC on my Expediton, Ram, Focus etc..... just does not seem to want to work on the Honda. It just says to Turn Key On, then trys and says no communication. Wondering if I need to Jump a Pin or something... Anyone have any idea's? Right now there are no issues with the car, I just want to make sure my scanner works with all my vehicles, otherwise I am stuck buying a Snap-on Modis.

 

Best thing to do is try it on another Accord.
