why wont CarMD read anything on the PT cruiser plug?
Tried to check for error codes on 2006 PT cruiser that im buying but nothing registers when I plug in the cable/module for CarMD, similar to what MVA/DMV reads for inspection. When I put it on any other car it say "reading" Then I turn the key to on and after about a minute or less it beeps twice indicating it dont reading. The PT show nothing, dead with the key on off or running. Any ideas? Thanks for your time.
