I have it on good authority, if you type Google into Google, you can break the internet.
Using the 1551 is pretty easy... Start off with Rapid Data Transfer, option 1 as I recall, then the address number as the same as they are listed in . 01 for engine, 08 for HVAC, 56 for radio and so on. Input the 2 digit address and then hit [Q] to scan said address. Then the functions are the same, 08 for Measuring Blocks, 04 for Basic Settings and such...
I learned on the 1551, after I got my number right.. why do I keep getting readiness when I'm trying to scan the airbag?
