If only it was still as easy like in the "good old days":
GM - Paperclip across two terminals on the diagnostic port
Ford - Voltmeter across two contacts on the ECU
Honda/Mazda - Same as Ford in some cases and other...just push the button and
count the lights.
Hey Shane,
I checked out the OpenDiag and can't read any of the messages...wazzup wit
dat? ;)
BTW: If you're anywhere near Polk or Embarcadero...DON'T drop your wallet.
Also, O'Farrell street (after 7pm) is "really interesting"...hehehehe.
