Re: Why can't I scan the car while it's running? (Mawrick)
Check all ground connections in car. Especially the main ground for all the motronic components on front of engine, behind alternator.
Whether ABS is diagnostics capable depends whether your car has Teves-02 or Teves-04. Teves-02 can only do blink codes. Teves-04 is capable.
