  • I have a 1999 buick lesabre with a 3800 v6 engine. I connected my 3140g innova scan tool to read live data, but it could not do it. Is there a problem with my tool, or am I doing something wrong. I know I pressed the LD button with no luck. According to innova it will read live data on GM models.
