    Did not work on my Nissan Leaf

    This particular scanner ended up not being compatible with my Nissan Leaf using the LeafSpy Lite or Pro app. Kept getting error message. I should have done more research on which scanner is compatible.

    Did not work with my Nissan Leaf with the Leaf Spy App. Need a V1.4 or V1.4 Scanner. Great for other OBD2 vehicles that are compatible but not for Nissan Leaf owners!
