|There is a white storage bin on the shelf in the tool crib labeled "Automotive Tools". The code reader should be in there inside its black nylon case along with the cables.
Usually, when the "Check Engine" light comes on in my car I fix it by covering it with a piece of electrical tape. But if the tape keeps falling off, you can use the code reader to determine what your car is complaining about.
Should remain at i3 unless you get specific permission from the owner.
Change the battery once in a while.
