Makes sense..
..anyway, I would mention that others are suspect of the speed sig from the dash b/c they will know where the test connector in the harness is for that.. then they can take an omh meter reading for verification..
You may also want to clear codes before going in so they can not claim you missed one .
Use the tool for pins 8 and 14 . You will know for sure that you have cleared b/c those both will come back with a single flash , indicating all codes have been cleared
The DM module [ CEL activator with built-in led/sw ] will not show a 1 code as it has to go through all drive cycle self -test before that can happen.
I have much more faith in Indies than I do in dealers...just for the guy to tell you an 02 sensor was going to rectify a No Speed signal code is nutz..
if I ever did that on this group, the lurkers would be on me like flies on s..t
