This is how you can retrieve your KOEO codes
open your hood, and look at the firewall/drivers fender for this
Pull the plugs from the cap
put your test light into the small plug, and onto a good ground
Sit in the seat, and put your key in the ignition.
Be sure to turn off all accessories
Turn key on
Watch check engine light
Codes on obd 1 are in 2's obd2 are in 3's
It will flash. first will be flash,,,,,,,, flash. that will be 11 ( 3obd2 will be 111)
That code is system pass,
then you will start getting the codes.
All codes are repeated twice
We are working on posting a place where all the codes will be on site available to be able to be looked up.
