Under your steering column and just to the right you will find the ALDL...basically just a wiring harness female end....it may have a small cover on it...if so remove and with the ignition key in the OFF position, take a paper clip and insert one end into the upper right contact and the other into the contact just to the left.....turn your ignition to the ON position, but dont start the car......your check engine light will flash once (signaling the number 1) then a pause, then flash twice (signaling the number 2)...it will do this 3 times.....and then flash your error codes.....hope this helps :)
