Remove the kick panel on the passenger side. Contort your body so that you can lay down and look up inside behind the upper wall. You will see it bolted up there behind where there would normally be a glove box. If not then its under the seat? You can use a paper clip to jump the ALDL to pull codes but if your SES light is not coming on there wont be any codes to show.

 

not to sound stupid but what does alda and ses stand for?

 

Assembly Line Diagnostic Link = ALDL
Service Engine Soon = SES

 

ALDL= Assembly Line Diagnostic Link

SES= Service Engine Soon...Check Eng light
