2003 Cadillac DeVille
Stupid question - how do I extract the error codes out of my 94 DeVille?
Yep, it works on a 1990. I e-mailed the owner of that site while at work today and after he confirmed it, I tried it on my car tonight. I can finally see what that service engine soon light was whining about(the next time it comes on). My battery died two nights ago due to interior lights being left on, so I won't get to see the code until it happens again. Thanks for your help guys.Stoneage_Caddy said:possibly , i havent tried it on a 90 deville yet , the codes may be diffrent from whats on the page if you can retrive them
anyone else have any ideas here?
Yep, I love the forums. Now I just wish I could find the entire Technical Service Bulletin for the error code I'm getting. I am getting the E49 code, which means:Stoneage_Caddy said:thats great news dude

Stoneage_Caddy said:did a quick search on your code , try this :
its pretty vauge too , im not familiar with the air managment system on cadillacs yet so i cant say much here , maybe check for a vaccum leak ???i suppose there is a solenid for it also , does it idle ok ?
ever try pulling the headlamp switch out of the car and seeing if the park lights stay on ? itd be nice to have wireing diagrams for them too , there might be a parking light relay thats bad , a quick way to tell if it has one would be to call the dealer and ask for a parkling light realy , if they say they there isnt such thing on that car then we'd know
id search the junkyards for the head lamp switch (and relay if it has one)and twilight sentinel stuff , might be able to get them fairly cheap from there
