Threw one code, code 29. It won't clear it out. And says '(ODM) Output Driver Module Fault. EAS circuitry.

I have no idea what that means. The fans will come on with the SES light. It's a 94 Trans Am, auto. Anyone know what this code means?

Tryed clearing it by unhooking the battery but it keeps coming back.

 

The code is for the Electric Air Pump,which is located under the coil.

Check the wiring and ground strap,it grounds on the coil stud.

It could also be a bad pump,you should be able to get one cheap as most people have deleted theirs.

 

thanks for the reply. turned out it was just a blown fuse for the air pump causing the SES light and fans to come on and drive me crazy. All is well now.

 

Glad too hear it was an easy fix

 

ok, here's the bad news. the fuse blows due to high resistance in the AIR pump. usually there will be water in the pump. typically it wont be long before it blows the fuse again. you should either delete the pump, or replace it. if the fuse blows again, and you want to replace it, give me a buzz. I have a few of them laying around I'll give you one for like $5 or something if you pick it up. maybe it wont blow again. good luck.

Yep, had that happen to me all winter last year. Must've gotten some water in there and it froze. I replaced the fuse probably 15 times last year. But after it warmed up last summer I didn't/haven't had any problems with it.

BTW, the fans are programmed to come on with all SES lights.
