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?

 

I dont remember off hand that code. but output drivers are usually in the pcm. I'll try to remember to look it up when I get to work monday.

 

According to my haynes manual the obd1 code 29 is "Secondary Air injection"

Says to check AIR system for an open circuit in the wiring. Hope that helps.

 

29 Secondary Air Injection (AIR) pump circuit

Check the AIR pump fuse under the hood.

 

thank you soooo much guys. especially shoebox.

blown fuse for the airpump, replaced it and all is well. The fans and that light on all the time was driving me crazy. I am so glad it is taken care of now.

 

Don't be surprised if it happens again. It is a common occurrence.
