Larry,

If the ETA is bad it just will not work. No such thing as going bad, either it does work or don't work properly. I have heard that ETA can take out other electrical items but only in the case of faulty or crack wires. Issues such as bad wiring harness could cause other electrical components to be harmed. It is possible to have a fuse blown first before you have a major electrical component harmed by the ETA. Most likely if your ETA is bad it is because of the worn gears inside the ETA if you don't have a electrical harness issue.

One way to confirm whether or not your ETA is working is to turn your ignition switch to the #2 position as if you are scanning codes. Then listen for the ETA to make a hi-pitch noise. The hi-pitch noise is the ETA's butterfly setting itself in the correct position to allow the engine to start with proper airflow. Look inside the ETA and see if the butterfly is adjusting itself by opening and closing.

If you don't hear the hi-pitch sound or see the butterfly adjusting itself then you may want to reset/reprogram the ETA. I can't remember at the moment how to reset the ETA but I will get back to you after I look it up. It goes something like turn your ignition switch on and stepping on the accelerator pedal but I will get back to you on that one.

Far as the Base Module, I rarely here of it going bad. Usually a fuse would blow I really doubt if your Base Module is fried. I continue to suggest that you scan each module to see if you get fault codes before buying a new modules.


JimF can really help you out on ETA I suggest contacting him. I had my fair share of dealing with ETA so before you purchase a new one make sure yours is definitely shot.
