I managed to verify that the ECU on my '95 Cirrus (2.5L V6) was bad. I found a guaranteed salvage part for $145 since the dealer wanted $700 for just the ECU.
Once installed all of the codes and run problems of the car disappeared and I was happy. Then after I closed up the car and went in to clean up my wife went out to get something and when she touched the door the car starting honking like crazy. I removed the battery connection and it stopped; it did the same thing again when reconnected.
I didn't have an alarm system before. Have I left something out of the sequence in the replacement of the ECU? like programming? If so, can I manage it somehow or do I need to get someone to do something? Who can normally do this for me or what kind of tool will I need to do it myself?
Regards.
