We have a Customer's Cadillac here that we diagnosed with a faulty ECM. I wanted to By-Pass the dealer and get an ECM from another source other than GM. I found Automotive Electronic Solutions on the internet and gave them a call explaining that I needed an ECM diagnosed and if it is indeed bad, replaced and programmed. I was assured by the "Partsoligist" (Is that even a real word?) that they have the ability to load a remanufactured ECM with the factory Cadillac software no problem.
I Recieved a call from AES telling me that the ECM was bad, they are going to send out a replacement already programmed and ready to go, Just have to plug it in and go. I recieved the ECM, plugged it in, Engine will not crank. The ECM that I recieved does not have the proper coding for the Cadillac alarm system. I had the car towed to a GM dealer for alarm programming for $108.00, engine did start but now we have a "Check engine" light on. Car never had a check engine lamp prior to ECM failure. The code we were getting is a code for the MAF sensor not detecting proper voltage. We probed the wires to the MAF, we have good voltage from MAF to the ECM input connector, no voltage reference on the output connector, Scanner reads zero volts for MAF.
I called their "Tech support hotline" and they logged my call. That was 7 days ago, I called back the same day and a rather rude guy basically told me that they will get back to me when they want to. I then had the sinking feeling that I just got screwed. Not to mention that my customer has been out of a car for a month now. I have now ordered a genuine ECM from GM and will once again have the dealer program it. These guys will not return your calls, will not help you after the sale at all. These guys sounded too good to be true (preprogrammed ECM and just plug it in!) Just another BS company that takes your dollars and then forgets all about you the customer. I lost my a* on this job and now I have an unhappy customer because of this company and I'll never use them again.
