Replacing a ecm

There isn't much involved in replacing it. Depending on what kind of motor you have it should just be bolted to the side of the engine with a couple of harnesses going to it. Since you truck is a 2007 it should be under warranty and they should replace it depending on the miles and different things.

 

Definitely worth your time to call your International dealer and check for warranty status on the engine. The engine warranty is different from the truck warranty. Based on what make of engine you have and mileage is, it very well may be under warranty. If you have a good relationship with the dealer and it isn't covered by warranty you still may be able to get some kind of policy or a thing they used to call "Customer good will". That basically is Cummins or Cat will help you out a little and may supply a new ECM but you have to pay for programming and installation. Or give you an ECM at cost or whatever. Better than nothing. When you call the dealer, always have the last 8 digits from your VIN ready to give them so they enter it in their computer system to check your engine warranty status. Good luck.

 

I would troubleshoot the ECM wiring first before buying one. I had one quit working out of the blue to and found that while I was servicing the under carriage I grabbed the frame rail that had the neg cable from the ECM attached and it was so delicate it broke off the bolt. There are also inline fuses that could go bad, these are usually near the battery box on the positive wires going to the ECM. I also had a friend that had his batteries hooked up wrong so the one battery that supplied power to the ECM never recharged via the alternator so the lack of voltage kept it from powering up. You can take the ECM out to the shop and they will test it for 1hr of labor I found on those 1 hr labor charges if its a easy job they sometimes charge 1/2 of the hour labor rate as long as they dont spend much time on it.
