Guys, I've been tuning for quite some time now and when I run into problems I've been pretty good at figuring them out on my own, but this one has me stumped!! This is actually my first post ever on the forum. Here's my issue....I have a V2 that has worked flawlessly for me for years now, up until a few days ago. When I try to read a E38 ECM in V8 I get no communication from the ECM. On the module selection screen (where you can choose between your engine or transmission module) I get a red X that shows "EXT".
My V2 has read many many E38's for quite a while now so I doubt it's a firmware/bootblock issue. Although I did reinstall the firmware and removed/reinstalled my USB drivers just to be sure. I found this issue since my personal vehicle has an E38 ECM and it would not connect to it. It won't connect and read data using V7.5 either. Using the scan tool I get the message "ECM NOT DETECTED". I first began my troubleshooting by trying to connect to three other trucks that were in my shop. 2 of these trucks have E38 ECM's and the other truck had a LS1B ECM. What's stumping me is I can connect and read the LS1B ECM just fine. The other 2 with the E38 I could not. So that makes three E38's my V2 can't detect and read.
Has anyone ever ran I to this situation before? Any help would be greatly appreciated. Thanks in advance!!
