Here is a video in two parts showing how to know and repair a broken steering column where someone (usually a repo company) has forced the steering wheel to turn and broke the lock plate rod. By Stacy
The customer's computer had water intrusion.
This is an easy swap via eeprom, using a used donor ECU.
I changed the eeprom and the 28 legger I am pointing to, as well as the the 14 leg device straight across that forms a triangle with the other 2.
I really do not think swapping the 28 leg device was necessary. Next time I will forgo it and see if I get the same results.
There is a caveat with this board that some of you are probably aware of. I just discovered it today. The components were glued down to hold them in place, before they were soldered. The glue that holds them is pretty firm. You have to liquefy all of your solder before you pry the the device off the board. The glue holds so tight that you can easily lose the device when it let's go. After the first one, I did the rest down inside a drawer in my bench.
You will have to scrape the glue off the devices and off the board in order to get them to lay back down properly for resoldering.
The glue is not solid, it is in spots. It scrapes off easily once you get the spots exposed.
