Good morning,
There is a chip in the ECM that is called the prom. It stands for programmable read-only memory.
When this code happens, the chip has to be replaced.
You need to remove the ECM, open the plate with the 2 small bolts, and give me the number off the prom. That way I can try and see if it is still available.
I attached the procedure and some pictures for you of the removal.
