Well, I got the P0601 code (internal memory fault) on my 100k mi. 2002 GC 3.3L. It runs fine, but I need to take a 600 mile trip at the end of the month, and would like to know if there's a rebuilt PCM that people on the board have had good results with. There's a lot of rebuilders out there, and of course, they all tout they're best but I need a reliable unit. (don't we all?)
Suggestions?
I think most PCM's are replaced for no reason, however, your's might actually be bad. Most 'rebuilt' units are probably just bench checked and given the 'rebuilt' label. Your best bet might be from a junkyard.
I did a post on this before.
The list of reputable places is short.
On my list, a few have been in business for many years.
Also, make sure they are dedicated to electronic stuff.
Some places do other stuff as well.
