I've got someone that has a 2005 Tacoma that was getting a P0606 code ("PCM / ECM Processor Fault"), and their dealer confirmed a bad ECU.  If they buy a used ECU with the matching part number from LKQ or someone else, does the ECU have to be flashed before it will work?  Or, does it just need to be reflashed once it's installed?  He knows that the VIN in the ECU has to match the vehicle, to pass his smog check in Mass.

Pretty much all modules now are like this. To cut down on theft, car chopping, etc.

It's all pretty pathetic, if you ask me. We in the fleet department order up multiple vehicles, optioned out identical. So in theory, EVERY module should be the same, have the same part number, etc. For that particular vehicle line. Can I take out an ABS or body controller module, and just plug and play it in another ride? NOPE. I have to have it VIN encoded / decoded, to the current, good unit.

 

Makes it a real hassle. Especially when I am trying to swap it out of a wreck, that got the wiring harness mangled. Little hard to power it up, and grab the data out of it, to make it play nice with the good vehicle. Nice when the theft system goes nuts, and shuts everything down. I used to think just getting the vehicle inside was a problem.................

Normally that code is caused by the computer being confused by a bad downstream O2. Not always, but usually. Guess you'll find out.
