If my electrician is correct it seems we need to replace ECU because of the starting issues, also worth to mention I have a jeep grand Cherokee 4.7 year 2000 and we are based in Europe. (car is imported from states years ago)
I am wondering if ’ JEEP GRAND CHEROKEE (WJ) ENGINE CONTROL UNIT/MODULE ECU P56044668AF’ will work with the current car?
What do you suggest, since they’re a lot of different ECU types… and also in Europe is very difficult to find those ECU…
My only concern is to understand what information I have to check on ECU to know if that will work with my jeep? what code or bar code I have to check?
They are the same part, the suffix “AG” supersedes “AF”.
P/N 56044668AG may have an improved part inside or updated software.
If the module you are going to buy is used, it will have the VIN and immobilizer data from the other vehicle recorded inside, if you can’t rewrite this data, the module won’t work.
Then you’re going to have a problem when it comes time for inspection, I would think
Because if you put in an incorrect ecu that allows you to start the engine, but the check engine light remains on at idle . . . a possible implication is the ecu may be looking for sensors that your vehicle does not have, but the donor vehicle did.
And that may be a problem that’s impossible to fix
I think you’d better be 100% sure the ecu is in fact the problem
Seems to me somebody’s just trying to make an educated guess at this point
Many modules get needlessly replaced . . . when in fact the real problem wasn’t identified, due to poor and/or incomplete diagnosis
