[2002] Bad BCM?

[Dcopp92]

Hello.

a '02 Q45 i recently purchased has issues where the FOB does not lock/unlock the doors or open the trunk. Power lock button on driver-side door does not work either.

Power seat positioning does not work either, and i thought that to be managed by the BCM because of the driver "preference memory" that you can set.

When i had it scanned at O'reilly's, their OBD scanner returned a code along the lines of an "immu-key"? but my FOB does start the car from the ignition.

Could these symptons be from a bad BCM?

Unfortunately, I don't have much experience with that series of Q. If you haven't checked out your car's factory service manual, it's available at www.infinitiservicemanual.com - there may be some "without consult" tests that you can perform on your own.
