Serious Passlock Problems

[Paul Hunter]

It`s impossible to relearn the passlock, the security lamp will not stop flashing, Cylinder lock and ingnition switch are replaced, wiring to BCM ok, voltage from ignition switch changes from 5.0V to 2.8V. the PCM disable the fuel injection every time. I´h tried everything I´h read in this forum with the key in on position for over 30min, but it´s still flashing. Can it be a failure in the BCM?
