A GM SPO replacement PCM is in a functional state to learn the fuel enable password from the BCM. If the BCM is replaced, the PCM must be placed in the password learning mode to relearn the new fuel enable password from the BCM. The loss of PCM battery or ignition voltage does not affect the programmed password information. Refer to Programming Theft Deterrent System Components .
