PASS-KEY III - Revised Relearn Procedure

This article has been updated with bulletin No. 02-08-56-001

REVISED RELEARN PROCEDURE
The Service Manual stated either in the title and/or in the text of the Relearn or Autolearn procedure that when replacing an ignition lock cylinder assembly, it is necessary to do the relearn procedure. When replacing an ignition lock cylinder on these vehicles, a relearn procedure is not required.

A programming procedure is still required when replacing a Theft Deterrent Control Module or a steering column assembly that comes with a new Theft Deterrent Control Module and the ignition keys.

IMPORTANT: A new GMSPO service replacement PCM will learn the theft password when the ignition is cycled on for the first time.
