This bulletin is being issued to revise the PASS-KEYIII® Relearn
procedure in the Theft Deterrent sub-section of the affected Service Manuals.
Please replace the current information in the Service Manual with the following
information.
The following information has been updated within SI2000 for 1998-2000.
If you are using a paper version of these Service Manuals, please make a reference
to this bulletin on the affected page.
The above mentioned Service Manuals 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.
