WARNING: This page is about a different car, the 2002 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Do not use this procedure on vehicles equipped with Vehicle Immobilizer option or Canadian Mandatory Base Equipment export option.

NOTE: Use this procedure after replacing Passkey® III ignition keys, theft deterrent control module, or Powertrain Control Module (PCM).

Using Black master Passkey® III ignition key, turn ignition switch to RUN position.
Observe SECURITY indicator. After 10 minutes, SECURITY indicator should turn off.
Turn ignition switch to OFF position, and wait 5 seconds.
Repeat steps 1- 3 two more times for a total of three cycles, or 30 minutes.

NOTE: Vehicle learns key transponder information and/or passwords when ignition switch is cycled from OFF to START. Ignition switch must be turned to OFF position before attempting to start vehicle.

Using Black master Passkey® III ignition key, start vehicle. Vehicle has now learned key transponder information, and PCM has learned fuel continue password.
Using scan tool, clear all DTCs.
