2001 Cadillac Seville STSFACTORY OEM SERVICE PROCEDURE

Programming Theft Deterrent System Components

If replacing a Powertrain Control Module (PCM) with a replacement part, after programming, these modules will learn incoming fuel continue password immediately upon receipt of a password message. Once a password message is received and a password is learned, a learn procedure must be performed to change this password again. A PCM which has been previously installed in another vehicle will have learned the other vehicle's fuel continue password and will require a learn procedure after programming to learn current vehicle's password.

  1. Turn ignition on. Attempt to start engine, then release key to ON position (vehicle will not start). Observe SECURITY indicator. After about 10 minutes, SECURITY indicator will turn off. Turn ignition off and wait 5 seconds.
  2. Repeat step Β 1 2 more times for a total of 3 cycles in 30 minutes. Vehicle is now ready to relearn key transponder information and/or passwords on next ignition switch transition from OFF to CRANK position.
  3. NOTE: Vehicle learns key transponder information and/or password on next ignition switch transition from OFF to CRANK position. Ignition switch must be turned to OFF position before attempting to start vehicle.
  4. Start engine. Vehicle has now learned the key transponder information and the PCM has now learned the fuel continue password. Using scan tool, clear any DTCs if needed.
