WARNING: This page does not describe the selected car, but rather 98 other vehicles, including the 2001 Saturn SW2, 2001 Saturn SL2, 2001 Saturn SL1, 2001 Saturn SL, and 2001 Saturn SC2. However, it is still accessible from the selected car via links, so may be relevant.
- If replacing a theft deterrent module, the new module will learn keys immediately. However, the existing Powertrain Control Module (PCM) must learn the new fuel continue password when theft deterrent module is replaced.
- If replacing a PCM, 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.
- When performing 30 minute relearn procedure, all previously learned keys will be erased from theft deterrent module's memory
- Additional keys may be learned immediately after 30 minute relearn procedure by inserting additional key to be learned and turning ignition switch to RUN position within 10 seconds of removing previously learned key.
- When performing 30 minute relearn procedure, be sure to use only a master key (Black) during procedure. If a valet key (Gray) is learned first, theft deterrent module will not allow additional keys to be learned.
