Anti-Theft System: Programming: Notes

NOTE: Programming procedures were written specifically for use with Tech II scan tool. Other generic scan tools can be used, but may have limited functions.

If replacing vehicle theft deterrent module, new module will learn keys immediately, however, existing Powertrain Control Module (PCM) must learn new fuel continue password when vehicle 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 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 vehicle 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, ensure to use only a master key (Black) during procedure. If a valet key (Gray) is learned first, vehicle theft deterrent module will not allow additional keys to be learned.
