Module Programming: Notes

The Wireless Ignition Node (WIN) controls the Vehicle Theft Security System (VTSS), Remote Keyless Entry (RKE). When a Powertrain Control Module (PCM) is in need of replacement, perform the following steps in order:

NOTE: The PCM and the WIN should never be replaced at the same time. They should be replaced independently of each other.
  1. If applicable, first replace the PCM with the original WIN still connected to the vehicle.
  2. Using a scan tool program the new PCM. (This will ensure the transfer of the Secret Key data from the original WIN into the new PCM).
  3. Replace the WIN, using the scan tool program the new WIN module. This will transfer the Secret Key data from the PCM into the new WIN.
  4. With the scan tool reprogram the key FOBIK to the new WIN.
  5. Ensure all the customer's keys have been programmed to the new module.
    NOTE: If the original keys do not successfully program to the new WIN after the proper procedures are followed correctly, programming new keys will be necessary.
    NOTE: Programming the PCM or WIN is done using a diagnostic scan tool and a PIN to enter secure access mode. If three attempts are made to enter secure access mode using an incorrect PIN, secure access mode will be locked out for one hour. To exit this lockout mode, turn the ignition to the RUN position for one hour and then enter the correct PIN. Be certain that all accessories are turned OFF. Also, monitor the battery state and connect a battery charger if necessary.
    CAUTION: Read all notes and cautions for programming procedures.
    NOTE: Have a unique vehicle PIN readily available before running the routine
    CAUTION: If the PCM and WIN are replaced at the same time, the PCM MUST be programmed before the WIN.
    NOTE: If the PCM and the WIN are replaced at the same time, all vehicle keys will need to be replaced and programmed to the new WIN.
    CAUTION: Read all notes and cautions for programming procedures.
    NOTE: If the original keys do not successfully program to the new WIN after the proper procedures are followed correctly, programming new keys will be necessary.
    NOTE: A maximum of eight keys can be learned by the WIN. Once a key is learned by a WIN, that key has acquired the Secret Key for that WIN and cannot be transferred to any other WIN or vehicle.
    CAUTION: Read all notes and cautions for programming procedures.
    CAUTION: If the PCM and WIN are replaced at the same time, the PCM MUST be programmed before the WIN.
