Module Programming






MODULE PROGRAMMING

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.

PROGRAMMING THE SECRET KEY TO THE WIN

The secret key is an ID code that is unique to each WIN. This code is programmed and stored in the WIN, the PCM, and each ignition key transponder chip. When the PCM or WIN is replaced, it is necessary to program the Secret Key Code into the new module using a diagnostic scan tool. Follow the programming steps outlined in the diagnostic scan tool for PCM REPLACED, WIN REPLACED, or TIPM REPLACED under MISCELLANEOUS FUNCTIONS for the WIRELESS CONTROL MODULE menu item as appropriate.

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.

PCM/WIN PROGRAMMING

When an PCM and the WIN are replaced at the same time, perform the following steps in order:

1. Program the new WIN.
2. Replace all ignition keys and program them to the new WIN.

PROGRAMMING THE WIN

CAUTION: Read all notes and cautions for programming procedures.

1. Connect a battery charger to the vehicle.
2. Connect the scan tool.

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.

3. Select "ECU View."
4. Select "WIN".
5. Select "Miscellaneous Functions."
6. Select "WIN Replaced".
7. Enter the PIN when prompted.
8. Cycle ignition key after the successful routine completion.

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.

PROGRAMMING IGNITION KEYS TO THE WIN

Each FOBIK has a unique ID code that is assigned at the time the key is manufactured. When a key is programmed into the WIN, the module learns the transponder ID code and the transponder acquires the unique Secret Key ID code from the WIN.

CAUTION: Read all notes and cautions for programming procedures.

1. Connect a battery charger to the vehicle.
2. Connect the scan tool.
3. Have a unique vehicle PIN readily available before running the routine.
4. Ignition key should be in RUN position.
5. Select "ECU View".
6. Select "WIN Wireless Control".
7. Select "Miscellaneous Functions."
8. Select "Program Ignition Keys or Key FOBs", Start
9. Enter the PIN when prompted.
10. Verify the correct information.
11. Cycle ignition key after the successful routine completion.

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.

PROGRAMMING THE PCM

CAUTION: Read all notes and cautions for programming procedures.

1. Connect a battery charger to the vehicle.
2. Connect the scan tool.
3. Have a unique vehicle PIN readily available before running the routine.
4. Ignition key should be in RUN position.

CAUTION: If the PCM and WIN are replaced at the same time, the PCM MUST be programmed before the WIN.

5. Select "ECU View".
6. Select "WIN Wireless Control".
7. Select "Miscellaneous Functions."
8. Select "PCM Replaced".
9. Enter the PIN when prompted.
10. Verify the correct information.
11. Cycle ignition key after the successful routine completion.
