Wireless Ignition Node Receiver - Module Programming
WIN PROGRAMMING
The Wireless Ignition Node (WIN) controls the Vehicle Theft Security System (VTSS). When a Powertrain Control Module (PCM) for a gasoline engine, or an Engine Control Module (ECM) for a diesel engine, and the Wireless Ignition Node (WIN), are need replacement, perform the following steps in order:
NOTE: The PCM and the WIN should never be replaced at the same time. They should be replace independently of each other.
1. If applicable first replace the PCM/ECM, with the original WIN still connected to the vehicle.
2. Using the appropriate service information program the new PCM/ECM. (This will ensure the Secret Key Transfer from the original WIN into the new PCM/ECM).
3. Now replace and program the WIN. This will retain the Secret Key from the PCM/ECM back into the new WIN.
4. With the scan tool, select Miscellaneous Functions, WCM/Wireless Control Module or WIN. Then select the desired procedure and follow the display on the scan tool.
5. If the vehicle is equipped with Tire Pressure Monitoring System program the Placard Pressure Values into the WIN.
6. Ensure all the customer's keys have been programmed into the new module if necessary.
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 KEY CODE 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/ECM, and each ignition key transponder chip. When the PCM/ECM 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 , ECM REPLACED , WCM/WIN REPLACE , or TIPM REPLACED under MISCELLANEOUS FUNCTIONS for the WIRELESS IGNITION NODE/WIN menu item as appropriate.
NOTE: Programming the PCM/ECM 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 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.
NOTE: Before replacing the ECU for a failed driver, control circuit or ground circuit, be sure to check the related component/circuit integrity for failures not detected due to a double fault in the circuit. Most ECM driver/control circuit failures are caused by internal component failures (i.e. relay and solenoids) and shorted circuits (i.e. pull-ups, drivers and switched circuits). These failures are difficult to detect when a double fault has occurred and only one DTC has set.
ECM/SKIM/WCM PROGRAMMING
When a ECM and the SKIM are replaced at the same time perform the following steps in order:
1. Program the new SKIM
2. Program the new ECM
3. Replace all ignition keys and program them to the new SKIM.
ECM/SKIM/WCM PROGRAMMING
When an ECM (Bosch) and the SKIM are replaced at the same time perform the following steps in order:
1. Program the new SKIM
2. Program the new ECM (Bosch)
3. Replace all ignition keys and program them to the new SKIM.
PROGRAMMING THE SKIM
CAUTION: Read all notes and cautions for programming procedures.
1. Connect a battery charger to the vehicle.
2. Connect the Scantool.
CAUTION: If the ECM/PCM and SKREEM/WCM are replaced at the same time, the ECM/PCM MUST be programmed before the SKREEM/WCM.
3. Select "ECU View".
4. Select "WCM/WIN".
5. Select "Miscellaneous Functions".
6. Select WCM/WIN replaced.
7. Enter the PIN when prompted.
8. Verify the correct information.
NOTE: If the PCM/ECM and the SKIM 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 transponder ID code is learned by the module and the transponder acquires the unique Secret Key ID code from the WIN. To program ignition keys into the WIN, follow the programming steps outlined in the diagnostic scan tool for PROGRAM IGNITION KEYS OR KEY FOBS under MISCELLANEOUS FUNCTIONS for the WIRELESS IGNITION NODE/WIN menu item.
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 to each WIN. Once a key is learned to a WIN, that key has acquired the Secret Key for that WIN and cannot be transferred to any other WIN or vehicle.
If FOBIK programming is unsuccessful, the scan tool will display one of the following error messages:
- PROGRAMMING NOT ATTEMPTED - The scan tool attempts to read the programmed key status and there are no keys programmed into WIN memory.
- PROGRAMMING KEY FAILED (POSSIBLE USED KEY FROM WRONG VEHICLE) - WIN is unable to program an FOBIK transponder due to one of the following:
- The FOBIK transponder is ineffective.
- The ignition FOBIK is or has been already programmed to another vehicle.
- 8 KEYS ALREADY LEARNED, PROGRAMMING NOT DONE - The SKREEM transponder ID memory is full.
- LEARNED KEY IN IGNITION - The ID for the FOBIK that is currently in the WIN cylinder is already programmed into WIN memory.
