Wireless Ignition Node (WIN) Verification Test

WIRELESS IGNITION NODE (WIN) VERIFICATION

For a complete wiring diagram, refer to the Wiring Information.

Perform the following after completion of a diagnostic repair:

NOTE: When entering the Personal Identification Number (PIN), care should be taken because the WIN will only allow three consecutive attempts to enter the correct PIN. If three consecutive incorrect PIN's are entered the WIN will Lock Out the scan tool. To exit Lock Mode, the ignition key must remain in the Run position for one hour. All accessories must be off. A battery charger connected to the battery during this time period is recommended.

NOTE: On vehicles equipped with a Base Tire Pressure Monitoring (TPM) system, when the WIN and/or the spare tire pressure sensor is replaced with a new unit, a diagnostic scan tool MUST be used to run a routine that allows the WIN to be programmed with the ID number and location of the spare tire pressure sensor mounted in the wheel of the spare tire. Follow the programming steps outlined in the diagnostic scan tool for "Learn Spare Tire Sensor ID" under "Miscellaneous Functions" for the "WIN" menu item as appropriate. In addition, if the WIN is replaced, the spare tire must be dismounted from its wheel to access and note the ID number on the spare tire pressure sensor so that the ID code for that sensor can be programmed into the new WIN.

1. Reconnect the previously disconnected components and connectors.
2. Obtain the vehicle's unique Personal Identification Number (PIN) assigned to it's original WIN. This number can be obtained from the original vehicle invoice or from your Service Manager or Parts Manager.

NOTE: If the Powertrain Control Module (PCM) and the WIN are replaced at the same time, program the PCM VIN into the PCM first.

NOTE: The PCM stores the secret key information. If the WIN ever needs to be replaced, the secret key information can be retrieved from the PCM and then transferred to the WIN for security use.

During PCM/ECM replacement, use the following steps to verify the transfer of the secret key information from the WIN to the new PCM:

1. If the PCM is to be replaced, first, replace the PCM/ECM with the original WIN still connected to the vehicle. If the PCM is not being replaced, go to step 3.
2. Using the appropriate Service Information to program the new PCM/ECM. (This will verify the Secret Key Transfer from the original WIN into the new PCM/ECM).
3. Now replace and program (WIN Replaced) the WIN (if necessary). This will cause the WIN to receive the Secret Key from the PCM/ECM back into the new WIN.

NOTE: If this vehicle is equipped with a Steering Column Lock Module, it must be replaced along with the WIN. Whenever a WIN is replaced the Steering Wheel Lock Module MUST be replaced.

4. Using the scan tool, select Miscellaneous Functions, WIN. Then select the desired procedure and follow the display on the scan tool.
5. If the vehicle is equipped with the Base Tire Pressure Monitoring System, program the Placard Pressure Values into the WIN.
6. Make sure all the customer's keys have been programmed into the new module if necessary.
7. Using the scan tool, erase all DTCs. Perform five ignition key cycles, leaving the key on for at least 90 seconds per cycle.
8. Using the scan tool, read WIN DTCs.

Are there any WIN DTCs present?

Yes

- Repair not complete, go to and perform the appropriate diagnostic procedure.

No

- Repair is complete.
