Test Step 1 - WIN Verification

• When entering the PIN, care should be taken because the WIN will only allow 3 consecutive attempts to enter the correct PIN. If 3 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 1 hour. All accessories must be off. A battery charger connected to the battery during this time period is recommended.

• On vehicles equipped with a premium tire pressure monitoring 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/Wireless Ignition Node" 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.

• Reconnect the previously disconnected components and connectors.

• Obtain the vehicle's unique PIN assigned to its original WIN. This number can be obtained from the vehicle invoice.

• First replace the PCM with the original WIN still connected to the vehicle.

• Program the new PCM. This will ensure the secret key transfer from the original WIN into the new PCM.

• Now replace and program the WIN if necessary. This will retain the secret key from the PCM back into the new WIN.

• With the scan tool, select Miscellaneous Functions, WIN/Wireless Ignition Node. Then select the desired procedure and follow the display on the scan tool.

• If the vehicle is equipped with tire pressure monitoring system program the placard pressure values into the WIN/WIN.

• Ensure all the customer's keys have been programmed into the new module if necessary.

• With the scan tool, erase all DTCs. Perform 5 ignition key cycles, leaving the key on for at least 90 seconds per cycle.

• With the scan tool, read WIN DTCs.

• If the PCM and the WIN are replaced at the same time, program the PCM VIN into the PCM first.

• During PCM replacement, use the following steps to ensure transfer of the secret key information from the WIN to the new PCM. The PCM stores this information only. 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.

• If this vehicle is equipped with a steering column lock module, it must be replaced along with the WIN.

Are there any WIN DTCs present?

Yes

• Perform the appropriate diagnostic procedure.

No

• Repair is complete.
