BACKGROUND
On affected vehicles that are not driven for 2 weeks or more, a parasitic current draw from the moonroof control unit can discharge the 12 V battery. In addition, the moonroof may reverse itself while closing. To correct this problem, the moonroof control unit software needs to be updated. The tool used to update the moonroof control unit software is called the Flash Pack.
All owners of affected vehicles will be sent a notification of this product update.

REPAIR PROCEDURE
1. Using a trim tool, remove the map light lenses from the roof console.
2. Remove the four screws from the roof console, then remove the console from the roof. You don't need to disconnect the wire harness connectors; just let the console hang.
3. Start the engine.
NOTICE
To avoid damaging the Flash Pack, do not connect it to the vehicle until the engine is started. And never crank the engine when the Flash Pack is connected to the vehicle.
4. Connect the Flash Pack power connector to the vehicle's 12 V power outlet. The blue POWER indicator on the Flash Pack comes on.
5. Disconnect the moonroof control unit lop connector, then connect the Flash Pack lop connector to the control unit.
6. Press the PROGRAM button on the Flash Pack. The yellow IN PROCESS indicator stays on for about 2 minutes, then the green PASS indicator comes on to let you know the software update is completed.
NOTICE
To avoid damaging the Flash Pack, do not disconnect it or operate anything electrical (audio unit, headlights, windows, door locks, etc.) when the IN PROCESS indicator is on.
NOTE:
If the red FAIL indicator comes on during the update, press the PROGRAM button again. If the FAIL indicator comes on again, the moonroof control unit (motor) needs to be replaced.
7. With the engine still running, disconnect the Flash Pack power connector from the 12 V power outlet, then disconnect the Flash Pack 10P connector from the moonroof control unit, in that order.
8. Turn off the engine.
9. Reconnect the moonroof control unit 10P connector.
10. Reinstall the roof console in the reverse order of removal.
11. Close all the doors and the tailgate.
12. Turn the ignition switch to LOCK (0).
13. Press and hold the center of the moonroof switch (tilt), and turn the ignition switch to ON (II).
14. Release the moonroof switch, and turn the ignition switch to LOCK (0).
15. Repeat steps 13 and 14 four more times.
16. Turn the ignition switch to ON (II).
17. Push and hold the moonroof switch forward (closed) until the moonroof moves to the hard stop (full tilt open) position and backs up slightly. Within 5 seconds, release the moonroof switch, then push and hold it in the forward (closed) position again.
18. Continue holding the moonroof switch forward (closed) until the moonroof moves to the full slide open position and then back to the full closed position.
NOTE:
Be sure to hold the moonroof switch in the forward (closed) position throughout the moonroof's travel. If you release the switch too soon, you'll need to repeat steps 13 thru 18.
19. Make sure the moonroof one-touch feature works in the Open, Close, and Tilt positions.
