Vehicles produced from 6/30/2011 to 9/18/2011
Do not replace any parts.
1. Perform a vehicle test using ISTA and complete all the corresponding test modules related to the anti-theft alarm system.

Note:
Inform the customer that it is only possible to open the tailgate using the remote control after the vehicle has been unlocked.
