Perform the following steps in order to verify your remote activation customization:

    Important: If the ignition switch is turned OFF or the driver door is opened while the body control module (BCM) is in the customization process, the process will be terminated and the BCM will remain in the most recent mode.

  1. Remove the BCM PRGRM fuse from the fuse panel. Refer to Fuse Block in Wiring Systems.
  2. Close all of the doors.
  3. Close the liftgate.
  4. Turn the ignition to ACC.
  5. The seat belt telltale will flash and the chime will sound 1--4 times in order to indicate that the body control module (BCM) is in the feature customization mode.

  6. Press the transmitter LOCK button.
  7. The seat belt telltale will flash and the chime will sound 1--2 times in order to indicate which remote unlock control mode the BCM is in.

    Each time the transmitter LOCK button is pressed, the mode number will advance. A transition past mode 4 will start over again at mode 1.

  8. Turn the ignition OFF.
  9. If you wish to customize other features, customize the features before reinstalling the BCM PRGRM fuse block.
  10. Replace the BCM PRGRM fuse back into the fuse panel. Refer to Fuse Block in Electrical Diagnosis.
  11. Your current customization is now saved.
