  2. Engage parking brake.
  3. Place transmission in Neutral.
  4. Turn the S77 Transfer Case Shift Control Switch to the 2WD High position for at least 5 s. The 2WD High indicator may not illuminate.
  5. Turn the S77 Transfer Case Shift Control Switch clockwise past the 4WD Low position to the neutral request position and hold for at least 30 s.
  6. An audible noise from the A16 Transfer Case Motor should occur, indicating a successful learn procedure.
