Using The Transfer Case Shift Control Switch

WARNING: This page is about a different car, the 2011 GMC Yukon XL, 2011 GMC Yukon, 2011 Chevrolet Tahoe, 2011 Chevrolet Suburban, and 2011 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:

The Learn procedure is performed with the ignition in the ACCESSORY position. The shift to transfer case NEUTRAL procedure uses this same procedure, but with the key in the RUN position.

  1. Key OFF for at least 30 seconds.
  2. Engage parking brake.
  3. Place transmission in Neutral.
  4. Turn the transfer case shift control switch (TCSCS) to the 2WD HI position for at least 5 seconds.
  5. Turn the TCSCS clockwise past the 4WD HI position until it stops and hold for at least 30 seconds.
  6. An audible noise from the transfer case encoder motor should occur indicating a successful learn procedure.
