ISSUE
The 4X4 indicator lamps may flash on some vehicles. This may be due to oxidation buildup and/or premature wear on the sense plate of the shift motor which can send incorrect signals to the 4X4 controller. Terminals on the transfer case connector may also develop a resistive film, leading to faulty signals to the 4X4 controller.

ACTION
Install a new shift motor and/or speed sensors with new terminal material. Refer to the following Service Procedure for details.
