The 4WD transfer case encoder motor position sensor or the selector switch may fail causing the service 4WD message to be displayed. Fault code(s) stored in the transfer case control module will be of assistance in determining the exact fault causing the message to be displayed.

    4WD Service light came on intermittently. 4WD/2WD indicator lights would indicate Neutral or 4WD-L and the engine would bog down until it shifted out of Low. "System Stability Disabled" warning would also come on. Took to a mechanic that want about $570 to instal the new 4WD Transfer Case Postion Sensor. this really seams to be a manufacturing defect, but it past warranty.

    shifts it self out of 2 wheel drive, lite blinks and will not engage and go into gear. Works later after a few minutes. When in 4 wheel , it will not in engage sometimes and message comes on to service 4 wheel drive. From research it seem that it is the transfer case sensor. It has done one or more of these things in the last 30 days and then run ok

    sometimes when driving my truck will shift into 4wd and when i push the button to put it back into 2wd the light just flashes. i have to restart my truck several times before it will switch back.

    At approx 30000, SER 4WD message, dealer said it was a bad transfer case motor, replaced motor.
    At 65000 same problem same solution.
    At 105000 same problem, now wondering if outside moisture is causing problem. Dried transfer case motor
    out and problem seems to be gone. Recall last times problem occured was raining and damp for prolong time. Another Suburban owner stated he cured problem by sealing around transfer case motor with HD sealer. Might be worth a try.
