ISSUE:
A shudder or binding sensation in tight turns while in 4X4 Auto Mode may be experienced on some vehicles. The shudder is due to a high torque output
from the clutch in some transfer cases.
ACTION:
Recalibrate the existing Generic Electronic Module (GEM) if the GEM is identified with engineering part number F77B-14B205-BB. The revised
calibration commands a lower torque which allows the transfer case clutch to engage smoother so shudder or binding should not result. Refer to the
following Service Procedure for details.
SERVICE PROCEDURE
Using Service Bay Diagnostic System (SBDS) machine, use the latest software release to recalibrate the GEM to command a lower minimum torque
level from the transfer case. Follow the instructions below:
1.
Select "Body, Chassis, Electrical" from the SBDS Main Menu.
2.
Enter the Vehicle Identification Number (VIN) of the vehicle being serviced and continue to the "Body, Chassis, Electrical" menu.
3.
Select "Module Reprogramming" under the "Category" scroll box, and "Module Reprogramming" under the "Tool" scroll box.
4.
Follow all on-screen instructions, continue to "Module Reprogramming Procedure" screen and select "GEM Module, Shudder in 4X4 Auto Fix,
4X4 Auto Fix."
5.
Again, continue and follow all on-screen instructions until the GEM module has been reprogrammed.
6.
A copy of the log can now be printed to document what has been done to the vehicle.
If the new calibration does not satisfactorily resolve the concern, refer to TSB 97-3-14 for additional corrective actions.
