All Wheel Drive

Transfer case (Electronic Shift Controls)

The Electronic Shift Control System is powered by the 15A Fuse 17 of the Interior Fuse Panel and a 20A Fuse 9 of the Power Distribution Box.

When an Electronic Shift Control Switch in the Instrument Panel is depressed, the Electronic Shift Control Module will analyze information from the transfer case Shift Position Sensor to verify its current position.

It will also analyze input information from the Speed Sensor and the Clutch Interlock Switch (or Neutral Safety Switch depending upon transmission application). If all design conditions of the system are met, the Electronic Shift Control Module will command the Electric Shift Motor to execute the desired function. After the shift takes place and the motor is turned off, the Electronic Shift Control Module will again look at the inputs from the Shift Position Sensor to determine if the transfer case is in the position that the operator selected. Finally, the Electronic Shift Control Module will illuminate the shift indicator bar lamps located below the Instrument Cluster to indicate that the desired function has been completed.
