Electronic Shift Control Module

This module controls operation of transfer case, using inputs from 2WD/4WD selector, vehicle speed sensor, shift position sensor and transmission range sensor or clutch switch. Electronic shift control module is located in right kick panel. Module is equipped with a self-test capability.

If all conditions are correct, electronic control module will signal electric shift motor to shift gear positions. After shift takes place, module will read input from shift position sensor to determine if transfer case is in desired position. Control module will then illuminate push button and dash indicator light.
