Default Re: Rear E-Locker
The e-locker is controlled by the transfer case shift control module. This module monitors both the control and return voltages from the e-locker actuator and if they are incorrect DTC-C0388 is set and SERVICE 4WD is displayed. The control module also has a free wheeling diode to accomodate the e-locker's actuator coil's inductance. The e-locker's coil normal resistance is between 2.2 and 4.3 ohms.
