P1848 SOLENOID DISCONNECT
Description
INFOID:0000000009886130
When power and ground is supplied from the differential lock control unit, the differential lock solenoid will
actuate to move the pressure plate against the cam ring to lock the differential. By reversing polarity at the dif-
ferential lock control unit, the differential lock solenoid moves the pressure plate away from the cam ring to
unlock the differential.
