4H and 4L switches
Check whether the 4H switch (terminals 4 and 7) and 4L
switch (terminals 12 and 3 ) work as specified in the table
below. If yes, the continuity is established on these
switches. If not, check the switches, shift rails, transfer
case, and rear cover, and replace the failed parts.

Power GND
Check that there is a continuity between the power GND
pin (terminal 7) and transfer case. If not, replace the
grounding wire.
Resistance of electromagnetic coil
Check the resistance between electromagnetic clutch
solenoid (terminal 8) and power GND (terminal 7). If not,
replace the electromagnetic coil.
