Automatic Transmission
Page 733 of 1333
ignition switch is turned on again until vehicle begins to move, even
if free-wheeling hubs are in locked condition. Light comes on or goes
out by detecting vehicle speed (approximately 3 mph). When vehicle
speed is less than 3 mph, the condition of the automatic free-wheeling
hubs may not agree with the indicator until vehicle speed is
increased. If vehicle has been parked in extremely cold weather in 4WD
mode, the light may remain lit, even after switching to 2WD,
indicating that hubs are still locked.

DESCRIPTION
Transfer case is a part-time, 2-speed unit with a 3-piece
aluminum case. Transfer case has a floor-mounted shifter and integral
speedometer gear. In Montero a Viscous Coupling Unit (VCU) and center
differential allows 2WD-to-4WD shifting at speeds under 62 MPH and
full-time 4WD operation.
WARNING: When battery is disconnected, vehicles equipped with
computers may lose memory data. When battery power is
restored, driveability problems may exist on some vehicles.
These vehicles may require a relearn procedure. See the
COMPUTER RELEARN PROCEDURES article in the GENERAL
INFORMATION section.
TESTING
4WD INDICATOR CONTROL UNIT (MONTERO)
The 4WD indicator control unit is located behind radio or CD
player. Remove 4WD indicator control unit and disconnect harness.
Backprobe harness connector and measure voltage between terminal No. 8
(ground) and each respective terminal. Compare test results with
chart. See Fig. 1.

Check continuity between terminals at Black wire connector
terminal on top of transfer case. With transfer control lever in "2H"
position, there should be no continuity. With transfer control lever
in "4H" position, there should be continuity. See Fig. 2.
Center Differential Lock Detection Switch (Montero)
Check continuity between terminals at Brown wire connector
terminal on side of transfer case. With transfer control lever in "4H"
position, there should be no continuity. With transfer control lever
in "4HLc" position, there should be continuity. See Fig. 2.
2WD-4WD Detection Switch (Montero)
Check continuity between terminals at Black wire connector
terminal on side of transfer case. With transfer control lever in "4H"
position, there should be no continuity. With transfer control lever
in "2H" position, there should be continuity. See Fig. 2.
HI/LO Detection Switch (Montero)
Check continuity between terminals at White wire connector
terminal on side of transfer case. With transfer control lever in "N"
(between "4HLc" and "4LLc") position, there should be no continuity.
With transfer control lever in "4HLc" position, there should be
continuity. With transfer control lever in "4LLc" position, there
should be continuity. See Fig. 2.
