WIRING DIAGRAM COMPONENT LOCATIONS
When trying to locate a component in a wiring diagram and you
don't know the specific system where it is located, use this handy
component locator to find the system wiring diagram in which the
component is located. Then, go to that system and locate the component
within the wiring diagram.
For example, if you don't know the specific system in which
the ignition switch is located, look up ignition switch in the wiring
diagram component location tables and go to the appropriate wiring
diagram(s) which contain either full or partial views of the ignition
switch. The full view of the ignition switch is located in Power
Distribution.
The first listing for the component will be the full or most
complete view of the component. Additional listings will be partial
views of the component. Not all components are used on all models.
All components will have a partial view in Ground
Distribution and Power Distribution. Data Link Connectors show
connecting circuits between modules. Alternate names for components
may be listed in wiring diagram component locations tables.

PCV Valve
Remove PCV valve. Shake valve. Valve should rattle if moving
freely. Apply air pressure to valve. Air should flow freely in one
direction only. Connect PCV valve to vacuum hose and start engine.
Ensure vacuum is flowing through valve.
MISCELLANEOUS CONTROLS
NOTE: Although the controlled devices listed here are not
technically engine performance components, they can affect
driveability if they malfunction.
NOTE: To identify PCM A/C power supply voltage terminals, see
appropriate pin voltage chart in J - PIN VOLTAGE CHARTS
article. To identify PCM A/C power supply circuit, see
appropriate wiring diagram in L - WIRING DIAGRAMS article.
A/C Switch & Compressor Clutch Relay
Using DVOM, check A/C power supply voltage from PCM. Turn
ignition switch to OFF position. Disconnect PCM connector. Turn A/C
switch and ignition switch to ON position. Check voltage between PCM
A/C power supply terminal and chassis ground. If battery voltage is
not as present, check and repair circuit(s).

LOCKING HUBS
1998 Mitsubishi Montero
1997-98 DRIVE AXLES
Mitsubishi Locking Hubs
Montero, Montero Sport
DESCRIPTION
Vehicles are equipped with an automatic locking clutch.
Locking clutch engages, providing full time AWD operation, when 4WD
(4H) is selected at transfer case, at speeds up to 62 MPH. Selecting
center differential lock position (4HLc or 4HLLc), while in AWD at 4
MPH or less, provides 4WD operation. Center differential lock
disengages when 4H or 2H is selected. Locking clutch disengages when
2H is selected.
REMOVAL & INSTALLATION
AUTOMATIC LOCKING HUBS
Removal & Installation
1) Remove right side inner shaft for automatic locking clutch
removal. See INNER SHAFT & BEARING in
DIFFERENTIAL & AXLE SHAFTS - FRONT article. With inner shaft removed,
remove locking clutch engage switch. See Fig. 1.
2) Remove 4 inner shaft tube-to-differential mounting bracket
bolts. Pivot differential mounting bracket. Remove 4 inner shaft tube-
to-differential carrier assembly mounting bolts. Pull inner shaft tube
and automatic locking clutch out of differential carrier assembly.
3) To install, reverse removal procedure. Tighten inner shaft
tube bolts to 65 ft. lbs. (90 N.m) and locking clutch engage switch to\
26 ft. lbs.(36 N.m).
