unit. Turn ignition on. Check voltage between ground and sending unit
harness-side connector. If battery voltage is present, problem is
intermittent. If battery voltage is not present, go to next step.
2) Check sending unit harness connector. Repair as necessary.
If connector is okay, check circuit (Yellow wire) between oil pressure\
gauge and oil pressure sending unit. See WIRING DIAGRAMS. Repair as
necessary. If circuit is okay, go to next step.
3) Remove multi-meter assembly. Check voltage between ground
and harness-side connector terminal No. 10 (Red/Black wire). See
WIRING DIAGRAMS . If battery voltage is present, problem is
intermittent. If battery voltage is not present, go to next step.
4) Check harness connector to multi-meter assembly. Repair as
necessary. If connector is okay, check circuit between multi-meter
harness connector and fusible link No. 6. See WIRING DIAGRAMS. Repair
as necessary. If circuit is okay, go to next step.
5) Turn ignition on. Check voltage between ground and multi-
meter harness-side connector terminal No. 11 (Black/White wire). See
WIRING DIAGRAMS . If battery voltage is present, problem is
intermittent. If battery voltage is not present, go to next step.
6) Check harness connector to multi-meter assembly. Repair as
necessary. If connector is okay, check circuit between multi-meter
assembly harness connector and ignition switch. See WIRING DIAGRAMS.
Repair as necessary. If circuit is okay, go to next step.
7) Turn ignition off. Check continuity between ground and
multi-meter assembly harness-side connector terminal No. 3 (Black
wire). If continuity is present, problem is intermittent. If
continuity is not present, go to next step.
8) Check harness connector to multi-meter assembly. Repair as
necessary. If connector is okay, check circuit (Black wire) between
multi-meter assembly harness connector and ground. See WIRING DIAGRAMS
. Repair as necessary. If circuit is okay, problem is intermittent.
Gauge Sending Unit Resistance Test (Montero Sport)
Disconnect harness connector to oil pressure sending unit.
Start and idle engine. Check resistance between oil pressure gauge
sending unit terminal and engine block. Resistance should be about 2
ohms. Replace sending unit if resistance is not as specified.
REED SWITCH
Continuity Check (Montero)
1) Remove instrument cluster. See INSTRUMENT CLUSTER under
REMOVAL & INSTALLATION. Check continuity between reed switch terminals
No. 1 and 2. See Fig. 20.
2) Ensure continuity pulses on and off 4 times per revolution
of speedometer shaft connection. If continuity is not as specified,
replace reed switch.

Belts or components should be inspected and replaced if any
of the following conditions exist:
* Cracks Or Tears In Belt Surface
* Missing, Damaged, Cracked Or Rounded Teeth
* Oil Contamination
* Damaged Or Faulty Tensioners
* Incorrect Tension Adjustment

WHEEL & TIRE SPECIFICATIONS
Tire specifications are imprinted on the tire side wall. The
recommended cold tire inflation pressures are listed on a label
attached to the rear face of the driver's door. These pressures
provide the best combination of ride comfort, tire wear and stability
under normal conditions.
CAUTION: DO NOT mix tires of different design such as radial ply
with bias or bias-belted tires. Mixing tire types will
adversely affect road handling and may lead to loss of
vehicle control. When using snow tires, they must be used
in set of four for maneuverability and safety. DO NOT use
tire chains on front wheels.

allowing metal objects to contact the battery posts and the
vehicle at the same time.
CAUTION: Never disconnect the battery while the engine is running;
doing so could damage the car's electrical components.
REPLACING BLOWN FUSES
Before replacing a blown fuse, remove ignition key, turn off
all lights and accessories to avoid damaging the electrical system. Be
sure to use fuse with the correct indicated amperage rating. The use
of an incorrect amperage rating fuse may result in a dangerous
electrical system overload.
BRAKE PAD WEAR INDICATOR
Indicator will cause a squealing or scraping noise, warning
that brake pads need replacement.
BRAKE FLUID
WARNING: DO NOT use reclaimed fluid or fluid that has been stored
in old or open containers. It is essential that foreign
particles and other liquids are kept out of the brake fluid
reservoir.
CATALYTIC CONVERTER
Continued operation of vehicle with a severe malfunction
could cause converter to overheat, resulting in possible damage to
converter and vehicle.
ENGINE COOLANT SERVICE
WARNING: To avoid the danger of being scalded never change the coolant
when the engine is hot.
WARNING: Never remove the radiator cap when the engine is hot Serious
burns could be caused by high pressure fluid escaping from
the radiator.
CAUTION: When adding or replacing engine coolant, use a high quality
ethylene glycol antifreeze diluted with 50% distilled water.
When putting the cap on the reserve tank, line up the arrow
on the cap and the arrow on the tank, or coolant can leak out
ENGINE DRIVE BELT SERVICE
WARNING: Be sure the ignition key is OFF. The engine could rotate
unexpectedly.
ENGINE OIL
WARNING: The engine oil may be high enough to burn your fingers
when the drain plug is loosened. Wait until the drain plug
is cool enough to touch with you bare hands.
WARNING: Continuous contact with used engine oil has been found to
cause skin cancer in laboratory animals. Brief contact with
used engine oil may irritate skin. To minimize your exposure
to used oil, wear a long sleeve shirt and moisture-proof
gloves when changing oil. If oil contacts your skin, wash
Page 969 of 1501
thoroughly with soap and water.
CAUTION: Never use non-detergent or straight mineral oil.
FUEL SYSTEM SERVICE
WARNING: Relieve fuel system pressure prior to servicing any fuel
system component (fuel injection models).
HALOGEN BULBS
Halogen bulbs contain pressurized gas which may explode if
overheated. DO NOT touch glass portion of bulb with bare hands. Eye
protection should be worn when handling or working around halogen
bulbs.
RADIATOR CAP
CAUTION: Always disconnect the fan motor when working near the
radiator fan. The fan is temperature controlled and could
start at any time even when the ignition key is in the OFF
position. DO NOT loosen or remove radiator cap when cooling
system is hot.
RADIATOR FAN
WARNING: Keep hands away from radiator fan. Fan is controlled by a
thermostatic switch which may come on or run for up to 15 minutes even
after engine is turned off.
WARRANTY INFORMATION
CAUTION: Due to the different warranties offered in various regions
and the variety of after-market extended warranties
available, please refer to the warranty package that came
with the vehicle to verify all warranty options.
FUSES & CIRCUIT BREAKERS
FUSE PANEL LOCATION
The electrical system is protected against shorts by fuses
that are designed to fail, to prevent damage to the wire harness. The
fuse block is located under the instrument panel on the driver's side.
If a fuse is blown, locate the cause before replacing the fuse. Spare
fuses are contained in the fuse block.
