System Components
System Description
WHEEL SENSOR
The sensor unit consists of a gear-shaped sensor rotor and a
sensor element. The element contains a bar magnet around
which a coil is wound. The sensor is installed on the back of the
brake rotor and the front of the differential (2WD) or the back of
the rear brake drum (4WD). As the wheel rotates, the sensor
generates a sine-wave pattern. The frequency and voltage
increase(s) as the rotating speed increases.
CONTROL UNIT (built in ABS actuator and electric
unit)
The control unit computes the wheel rotating speed by the sig-
nal current sent from the sensor. Then it supplies a DC current
to the actuator solenoid valve. It also controls ON-OFF operation
of the valve relay and motor relay. If any electrical malfunction
should be detected in the system, the control unit causes the
warning lamp to light up. In this condition, the ABS will be deac-
tivated by the control unit, and the vehicle's brake system reverts
to normal operation. (For control unit layout, refer to ABS
ACTUATOR AND ELECTRIC UNIT, BR-34.)

Removal
1. Raise vehicle and support it with safety stands.
2. Remove engine under cover.
3. Drain engine oil.
4. Remove front final drive together with differential mounting
member. Refer to PD section (``Removal and Installation'',
``Front final drive'') Ð 4WD models only.
5. Remove front suspension member bolt (RH & LH).
6. Remove oil pan bolts.
7. Remove oil pan.
a. Insert Tool between cylinder block and oil pan.
lBe careful not to damage aluminum mating surface.
lDo not insert screwdriver, or oil pan flange will be dam-
aged.
b. Slide Tool by tapping on the side of the Tool with a hammer.
8. Pull out oil pan from front side.

Measurement of Compression Pressure
1. Warm up engine.
2. Stop engine. Remove glow plate and glow plugs.
3. Fit compression gauge adapter to cylinder head.
Compression gauge adapter:
:15-20Nzm (1.5 - 2.0 kg-m, 11 - 14 ft-lb)
4. Disconnect fuel cut solenoid wire connector.
5. Crank engine, then read gauge indication.
lEngine compression measurement should be made as
quickly as possible.
Compression pressure:
Unit: kPa (bar, kg/cm2, psi)/200 rpm
Standard 2,942 (29.4, 30, 427)
Minimum 2,452 (24.5, 25, 356)
Differential limit between cylinders 294 (2.9, 3, 43)
6. If cylinder compression in one or more cylinders is low, pour
a small quantity of engine oil into cylinders through the glow
holes and retest compression.
lIf adding oil helps the compression pressure, chances
are that piston rings are worn or damaged.
lIf pressure stays low, valve may be sticking or seating
improperly.
lIf cylinder compression in any two adjacent cylinders is
low, and if adding oil does not help the compression,
there is leakage past the gasketed surface.
Oil and water in combustion chambers can result from
this problem.

WARNING:
lPlace vehicle on a flat and solid surface.
lPlace chocks at front and rear of rear wheels.
lYou should not remove oil pan until exhaust system and
cooling system have completely cooled off.
Otherwise, you may burn yourself and/or fire may break
out in the fuel line.
lWhen removing front and/or rear engine mounting bolts
or nuts, lift up slightly engine for safety work.
CAUTION:
lIn lifting engine, be careful not to hit against adjacent
parts, especially against accelerator wire casing end,
brake tube and brake master cylinder.
lFor tightening torque, refer to EM-71, MT and PD sec-
tions.
Remove oil pan bolts in order shown.
Installation
1. Install the oil pan gasket with the coated surface facing the
cylinder block and the notch facing the rear of the engine.
2. Tighten all bolts in reverse order of removal. For tightening
torque of oil pan and correct installing direction of drain plug
washer, refer to EM-71.
