DIAGNOSTICS ANTI-LOCK BRAKE SYSTEM

1996 LAND CRUISER (RM451U)
DTC31, 32, 33, 34, 35, 36 Speed Sensor Circuit
CIRCUIT DESCRIPTION
The speed sensor detects wheel speed and sends the ap-
propriate signals to the ECU. These signals are used to control
the ABS system. The front and rear rotors each have 48 serra-
tions.
When the rotors rotate, the magnetic field emitted by the perma-
nent magnet in the speed sensor generates an AC voltage.
Since the frequency of this AC voltage changes in direct propor-
tion to the speed of the rotor, the frequency is used by the ECU
to detect the speed of each wheel.
DTC No.DTC Detecting ConditionTrouble Area
31, 32, 33, 34
Detection of any of conditions (1) through (3):
(1) At vehicle speed of 10 km/h (6 mph) or more, pulses are
not input for 5 sec.
(2) Momentary interruption of the speed sensor signal oc-
curs at least 7 times in the time between switching the igni-
tion switch ON and switching it OFF.
(3) Abnormal fluctuation of speed sensor signals with the
vehicle speed 20 km/h (12 mph) or more.

Speed sensor signal is not input for about 1 sec. while
the left front and right rear speed sensor signals are being
checked with the IG switch ON.

Open in left front or right rear speed sensor circuit
36
Speed sensor signal is not input for about 1 sec. while
the right front and left rear speed sensor signals are being
checked with the IG switch ON.

Open in right front or left rear speed sensor circuit
HINT:

DTC No. 31 is for the right front speed sensor.

DTC No. 32 is for the left front speed sensor.

DTC No. 33 is for the right rear speed sensor.

DTC No. 34 is for the left rear speed sensor.
Fail safe function:
If trouble occurs in the speed sensor circuit, the ECU cuts off current to the ABS control (solenoid) relay and
prohibits ABS control.

COMPRESSION
INSPECTION
HINT:
If there is lack of power, excessive oil consumption or poor fuel
economy, measure the compression pressure.
1. WARM UP AND STOP ENGINE
Allow the engine to warm up to normal operating temperature.
2. DISCONNECT DISTRIBUTOR CONNECTOR
3. REMOVE SPARK PLUGS (See page IG−1 )
4. CHECK CYLINDER COMPRESSION PRESSURE
(a) Insert a compression gauge into the spark plug hole.
(b) Fully open the throttle.
(c) While cranking the engine, measure the compression pressure.
HINT:
Always use a fully charged battery to obtain engine speed of
250 rpm or more.
(d) Repeat steps (a) through (c) for each cylinder.
NOTICE:
This measurement must be done in as short a time as pos-
sible. Compression pressure:
1,176 kPa (12.0 kgf/cm
2, 171 psi) or more
Minimum pressure: 883 kPa (9.0 kgf/cm
2, 128 psi)
Difference between each cylinder:
98 kPa (1.0 kgf/cm
2, 14 psi) or less
If the cylinder compression in one or more cylinders is low, pour
a small amount of engine oil into the cylinder through the spark
plug hole and repeat steps (a) through (c) for cylinders with low
compression.
If adding oil helps the compression, it is likely that
the piston rings and/or cylinder bore are worn or
damaged.
If pressure stays low, a valve may be sticking or
seating is improper, or there may be leakage past
the gasket.
5. REINSTALL SPARK PLUGS (See page IG−1 )
6. RECONNECT DISTRIBUTOR CONNECTOR

15. CHECK THRUST CLEARANCE OF OIL PUMP DRIVE
SHAFT GEAR
Using a dial indicator with lever type attachment, measure the
thrust clearance.
Standard thrust clearance:
0.040 − 0.160 mm (0.0016 − 0.0063 in.)
Maximum thrust clearance: 0.30 mm (0.0118 in.)
If the thrust clearance is greater than maximum, replace the oil
pump drive shaft gear and/or timing chain cover.
16. REMOVE DRIVE BELT IDLER PULLEY
Remove the bolt and idler pulley.
17. REMOVE TIMING CHAIN COVER
(a) Remove the 9 mounting bolts, 2 mounting nuts and drive belt adjusting bar.
(b) Remove the oil pump by prying the portions between the cylinder block and oil pump with a screwdriver.
NOTICE:
Be careful not to damage the contact surfaces of the cylin-
der block and oil pump.
(c) Remove the O−rings from the oil pump.
(d) Remove the gasket from the oil pump.
18. REMOVE TIMING CHAIN AND CAMSHAFT TIMING GEAR

INSPECTION
1. INSPECT TIMING CHAIN AND TIMING GEARS
(a) Measure the length of 16 links with the chain fully
stretched.
Maximum chain elongation: 146.6 mm (5.772 in.)
If the elongation is greater than maximum, replace the chain.
HINT:
Make the same measurements pulling at 3 or more places se-
lected at random.
(b) Wrap the chain around the timing gear.
(c) Using vernier calipers, measure the timing gear diameter with the chain.
NOTICE:
Vernier calipers must contact the chain rollers for measur-
ing.
Minimum gear diameter (w/Chain):
Camshaft126.0 mm (4.961 in.)
Crankshaft65.4 mm (2.575 in.)
If the diameter is less than minimum, replace the chain and
gears.
2. INSPECT CHAIN TENSIONER SLIPPER AND VIBRA-TION DAMPER
Measure the chain tensioner slipper and vibration damper
wears. Maximum wear: 1.0 mm (0.039 in.)
If the wear is greater than maximum, replace the slipper and/or
damper.
3. INSPECT OIL JET
Check the oil jet for damage or clogging.
If necessary, replace the oil jet.
