BODY ELECTRICAL COMBINATION METER
1996 LAND CRUISER (RM451U)
INSPECTION
1. INSPECT SPEEDOMETER ON−VEHICLE:
Using a speedometer tester, inspect the speedometer for allow-
able indication error and check the operation of the odometer.
HINT:
Tire wear and tire over or under inflation will increase the indica-
tion error.
If error is excessive, replace the speedometer.
Standard indicationAllowable range
2018 − 24
4038 − 44
6058 − 66
8078 − 88
10098 − 11 0
120118 − 132
2. INSPECT NO.1 VEHICLE SPEED SENSOR OPERA-
TION
(a) Connect the positive (+) lead from battery to terminal 1 and negative ( −) lead to terminal 2.
(b) Connect the positive (+) lead from tester to terminal 3 and
the negative ( −) lead to terminal 2.
(c) Revolve shaft.
(d) Check that there is voltage changer from approx. 0 V to 11 V or more between terminals 3 and 2.
HINT:
The voltage change should be 4 times per each revolution of
the No.1 vehicle speed sensor shaft.
If operation is not as specified, replace the sensor.
3. INSPECT TACHOMETER ON−VEHICLE:
(a) Connect a tune− up test tachometer, and start the engine.
NOTICE:
Reversing the connection of the tachometer will damage
the transistors and diodes inside.When removing or instal-
ling the tachometer, be careful not to drop or subject it to
heavy shocks.
(b) Compare the tester and tachometer indications.
If error is excessive, replace the tachometer.

REMOVAL
HINT:
When replacing the sensor or sensor harness, replace the sen-
sor and sensor harness together as a set.
1. DISCONNECT SPEED SENSOR CONNECTOR
2. REMOVE SPEED SENSOR
(a) Remove the 8 clamp bolts holding the sensor harness
from the axle housing.
(b) Remove the bolt and wire tie holding the sensor harness from the stabilizer bar.
(c) Remove the bolt and 2 clips holding the sensor harness
from the frame and body.
(d) Remove the 2 installation bolts and speed sensors from the steering knuckle.

BRAKE FRONT SPEED SENSOR
1996 LAND CRUISER (RM451U)
INSPECTION
1. INSPECT SPEED SENSOR
(a) Disconnect the speed sensor connector.
(b) Measure the resistance between terminals FR+ and FR −,
and FL+ and FL−.
Resistance: 0.5 − 1.6 kΩ
If resistance value is not specified, replace the sensor.
(c) Check there is no continuity between each terminal and sensor body.
If there is continuity, replace the sensor.
(d) Connect the speed sensor connector.
2. INSPECT SENSOR INSTALLATION
Check the sensor installation bolt is tightened properly and
there is no clearance between the sensor and axle end.
If not, tighten the bolt. Torque: 18 N·m (185 kgf·cm, 13 ft·lbf)
3. VISUALLY INSPECT SENSOR ROTOR SERRATIONS
(a) Remove the axle hub with disc (See page SA−67).
(b) Inspect the sensor rotor serrations for scratches, cracks,
warping or missing teeth.
(c) Install the axle hub with disc SA−9 ).
NOTICE:
To prevent damage to the serrations, do not strike the axle
hub.
