BRAKE ABS ACTUATOR
1996 LAND CRUISER (RM451U)
INSPECTION
1. INSPECT CONTINUITY OF MOTOR RELAY CIRCUIT
(a) Check there is continuity between terminals 9 and 10.
(b) Check there is no continuity between terminals 7 and 8.
If continuity is not as specified, replace the relay.
2. INSPECT OPERATION OF MOTOR RELAY CIRCUIT
(a) Connect the positive (+) lead from the battery to terminal 10 and negative ( −) lead to terminal 9.
(b) Check there is continuity between terminals 7 and 8.
If operation is not as specified, replace the relay.
3. INSPECT CONTINUITY OD SOLENOID RELAY CIR- CUIT
(a) Check there is continuity between terminals 1 and 9.
(b) Check there is no continuity between terminals 2 and 5.
(c) Connect the positive lead from the ohmmeter to terminal 5 and connect negative lead to terminal 4.
(d) Check there is continuity between terminals.
(e) Connect the 2 leads in reverse, and check that there is no
continuity between terminals.
If continuity is not as specified, replace the relay.
HINT:
For the different type ohmmeter, there is no continuity for step
(d), and there is continuity for step (e).
4. INSPECT OPERATION OF SOLENOID RELAY CIR- CUIT
(a) Connect the positive (+) lead from the battery to terminal
1 and negative ( −) lead to terminal 9.
(b) Check there is continuity between terminal 2 and 6.
(c) Check there is no continuity between terminals 2 and 6.
If operation is not as specified, replace the relay.

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.
Torque: 18 N·m (185 kgf·cm, 13 ft·lbf)

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.
