WIRING DIAGRAM
INSPECTION PROCEDURE
1 READ VALUE ON INTELLIGENT TESTER (REAR SPEED SENSOR)
(a) Connect the intelligent tester to the DLC3.
(b) Start the engine.
(c) Select the DATA LIST mode on the intelligent tester.
ABS / VSC:
(d) Check that there is no difference between the speed value output from the speed sensor displayed by the intelligent tester and the speed value displayed on the speedometer when driving the vehicle
OK: There is almost no difference in the displayed speed value.
HINT: There is tolerance of +- 10 % in the speedometer indication.
2 CHECK SPEED SENSOR AND SENSOR ROTOR SERRATIONS
(a) INSPECTION USING OSCILLOSCOPE:
(1) Connect the oscilloscope to terminals RR+ - RR- or RL+ - RL- of the skid control ECU.
(2) Drive the vehicle at approximately 19 mph (30 km/ h), and check the signal waveform.
OK: A waveform as shown in a figure should be output.
HINT:
NOTICE: When replacing the brake actuator assembly, perform zero point calibration (See page BC-70).
REPLACE BRAKE ACTUATOR ASSEMBLY
3 INSPECT REAR SPEED SENSOR
(a) 2WD
(1) Disconnect the skid control sensor connector.
(2) Measure the resistance according to the value(s) in the table below.
Standard resistance:
LH
RH
NOTICE: Check the speed sensor signal after replacement (See page BC-72).
(b) 4WD
(1) Remove the seat cushion seatback.
(2) Disconnect the speed sensor connector.
(3) Measure the resistance according to the value(s) in the table below.
Standard resistance:
LH
RH
(4) Measure the resistance according to the value(s) in the table below
Standard resistance:
LH
RH
NOTICE: Check the speed sensor signal after the replacement. (See page BC-72)
4 CHECK HARNESS AND CONNECTOR (REAR SPEED SENSOR - SKID CONTROL ECU)
(a) Disconnect the skid control ECU connector and the skid control sensor connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:
LH
RH
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance:
LH
RH
5 CHECK SPEED SENSOR AND SENSOR ROTOR SERRATIONS
(a) INSPECTION USING OSCILLOSCOPE
(1) Connect the oscilloscope to terminals RR+ - RR- or RL+ - RL- of the skid control ECU.
(2) Drive the vehicle at approximately 19 mph (30 km/ h), and check the signal waveform.
OK: A waveform as shown in a figure should be output.
HINT:
NOTICE: When replacing the brake actuator assembly, perform zero point calibration (See page BC-70).
REPLACE BRAKE ACTUATOR ASSEMBLY
6 CHECK REAR SPEED SENSOR INSTALLATION
(a) 2WD
(1) Check the sensor installation.
OK: There is no clearance between the sensor and rear axle carrier.
(b) 4WD
(1) Check the sensor installation.
OK: There is no clearance between the sensor and rear axle carrier.
The installation bolt is tightened properly.
Torque: 8.0 N*m (82 kgf*cm, 71 in.*lbf)
NOTICE: Check the speed sensor signal after the replacement (See page BC-72).
7 CHECK SPEED SENSOR ROTOR
(a) Remove the rear axle hub and bearing, or rear drive shaft (See page AH-16 for 2WD, or DS-21 for 4WD).
(b) Check the sensor rotor serrations.
OK: No scratches, missing teeth or foreign objects.
Result
NOTICE: Check the speed sensor signal after the replacement (See page BC-72).
8 CHECK REAR SPEED SENSOR TIP
(a) Remove the rear speed sensor (See page BC-190 for 2WD or BC-194 for 4WD).
(b) Check the sensor tip.
OK: No scratches or foreign matter on the sensor tip.
NOTICE:
REPLACE BRAKE ACTUATOR ASSEMBLY
Installation
1. INSTALL REAR AXLE HUB & BEARING ASSEMBLY LH
(a) Install the hub & bearing assembly LH with the 4
bolts.
Torque: 56 N*m (571 kgf*cm, 41 ft.*lbf)
2. INSPECT BEARING BACKLASH (See page AH-19)
3. INSPECT AXLE HUB DEVIATION (See page AH-19)
4. INSTALL REAR DRIVE SHAFT ASSEMBLY LH (Se ...
