3) Connect harness clamp to bracket.
4) Install ECM referring to “Engine Control Module (ECM) Removal and Installation in Section 1C”.
5) Connect negative cable at battery.
6) Bleed air from brake system referring to “Air Bleeding of Brake System in Section 4A”.
7) Check each installed part for fluid leakage.
8) For ESP

® model, perform “Sensor Calibration in Section 4F”.

9) Perform “Hydraulic Unit Operation Check”.

10) Turn ignition switch to OFF position once and then ON position. In this state, make sure that warning / indicator 

lights are turn off.

11) Check DTC(s) are not stored in hydraulic unit / control module.

Front Wheel Speed Sensor On-Vehicle 
Inspection

S6JB0B4506005

Output Voltage Inspection

1) Disconnect negative cable from battery.
2) Hoist vehicle a little.
3) Disconnect wheel speed sensor connector.
4) Disconnect wheel speed grommet from vehicle body.
5) Set up measuring devices as shown in figure, the 

resistance to 115 

Ω and the power supply voltage to 

12 V.

CAUTION

!

 

Incorrect voltage and/or wrong connection 
cause damage to wheel speed sensor.

 

6) Measure voltage at resistance without wheel 

rotation.
If voltage is out of specification, check sensor, 
mating encoder and their installation conditions.

Voltage at the resistance (115 

Ω) without wheel 

rotation
680 to 960 mV

7) Measure voltage at resistance with wheel rotation 

and confirm voltage alternately changes between 
high and low voltages.
If voltage does not change with wheel rotation, check 
sensor, mating encoder and their installation 
conditions.

Voltage at the resistance (115 

Ω) with wheel 

rotation
High voltage “a”: 1360 to 1930 mV
Low voltage “b”: 680 to 960 mV

Reference
When using oscilloscope for this check, check if peak-to-
peak voltage and waveform meet specification.

Peak-to-peak Voltage at the resistance (115 

Ω) with 

wheel rotation
High voltage “a”: 1360 to 1930 mV
Low voltage “b”: 680 to 960 mV

Front Wheel Speed Sensor Removal and 
Installation

S6JB0B4506006

CAUTION

!

 

• Do not pull wire harness when removing 

and installing front wheel speed sensor.

• Do not cause damage to surface of front 

wheel speed sensor and do not allow dust, 
etc. to enter its installation hole.

 

Removal

1) Disconnect negative cable from battery.
2) Disconnect front wheel speed sensor coupler (1).
3) Hoist vehicle and remove wheel.
4) Remove harness clamp, clamp bolts (2) and 

grommet (3).

5) Remove front wheel speed sensor (4) from knuckle.

Installation

1) Check that no foreign material is attached to sensor 

(1) and mating encoder (2).

2) Install it by reversing removal procedure.

Tightening torque
Front wheel speed sensor bolt (a):  11 N·m (1.1 
kgf-m, 8.0 lb-ft)
Front wheel speed sensor harness clamp bolt  
(b):  11 N·m (1.1 kgf-m, 8.0 lb-ft)

3) Check that there is no clearance between sensor 

and knuckle.

Front Wheel Speed Sensor Inspection

S6JB0B4506007

Check sensor for damage.
If any malcondition is found, replace.

Rear Wheel Speed Sensor On-Vehicle 
Inspection

S6JB0B4506008

Refer to “Front Wheel Speed Sensor On-Vehicle 
Inspection” since rear wheel speed sensor is the same 
as front wheel speed sensor.

Rear Wheel Speed Sensor Removal and 
Installation

S6JB0B4506009

CAUTION

!

 

• Do not pull wire harness when removing 

and installing rear wheel speed sensor.

• Do not cause damage to surface of rear 

wheel speed sensor and do not allow dust, 
etc. to enter its installation hole.

 

Removal

1) Disconnect negative cable from battery.
2) Disconnect rear wheel speed sensor coupler (1).
3) Hoist vehicle and remove wheel.
4) Remove harness clamp (4) and clamp bolts (2).
5) Remove rear wheel speed sensor (3) from knuckle.

Installation
Reverse removal procedure for installation noting the 
following.
• Check that no foreign material is attached to sensor 

(1) and mating encoder (2).

• Be sure to install wheel speed sensor (1) and its bolt 

at the correct (upper) position as shown in figure. 
Tighten sensor bolt and harness clamp bolts to 
specified torque.

Tightening torque
Rear wheel speed sensor bolt (a):  11 N·m (1.1 kgf-
m, 8.0 lb-ft)
Rear wheel speed sensor harness clamp bolt 
(b):  11 N·m (1.1 kgf-m, 8.0 lb-ft)

• Check that there is no clearance between sensor and 

brake back plate.
