Repair procedures
1. |
Remove the rear wheel & tire.
Tightening torque:
107.9 - 127.5 N·m (11.0 - 13.0 kgf·m, 79.6 - 94.0 lb·ft)
|
|
2. |
Disconnect the rear wheel speed sensor.
|
3. |
Loosen the nut (A) and bolt (B).
Tightening torque:
(A) 8.8 - 13.7 N·m (0.9 - 1.4 kgf·m, 6.5 - 10.1 lb·ft)

4. |
Remove the rear seat.
(Refer to body -"Rear Seat Assembly")
|
5. |
Remove the door scuff trim.
(Refer to body -"Door Scuff Trim")
|
6. |
Disconnect the rear wheel speed sensor connector.
|
1. |
Measure the output voltage between the terminal of the wheel speed sensor
and the body ground.
In order to protect the wheel speed sensor, when measuring output
voltage, a 100 Ω resister must be used as shown.
|
|
2. |
Compare the change of the output voltage of the wheel speed sensor to
the normal change of the output voltage as shown below.
V_low : 0.59V - 0.84V
V_high : 1.18V - 1.68V
Frequency range : 1 - 2,500Hz

1. |
Remove the rear wheel hub bearing assembly.
(Refer to Driveshaft and axle - "Rear Axle Assembly")
|
2. |
Fix the rear hub bearing assembly (A) on the vise.
•
|
When fixing on the vise, use a cloth not to be damaged
the hub bearing assembly.
|
•
|
Be careful if excessive force for fixing on the vise
may damage the hub bearing assembly.
|
|
|
3. |
Check the direction of the sensor cap (A).
Before removing the sensor cap, check the direction of the sensor
cap connector.
|
|
4. |
Remove the sensor cap by hammering on a gap between sensor cap and hub
bearing assembly using a scraper (A).
•
|
In order to widen the gap little by little, hammering
around the bearing cap 10-20 times.
|
•
|
When removing the sensor cap, remove it in a straight
direction not to damage the tone wheel or encoder.
|
•
|
Be careful not to damage the hub bearing assembly when
using the hammer.
|
|
|
5. |
Check if distorted or damaged the tone wheel or encoder (A).
•
|
Check if damaged the tone wheel or encoder after removing
the sensor cap and replace the hub bearing if it was deformed.
|
•
|
If the tone wheel is deformed, it may arise MIL ON or
other problems.
|
|
|
6. |
Position the sensor cap to the same direction of sensor cap connector
(A) as you checked before removing.
Before installing the sensor cap, do not let any foreign material
and contaminant into the hub bearing assembly.
|
|
7. |
Install the sensor cap (A) with the special service tool (09527-1S010).
•
|
Be careful not to tilt to one side when installing the
sensor cap as it may damage the tone wheel or encoder.
|
•
|
When sensor cap installation, hammering it until the
gap disappeared between the sensor cap and hub bearing assembly.
