Removal and Installation
AFS0020R
REMOVAL
Pay attention to the following when removing wheel sensor.
CAUTION:
●
As much as possible, avoid rotating wheel sensor when removing it. Pull wheel sensors out with-
out pulling on sensor harness.
●
Take care to avoid damaging wheel sensor edges or rotor teeth. Remove wheel sensor first before
removing front or rear wheel hub. This is to avoid damage to wheel sensor wiring and loss of sen-
sor function.
INSTALLATION
Pay attention to the following when installing wheel sensor. Tighten installation bolts and nuts to the specified
torques.
●
When installing, make sure there is no foreign material such as iron chips on and in the mounting hole of
the wheel sensor. Make sure no foreign material has been caught in the sensor rotor. Remove any foreign
material and clean the mount.
●
When installing wheel sensor, be sure to press rubber grommets in until they lock at locations shown
above in figure. When installed, harness must not be twisted.

Pay attention to the following when removing actuator.
CAUTION:
●
If the part number on the part number label (pasted on actuator upper surface) is the same, VDC/
TCS/ABS actuator (integrated in control unit, part No. : 47660 *****) cannot be used on another
vehicle.
If it is used on another vehicle, ABS warning lamp, SLIP indicator lamp, VDC OFF indicator lamp
may turn ON or VDC/TCS/ABS may not operate normally.
When replacing VDC/TCS/ABS actuator (integrated in control unit), must use new service parts.
●
Before servicing, disconnect battery cables.
●
To remove brake tube, use flare nut wrench to prevent flare nuts and brake tube from being dam-
aged. To install, use flare nut wrench (commercial service tool).
●
Do not remove and install actuator by holding harness.
●
After work is completed, bleed air from brake piping. Refer to
BR-12, "Bleeding Brake System"
NOTE:
●
After performing above works, calibrate decel G-sensor (AWD model). Refer to
