NOTE:
The above figure (front side) shows left side. Right side is the mirror image.
REMOVAL
Pay attention to the following when removing sensor.
CAUTION:

Do not twist sensor harness as much as possible, when removing it. Pull sensors out without pull-
ing on sensor harness.

Take care to avoid damaging sensor edges or rotor teeth. Remove wheel sensor first before
removing front or rear wheel hub. This is to avoid damage to sensor wiring and loss of sensor
function.
INSTALLATION
Pay attention to the following when installing wheel sensor. Tighten installation bolts 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 the figure. When installed, harness must not be twisted.

Removal and InstallationNFS000RC
COMPONENT
CAUTION:
Be careful of the following.

Before servicing, disconnect the battery cable from negative terminal.

To remove brake tube, use a flare nut wrench to prevent flare nuts and brake tube from being dam-
aged. To install, use flare nut torque wrench.

Do not apply excessive impact to ABS actuator and electric unit (control unit), such as dropping it.

Do not remove and install actuator by holding harness.

After work is completed, bleed air from brake tube. Refer to BR-10, "Bleeding Brake System" .

After installing harness connector in the ABS actuator and electric unit (control unit), make sure
connector is securely locked.
REMOVAL
1. Remove cowl top cover. Refer to EI-18, "REMOVAL" .
2. Disconnect ABS actuator and electric unit (control unit) connector.
3. Loosen brake tube flare nuts, then remove brake tubes from ABS actuator and electric unit (control unit).
4. Remove tire.
5. Remove fender protector (rear): (front LH side). Refer to EI-20, "
REMOVAL" .
6. Remove ABS actuator and electric unit (control unit) bracket mounting nut.

CAUTION:

Do not drop or strike yaw rate/side G sensor, because it has little endurance to impact.

Do not use power tool etc., because yaw rate/side G sensor is sensitive for the impact.
REMOVAL
1. Remove center console. Refer to IP-10, "Component Parts
Drawing" .
2. Disconnect yaw rate/side G sensor harness connector.
3. Remove mounting bolts. Remove yaw rate/side G sensor (1).

WATER INLET AND THERMOSTAT ASSEMBLY
Revision: 2007 April2007 M35/M45
INSPECTION AFTER REMOVAL
1. Check valve seating condition at ordinary room temperatures. It should seat tightly.
2. Check valve operation.

If the malfunctioning condition, when valve seating at ordinary
room temperature, or measured values are out of the standard,
replace water inlet and thermostat assembly.
INSTALLATION
Note the following, and install in the reverse order of removal.

Be careful not to spill engine coolant over engine room. Use rag to absorb engine coolant.
INSPECTION AFTER INSTALLATION

Check for leaks of engine coolant using the radiator cap tester adapter (commercial service tool) and the
radiator cap tester (commercial service tool). Refer to CO-11, "
LEAK CHECK" .

Start and warm up the engine. Visually make sure that there is no leaks of engine coolant.
