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.

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-11, "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.

Tighten fuel hose clamps to the specified torque.
Do not depress accelerator pedal when starting.
Immediately after starting, do not rev up engine unneces-
sarily.
Do not rev up engine just prior to shutdown.
When installing C.B. ham radio or a mobile phone, be sure
to observe the following as it may adversely affect elec-
tronic control systems depending on installation location.
–Keep the antenna as far as possible from the electronic
control units.
–Keep the antenna feeder line more than 20 cm (8 in) away
from the harness of electronic controls.
Do not let them run parallel for a long distance.
–Adjust the antenna and feeder line so that the standing-
wave radio can be kept smaller.
–Be sure to ground the radio to vehicle body.

Revision: 2006 January2006 M35/M45
DTC P0011, P0021 IVT CONTROLPFP:23796
DescriptionNBS004TT
SYSTEM DESCRIPTION
*: This signal is sent to the ECM through CAN communication line
This mechanism hydraulically controls cam phases continuously with the fixed operating angle of the intake
valve.
The ECM receives signals such as crankshaft position, camshaft position, engine speed, and engine coolant
temperature. Then, the ECM sends ON/OFF pulse duty signals to the intake valve timing (IVT) control sole-
noid valve depending on driving status. This makes it possible to control the shut/open timing of the intake
valve to increase engine torque in low/mid speed range and output in high-speed range.
