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.
Refer to BRC-57, "

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.

COMBINATION METERS
Revision: 2006 January2006 M35/M45
SPEEDOMETER
The speedometer indicates the vehicle speed.
ABS actuator and electric unit (control unit) converses a pulse signal from wheel sensor to vehicle speed
signal, and transmit vehicle speed signal to unified meter and A/C amp. with CAN communication.
Unified meter and A/C amp. transmits vehicle speed signal to combination meter with communication line.
Combination meter converses vehicle speed signal to the angle signal, and commands to speedometer.
TACHOMETER
The tachometer indicates engine speed in revolutions per minute (rpm).
ECM converses a signal from crankshaft position sensor to engine speed signal, and transmits to unified
meter and A/C amp. with CAN communication.
Unified meter and A/C amp. transmits engine speed signal to combination meter with communication line.
Combination meter converses engine speed signal to the angle signal, and commands to tachometer.
WATER TEMPERATURE GAUGE
The water temperature gauge indicates the engine coolant temperature.
ECM converses a signal from engine coolant temperature sensor to engine coolant temperature signal,
and transmits to unified meter and A/C amp. with CAN communication.
Unified meter and A/C amp. transmits engine coolant temperature signal to combination meter with com-
munication line.
Combination meter converses engine coolant temperature signal to the angle signal, and commands to
water temperature gauge.

FUEL GAUGE
The fuel gauge indicates the approximate fuel level in the fuel tank.
The fuel gauge is regulated by a variable ground signal supplied
from unified meter and A/C amp. terminal 58
through the fuel level sensor unit and fuel pump (main) terminals 5 and 2, and
through the fuel level sensor unit (sub) terminals 2 and 1
to unified meter and A/C amp. terminal 42.
Unified meter and A/C amp. provides a fuel level signal to combination meter for fuel gauge with communica-
tion line between unified meter and A/C amp. and combination meter.
ODO/TRIP METER
ABS actuator and electric unit (control unit) converses a pulse signal from wheel sensor to vehicle speed
signal, and transmits vehicle speed signal to unified meter and A/C amp. with CAN communication.
Unified meter and A/C amp. converses vehicle speed signal to 8 pulse signal, and transmits to combina-
tion meter.
Combination meter processes the 8 pulse signal and the memory signals from the meter memory circuit.
Then the mileage is displayed.
How to Change The Display For Odo/trip Meter
Operating the odo/trip meter switch allows switching the mode in the following order.
The odo/trip meter display switching and trip display resetting
can be identified by the time from pressing the odo/trip meter
switch (1) to releasing it.
When resetting with “trip A” displayed, only “trip A” display is
reset. (The same way for “trip B”.)

Target Setting
CAUTION:
Perform this operation in a horizontal position where there is a clear view for 5 m (16.4 ft) forward
and 3 m (9.84 ft) wide.
Place the target at a well-lighted location. (Poor lighting may make it hard to adjust.)
The target may not be detected when there is a light source within 1.5 m (4.92 ft) from either side
and within 1 m (3.28 ft) upward/downward from the target.
Make sure location of the sun. (Sunlight should not shine directly on front of the vehicle.)
The target may not be detected when there is the same pattern of black and white as the target
when the pattern is within 1 m (3.28 ft) from either side and upward/downward position from the
target. (It is desirable that the vehicle is positioned on the opposite side of a single-color wall.)
1. Mark a point at the center of lateral surface of each wheels (“A”,
“B”, “C” and “D”).
NOTE:
Dangle a string with a cone from the fender so as to pass
through the center of wheel, and then mark a point at the center
of lateral surface of wheels.
2. Draw a line passing through points “A” and “B” on the left side of
vehicle (line “LH”).
NOTE:
Approximately 4 m (13.12 ft) or more from the forward end of
vehicle.
3. Mark points on the line “LH”, at the positions 3850 mm (151.57 in) from the point “A” (“E”).
4. Draw a line passing through the points “C” and “D” on the right side of vehicle as with the step 2 (line
“RH”).
NOTE:
Approximately 4 m (13.12 ft) or more from the forward end of vehicle.
5. Mark points on the line “RH”, at the positions 3850 mm (151.57 in) from the point “C” (“F”).
6. Draw a line passing through the points “E” and “F” (line “FW”).

7. Mark point at the center of the point “E” and “F”, on the line
“FW”.
CAUTION:
Make sure that “E” through “X” is equal to “F” through “X”.
8. Position the center of the right target to the point of “X”.
VEHICLE HEIGHT CHECK
Measure the wheel arch height. And calculate “Dh”.
NOTE:
“Dh” may be calculated as a minus value.
AIMING ADJUSTMENT
Operation Procedure
CAUTION:
Perform the adjustment under unloaded vehicle condition.
LDW indicator is turned off after the removal/installation, and blinks after replacement.
1. With the ignition switch OFF, connect CONSULT-II and CON-
SULT-II CONVERTER to the data link connector, and then turn
ignition switch ON.
2. Start the engine, wait for at least 10 seconds, and touch “START
(NISSAN BASED VHCL)”.
