LASER BEAM AIMING ADJUSTMENT
Revision: 2004 November 2004 FX35/FX45
LASER BEAM AIMING ADJUSTMENTPFP:00026
OutlineAKS006YI
Adjust the laser beam aiming every time the ICC sensor is removed or installed.
CAUTION:

Place the vehicle on the level ground when the laser beam aiming adjustment is operated.

Follow the CONSULT-II when adjusting the Laser beam aiming (Laser beam aiming adjustment
cannot be operated without CONSULT-II).
PreparationAKS006YJ

Keep all tires inflated to correct pressures. Adjust the tire pressure to the specified pressure value.

See that there is no-load in vehicle other than the driver (or equivalent weight placed in driver's position).
Coolant, engine oil filled up to correct level and full fuel tank.

Shift the gear into “P” position and release the parking brake.

Clean the sensor with a soft cloth.
Outline of Adjustment ProcedureAKS006YK
1. Set up the ICC target board [KV99110100 (J-45718)].
2. Adjust the sensor following the procedure on CONSULT-II (Turn manually the screw for up-down position
adjustment. ICC sensor automatically adjust the right-left position.).
Setting the ICC Target BoardAKS006YL
Accurate ICC target board setting is required for the laser beam aiming adjustment.
CAUTION:
ICC system does not function normally if laser beam aiming is not accurate.
ADJUSTING HEIGHT OF THE TARGET
1. Attach a triangle scale as shown in the right figure.

COMBINATION METERS
Revision: 2004 November 2004 FX35/FX45
WATER TEMPERATURE GAUGE
The water temperature gauge indicates the engine coolant temperature.
ECM provides a water temperature signal to unified meter and A/C amp. with CAN communication line. Uni-
fied meter and A/C amp. provides a water temperature signal to combination meter for water temperature
gauge with communication line between unified meter and A/C amp. and combination meter.
TACHOMETER
The tachometer indicates engine speed in revolutions per minute (rpm).
ECM provides an engine speed signal to unified meter and A/C amp. with CAN communication line. Unified
meter and A/C amp. provides an engine speed signal to combination meter for tachometer with communica-
tion line between unified meter and A/C amp. and combination meter.
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 36

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 28 for the fuel gauge.
Unified meter and A/C amp. provides an fuel level signal to combination meter for fuel gauge with communica-
tion line between unified meter and A/C amp. and combination meter.
SPEEDOMETER
ABS actuator and electric unit (control unit) provides a vehicle speed signal to the unified meter and A/C amp.
with CAN communication line. After unified meter and A/C amp. received the vehicle speed signal, it changes
the signal to 8 pulse signal and provides the 8 pulse signal to the combination meter for the speedometer.

The following symptoms do not indicate a malfunction.
FUEL GAUGE

Depending on vehicle position or driving circumstance, the fuel in the tank flows and the pointer may fluc-
tuate.

If the vehicle is fueled with the ignition switch ON, the pointer will move slowly.
1. CHECK UNIFIED METER AND A/C AMP. INPUT SIGNAL
1. Select “METER A/C AMP” on CONSULT-II.
2. Using “FUEL METER” on “DATA MONIOR”, compare the value
of “DATA MONITOR” with fuel gauge pointer of combination
meter.

connector M56 terminal 28 (W/B) and fuel level sensor unit (sub)
harness connector B40 terminal 1 (LG).
3. Check continuity between unified meter and A/C amp. harness
connector M56 terminal 28 (W/B) and ground.
OK or NG
OK >> GO TO 4.
NG >> Repair harness or connector.

Fuel Gauge Pointer Fluctuates, Indicator Wrong Value or VariesAKS005N3
1. CHECK FUEL GAUGE FLUCTUATION
Test drive vehicle to see if gauge fluctuates only during driving or before or after stopping.
Does the indication value vary only during driving or before or after stopping?
YES >> The pointer fluctuation may be caused by fuel level change in the fuel tank. Condition is normal.
NO >> Ask the customer about the situation when the symptom occurs in detail, and perform the trouble
diagnosis. 14 (PU) - Ground:
