TROUBLE DIAGNOSIS
Revision: 2006 July 2007 FX35/FX45
Basic InspectionNFS000NI
BRAKE FLUID AMOUNT, LEAKS, AND BRAKE PADS INSPECTION
1. Check fluid level in the brake reservoir tank. If fluid level is low, refill brake fluid.
2. Check brake piping and around ABS actuator and electric unit (control unit) for leaks. If there is leaking or oozing fluid, check the following items.

If ABS actuator and electric unit (control unit) connection is loose, tighten piping to the specified torque
and re-perform the leak inspection to make sure there are no leaks.

If there is damage to the connection flare nut or ABS actuator and electric unit (control unit) screw,
replace the damaged part and re-perform the leak inspection to make sure there are no leaks.

When there is fluid leaking or oozing from a part other than ABS actuator and electric unit (control unit)
connection, if fluid is just oozing out, use a clean cloth to wipe off the oozing fluid and re-check for
leaks. If fluid is still oozing out, replace the damaged part.

When there is fluid leaking or oozing at ABS actuator and electric unit (control unit), if fluid is just oozing
out, use a clean cloth to wipe off oozing fluid and re-check for leaks. If fluid is still oozing out, replace
ABS actuator and electric unit (control unit) body.
CAUTION:
ABS actuator and electric unit (control unit) body can not be disassembled.
3. Check brake pad degree of wear. Refer to BR-19, "
PAD WEAR INSPECTION" in “Front Disc Brake” and
BR-25, "
PAD WEAR INSPECTION" in “Rear Disc Brake”
POWER SYSTEM TERMINAL LOOSENESS AND BATTERY INSPECTION
Make sure battery positive cable, negative cable and ground connection are not loose. If looseness is
detected, tighten the cables. In addition, check the battery voltage to make sure it has not dropped and alter-
nator is normal.
ABS WARNING LAMP, VDC OFF INDICATOR LAMP, SLIP INDICATOR LAMP AND BRAKE
WARNING LAMP INSPECTION
× : ON –: OFF
Note 1:Brake warning lamp will turn on in case of operating parking brake (switch turned on) or of actuating brake fluid level switch
(brake fluid is insufficient).
Note 2:After starting engine, turn OFF.
1. Make sure ABS warning lamp, VDC OFF indicator lamp (when VDC OFF switch is OFF), and SLIP indica- tor lamp turn on approximately 2 second, and brake warning lamp turns on when ignition switch is turned
ON. If they do not, check VDC OFF indicator lamp and then VDC OFF switch. Refer to BRC-52, "
VDC
OFF SWITCH" . Check CAN communications. Refer to “CAN Communication Inspection”. If there are no
errors with VDC OFF switch and CAN communication system, check combination meter. Refer to DI-5,
"COMBINATION METERS" .
2. Make sure ABS warning lamp, VDC OFF indicator lamp, SLIP indicator lamp turn off approximately 2 sec- ond after turn ignition switch ON, and brake warning lamp turns off after engine starts. If lamps do not turn
off, perform self-diagnosis.

Removal and InstallationNFS000O6
REMOVAL
1. Disconnect ABS actuator and electric unit (control unit) connector.
2. Loosen brake tube flare nuts, then remove brake tubes from ABS actuator and electric unit (control unit).
3. Remove LH side fender protector. Refer to EI-24, "
FENDER PROTECTOR" .
4. Remove ABS actuator and electric unit (control unit) mounting nuts.
5. Remove ABS actuator and electric unit (control unit) from vehicle.
CAUTION:
Be careful of the following when removing ABS actuator and electric unit (control unit).

If the part number on the part number label (pasted on actuator upper surface) is the same, ABS
actuator and electric unit (control unit) can not be used on another vehicle.
If it is used on another vehicle, ABS warning lamp, SLIP indicator lamp and VDC OFF indicator
lamp may turn ON or VDC/TCS/ABS may not operate normally.
When replacing ABS actuator and electric unit (control unit), must use new service parts.

Before servicing, disconnect battery cables.

To remove brake tube, use a flare nut torque wrench to prevent flare nuts and brake tube from
being damaged. To install, use a flare nut torque wrench (commercial service tool) and tighten to
the specified torque.

Do not apply excessive impact to actuator, such as dropping it.

Do not remove and install ABS actuator and electric unit (control unit) by holding harness.

FUEL GAUGE
The fuel gauge indicates the approximate fuel level in the fuel tank.

Unified meter and A/C amp. reads a resistor signal from fuel level sensor.
Signal is 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 a fuel level signal to combination meter with communication line.

Combination meter indicates the approximate fuel level according to the fuel level signal.
ODO/TRIP METER

ABS actuator and electric unit (control unit) provides a vehicle speed signal to the unified meter and A/C
amp. with CAN communication.

Unified meter and A/C amp. converts the vehicle speed signal to the 8-pulse signal, and outputs the vehi-
cle speed signal (8-pulse) to combination meter.

Combination meter uses the vehicle speed signal (8-pulse) to calculate the mileage, and displays it.
How to Change The Display For Odo/trip Meter
Switch modes with following procedure.

When trip transfer switch is pressed, trip meter display changes.

If trip reset switch is pressed for 1 second or more while “trip A”
is displayed, only “trip A” is reset.
NOTE:
The record of the odo meter is kept even if the battery cable is dis-
connected. The record of the trip meter is erased when the battery
cable is disconnected.
