Basic Inspection

NFS000FI

BRAKE FLUID LEVEL, LEAKS, AND BRAKE PAD

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 leakage or seep-
age is found, check the following items.

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

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

If there is leakage or seepage at any location other than ABS actuator and electric unit (control unit)
connection, wipe away leakage or seepage with clean cloth. Then inspect again and confirm than there
is on leakage.

If there is leakage from ABS actuator and electric unit (control unit), wipe away leakage or seepage with
clean cloth. Then inspect again. If there is leakage or seepage, replace ABS actuator and electric unit
(control unit).

CAUTION:

ABS actuator and electric unit (control unit) body can not be disassembled.

3.

Check the brake disc rotor and pads. Refer to 

BR-26, "Removal and Installation of Brake Pad"

  in “Front

Disc Brake” an

BR-32, "Removal and Installation of Brake Pad"

  in “Rear Disc Brake”.

POWER SYSTEM TERMINAL LOOSENESS AND BATTERY 

Make sure battery positive cable, negative cable and ground connection are not loose. If looseness is
detected, tighten the piping to the specified torquer. In addition, check the battery voltage to make sure it has
not dropped and alternator is normal.

ABS WARNING LAMP AND BRAKE WARNING LAMP

–: 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

TROUBLE DIAGNOSIS FOR SYSTEM

PFP:00000

Wheel Sensor 

NFS000FJ

After using CONSULT-II SELF-DIAG RESULTS to determine position of malfunctioning wheel sensor, check
all areas to determine the component to be replaced.

CAUTION:

Do not measure resistance value and also voltage between sensor terminal with tester etc.,
because sensor is an active sensor.

Do not expand terminal of connector with a tester terminal stick, when it does inspection with
tester.

INSPECTION PROCEDURE

1. 

CHECK SELF-DIAGNOSTIC RESULTS

 With CONSULT-II

1.

Turn ignition switch “ON”. (Do not start engine.)

2.

Select “SELF-DIAG RESULTS” mode for “ABS” with CONSULT-II.

3.

Touch “ERASE”.

4.

Turn ignition switch “OFF” and wait at least 10 seconds.

5.

Check the self-diagnostic results.

Is above displayed in the self-diagnosis display?

YES

>> GO TO 2.

NO

>> INSPECTION END

2. 

CHECK TIRE

Check air pressure, wear, and size.

Are air pressure, wear, and size within the standard values?

YES

>> GO TO 3.

NO

>> Adjust air pressure, or replace tire.

3. 

CHECK SENSOR AND SENSOR ROTOR 

Check the condition of the sensor mount (for looseness, etc.).

Check the surface of front sensor rotor for damage.

Check rear sensor rotor for damage.

OK or NG

OK

>> GO TO 4.

NG

>> Repair sensor mount or replace sensor rotor. Refer to 

BRC-44, "SENSOR ROTOR"

 .

tor E20 (FR - LH), E27 (FR - RH), B202 (RR - LH), B203 (RR -
RH) and ABS actuator and electric unit (control unit) connector
E24.

2.

Check continuity between terminals. (Also check continuity
when steering wheel is turned right and left and when sensor
harness inside wheel well is moved.)

WHEEL SENSORS

PFP:47910

Removal and Installation

NFS000FV

REMOVAL

Be careful of the following.

CAUTION:

As much as possible, avoid rotating wheel sensor when removing it. Pull wheel sensors out with-
out pulling on sensor harness.

Take care to avoid damaging wheel sensor edges or rotor teeth. Remove wheel sensor first before
removing front or rear wheel hub. This is to avoid damage to wheel sensor wiring and loss of sen-
sor function.

INSTALLATION

Be careful of the following. Tighten the mounting bolts and nuts to the specified torque. Refer to 

BRC-43,

"Removal and Installation"

 .

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 figure. When installed, harness must not be twisted.
