Self-diagnosisNFS000HG
OPERATION PROCEDURE
1. Before performing the self-diagnosis, start engine and drive vehicle at 30 km/h (19 MPH) or more for
approximately 1 minute.
HOW TO ERASE SELF-DIAGNOSIS RESULTS
1. After erasing DTC memory, start engine and drive vehicle at 30 km/h (19 MPH) or more for approximately
1 minute as the final inspection, and make sure that the ABS warning lamp, TCS OFF indicator lamp,
SLIP indicator lamp and brake warning lamp turn OFF.
CAUTION:
If memory cannot be erased, perform applicably diagnosis.
When the wheel sensor malfunctions, after inspecting the wheel sensor system, the ABS warning lamp,
TCS OFF indicator lamp, SLIP indicator lamp and brake warning lamp will not turn OFF even when the
system is normal unless the vehicle is driving at approximately 30 km/h (19 MPH) or more for approxi-
mately 1 minute.
Brake warning lamp will turn ON in case of parking brake operation (when switch is ON) or of brake
fluid level switch operation (when brake fluid is insufficient).

Active TestNFS000IO
CAUTION:
Do not perform active test while driving.
Make sure to completely bleed air from the brake system.
The ABS and brake warning lamps turn on during the active test.
NOTE:
When the active test is conducted while depressing the pedal, the pedal depression amount will change,
but this is normal.
Approximately 10 seconds after the operation is begun, “TEST STOP” will be displayed.
TEST ITEM
Solenoid valve
CAUTION:
The example shown is for the front right wheel. The procedure for the other wheels is the same as
given below.
For ABS solenoid valve, touch “UP”, “KEEP”, and “DOWN”.Then use screen monitor to check that solenoid
valve operates as shown in the table below.
*: ON for 1 to 2 seconds after the touch, and then OFF
ABS Motor
Touch “ON”, “OFF” on the display screen and make sure the ABS motor relay is operating as shown in the
table below.
Correct and Quick DiagnosisNFS00036
DIAGNOSIS PRECAUTIONS
Before performing the trouble diagnosis, always read the general information (GI) to confirm the general
precautions. Refer to GI-3, "
General Precautions" .
After completing service, always erase the self-diagnosis results. Refer to BRC-53, "HOW TO ERASE
SELF-DIAGNOSIS RESULTS" .
When inspection of the continuity or voltage between units is performed, check connector terminals for
disconnection, looseness, bend, or collapse. If any non-standard condition is detected, repair or replace
applicable part.
Intermittent errors may be caused by a poor connection in the harness, connector, or terminal. Move har-
nesses, harness connectors, or terminals by hand to make sure all connections are solid and undamaged.
If a circuit tester is used for the check, be careful not to forcibly extend any connector terminal.
TCS/ABS is a system that uses electronic control to perform brake control and engine power control.
Therefore, phenomena like those shown in the following table may occur, but this is because the system is
working normally.

Symptom Symptom description Result
Motor operation noiseThis is the sound of the motor operating inside ABS actuator and electric unit
(control unit), and there may be some low sounds while TCS or ABS is oper-
ating.
Normal
Just after the engine starts, the motor operating noise may be heard. This is
a normal status of the system operation check.

TROUBLE DIAGNOSIS FOR SYSTEMPFP:00000
Wheel Sensor SystemNFS00038
After using the CONSULT-III SELF-DIAG RESULTS to determine the location of the malfunctioning wheel sen-
sor, check all areas to determine the component to be replaced.
CAUTION:
Do not measure the resistance value and also voltage between the sensor terminal with tester etc.,
because the sensor is an active sensor.
Do not expand the terminal of the connector with a/the tester terminal stick, when it does the
inspection with the tester.
INSPECTION PROCEDURE
1. CHECK SELF-DIAGNOSIS RESULTS
Check self-diagnosis results.
Is the above displayed in the self-diagnosis display items?
YES >> GO TO 2.
NO >> INSPECTION END
2. CHECK TIRE
Check air pressure, wear, and size.
Are the 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 the front sensor rotor rubber for damage.
Check the rear sensor rotor for damage.
OK or NG
OK >> GO TO 4.
NG >> Repair wheel sensor mount or replace the sensor rotor.
4. CHECK CONNECTOR
1. Disconnect ABS actuator and electric unit (control unit) connector and malfunctioning wheel sensor con-
nector E42 (FR - LH) or E27 (FR - RH) or T5 (RR - RH, LH). Check the terminal to see if it is deformed,
disconnected, loose, etc., and replace it if any non-standard condition is found.
2. Reconnect connector, drive at a speed of approximately 30 km/h (19 MPH) or more for approximately 1
minute, and then perform self-diagnosis.
Is the result of self-diagnosis normal?
YES >> The connector terminal contact is loose, damaged, open or shorted.
NO >> GO TO 5.
