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).

Note 1: After completing repairs of the shorted sensor circuit, when ignition switch is turned ON, ABS warning lamp turns on. Check that
ABS warning lamp turns off while driving the vehicle at approximately 30 km/h (19 MPH) or more for approximately 1 minute according
to self-diagnosis procedure. In addition, if wheel sensor 2 is displayed for the wheels, check the wheel sensor circuit and also check the

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.

Basic InspectionNFS00037
BRAKE FLUID AMOUNT, LEAKS, AND BRAKE PADS INSPECTION
1. Check fluid level in the brake reservoir tank. If fluid level is low, refill the brake fluid.
2. Check brake tubes or hoses 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 the piping to the specified
torque and re-conduct 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-conduct 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 the 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 the 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 ABS actuator and electric unit (control unit) body.
CAUTION:
ABS actuator and electric unit (control unit) cannot be disassembled.
3. Check brake pad degree of wear. Refer to BR-26, "
PAD WEAR INSPECTION" in “Front Disc Brake” and
BR-39, "
PAD WEAR INSPECTION" in “Rear Disc Brake”.
POWER SYSTEM TERMINAL LOOSENESS AND BATTERY INSPECTION
Make sure the battery positive cable, negative cable and ground connection are not loose. In addition, check
the battery voltage to make sure it has not dropped.
