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
control unit power voltage.
Note 2: When errors are detected in several systems, including the CAN communication system [U1000], troubleshoot the CAN commu-
nication system.

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.

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.

INSPECTION PROCEDURE
1. CHECK SELF-DIAGNOSIS RESULTS
Check self-diagnosis results.
Is the above displayed in the self-diagnosis display item?
YES >> GO TO 2.
NO >> INSPECTION END
2. CHECK CONNECTOR
1. Disconnect ABS actuator and electric unit (control unit) connector E51, check terminal to see if it is
deformed, disconnected, loose, etc., and if there is an error, repair or replace the terminal.
2. Securely reconnect the connector 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 3.
3. CHECK ABS ACTUATOR RELAY OR ABS MOTOR RELAY POWER CIRCUIT
1. Disconnect ABS actuator and electric unit (control unit) connec-
tor E51.
2. For ABS actuator relay, measure the voltage between the con-
nector terminal 1 and ground. For ABS motor relay, measure the
voltage between connector terminal 15 and ground.
OK or NG
OK >> GO TO 4
NG >> Error in the circuit between battery and ABS actuator and electric unit (control unit). Repair the cir-
cuit.
4. CHECK ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) GROUND CIRCUIT
Check continuity between ABS actuator and electric unit (control
unit) connector and ground.
OK or NG
OK >> Replace ABS actuator and electric unit (control unit).
NG >> Open or short in harness. Repair or replace the harness.

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).
