■ CAUTION ■ Never check between wheel sensor terminals. 1.CHECK TIRES Check air pressure, wear and size. Refer to Tire. Is the inspection result normal? YES>>GO TO 2.
NO>>Repair or replace error-detected parts.
2.CHECK SENSOR AND SENSOR ROTOR

- Check sensor rotor for damage.
- Check wheel sensor for damage, disconnection, or looseness.

Is the inspection result normal?
YES>>GO TO 3.
NO>>Repair wheel sensor mount or replace sensor rotor. Then perform self-diagnosis for “ABS” with CONSULT-III. Refer to Removal and Installation (GT-R certified NISSAN dealer) (front), Removal and Installation (GT-R certified NISSAN dealer) (rear).
3.CHECK CONNECTOR

1. Turn the ignition switch OFF.
2. Disconnect ABS actuator and electric unit (control unit) harness connector.
3. Disconnect malfunctioning wheel sensor harness connector.
4. Check terminal to see if it is deformed, disconnected, loose, etc.

Is the inspection result normal?
YES>>GO TO 4.
NO>>Repair or replace error-detected parts.
4.CHECK WHEEL SENSOR HARNESS

1. Check the continuity between the ABS actuator and electric unit (control unit) harness connector and wheel sensor harness connector. (Also check continuity when steering wheel is turned right and left and when sensor harness inside the wheel house is moved)

   46 | E27 (Front LH)
   42 | B249 | Rear RH | 4
   37 | Rear LH | 2

2. Check the continuity between the ABS actuator and electric unit (control unit) harness connector.

   ABS actuator and electric unit (control unit) | Continuity
   Connector | Terminal | Connector | Terminal
   E41 | 34, 33 | E41 | 16, 47 | Not existed
   45, 46
   43, 42
   36, 37

Is the inspection result normal?
YES>>GO TO 5.
NO>>Repair or replace error-detected parts.
5.REPLACE WHEEL SENSOR

1. Replace wheel sensor. Exploded View (GT-R certified NISSAN dealer) (front), Exploded View (GT-R certified NISSAN dealer) (rear).
2. Erase self-diagnosis results for “ABS” with CONSULT-III.
3. Turn the ignition switch OFF.
4. Turn the ignition switch ON.
   ■ CAUTION ■
   Never start the engine.
5. Perform self-diagnosis for “ABS” with CONSULT-III.

Is DTC “C1115” detected?
YES>>Replace ABS actuator and electric unit (control unit). Refer to Exploded View (GT-R certified NISSAN dealer).
NO>>INSPECTION END
