3.CHECK SENSOR AND SENSOR ROTOR
lCheck sensor rotor for damage.
lCheck wheel sensor for damage, disconnection or looseness.
OK or NG
OK >> GO TO 4.
NG >> Repair or replace the malfunctioning component.
4.CHECK CONNECTOR
1. Turn ignition switch OFF and disconnect ABS actuator and electric unit (control unit) connector E63 and
malfunctioning wheel sensor connector E66 (FR - LH), E77 (FR - RH), C10 (RR - LH) or C11 (RR - RH).
Check terminal to see if it is deformed, disconnected, loose, etc., and repair or replace it if any malfunction
condition is found.
2. Reconnect connectors and check that interference with other parts has not cut wheel sensor cables, drive
vehicle at 30 km/h (19 MPH) or more for approximately 1minute, and perform self-diagnosis.
OK or NG
OK >> Connector terminal contact is loose, damaged, open or shorted.
NG >> GO TO 5.
5.CHECK WHEEL SENSOR HARNESS
1. Turn ignition switch OFF and disconnect wheel sensor connec-
tor E66 (FR - LH), E77 (FR - RH), C10 (RR - LH) or C11 (RR -
RH) and ABS actuator and electric unit (control unit) connector
E63.
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.)
OK or NG
OK >> GO TO 6.
NG >> Repair or replace harness and connector that have malfunction.
