5. WHEEL SENSOR HARNESS INSPECTION
1. Turn off the ignition switch and disconnect the wheel sensor
connector E42 (FR - LH) or E27 (FR - RH) or T5 (RR - RH, LH)
and ABS control unit connector E51.
2. Check the continuity between terminals. (Also check the conti-
nuity when the steering wheel is turned right and left and when
the sensor harness inside the wheel well is moved.)
OK or NG
OK >> GO TO 6.
NG >> Repair harness and connector between control unit and wheel sensor.
6. WHEEL SENSOR POWER CIRCUIT INSPECTION
1. Connect the wheel sensor connector E42 (FR - LH) or E27 (FR -
RH) or T5 (RR - RH, LH) and ABS control unit connector E51.
2. Turn on the ignition switch and check the voltage between the
power terminal and the ground.
OK or NG
OK >> Replace wheel sensor.
NG >> Replace the control unit.
