Anti-Lock Brake System (Equipped Models)
Rear Wheel Rotation Sensor Signal Abnormal
(Service Code 44)
Measure the air gap between the rear wheel rotation sen-
sor and sensor rotor (see Wheel Rotation Sensor Air Gap
Check the rear wheel rotation sensor (see Rear Wheel
Rotation Sensor Inspection).
If both inspections are good, go to next step.
Check that there is iron or other magnetic deposits be-
tween the sensor [A] and sensor rotor [B], and the sensor
rotor slots for obstructions.
Check the installation condition of the sensor for loose-
Check the sensor rotor tip for deformation or damage
(e.g., chipped sensor rotor teeth).
If the sensor rotor in bad condition, remove the any de-
posits. Install the proper part or replace faulty part.
If the all items are good, go to next step.
Recheck the service code indication; erase the service
code, perform the pre-diagnosis inspection 1 and 2, and
retrieve the service code.
If the ABS indicator light (LED) [A] lights, the ABS hy-
draulic unit has trouble. Replace the ABS hydraulic unit.
If the ABS indicator light (LED) does not light, ABS system
is normal (service code is not stored; temporary failure.).
Rear Wheel Rotation Sensor Wiring Inspection
(Service Code 45)
ABS Hydraulic Unit Connector (see ABS Hydraulic Unit
Rear Wheel Rotation Sensor Connector (see Rear
Wheel Rotation Sensor Removal)
Check the wiring continuity of the BK lead and BR/BK
Special Tool - Hand Tester 57001-1394
Wiring Continuity Inspection
ABS Hydraulic Unit
BK Lead Terminal [C]
BR/BK Lead Terminal [D]
If there is not the continuity in the lead, replace or repair
the main harness.
If the wiring is good, go to next step.
