Fault code No. 42
Item
Rear wheel ABS (intermittent wheel speed pulses or incorrect
depressurization)
Symptom
• Pulses from the rear wheel sensor are received intermittently
while the vehicle is traveling.
• Rear wheel will not recover from the locking tendency even
though the signal is transmitted from the ABS ECU to reduce the
hydraulic pressure.
Order Item/components and probable cause Check or maintenance job
1 Incorrect installation of the rear wheel
sensor
Check the components for looseness, distortion, and
bends.
Refer to “CHECKING THE REAR WHEEL” on page
4-35.
2 Incorrect rotation of the rear wheel Check that there is no brake disc drag on the wheel and
make sure that it rotates smoothly.
Refer to “CHECKING THE REAR WHEEL” on page
4-35 and “CHECKING THE REAR BRAKE DISC” on
page 4-59.
3 Rear brake dragging Check that the brake fluid pressure is correctly transmit-
ted to the brake caliper when the brake pedal is oper-
ated and that the pressure decreases when the pedal is
released.
Refer to “CHECKING THE REAR BRAKE DISC” on
page 4-59.
4 Defective hydraulic unit assembly If the above items were performed and no malfunctions
were found, replace the hydraulic unit assembly.

are detected in the signal while the vehicle is traveling.)
Order Item/components and probable cause Check or maintenance job
1 Foreign material adhered around the front
wheel sensor
Check the surface of the sensor rotor and wheel sensor
for foreign material, such as metal particles.
Clean the sensor rotor and wheel sensor if necessary.
2 Incorrect installation of the front wheel Check the components for looseness, distortion, and
bends.
Refer to “CHECKING THE FRONT WHEEL” on page
4-24.
3 Defective sensor rotor or incorrect instal-
lation of the rotor
Check the surface of the sensor rotor for damage.
Replace the sensor rotor if there is visible damage.
Refer to “MAINTENANCE OF THE FRONT WHEEL
SENSOR AND SENSOR ROTOR” on page 4-26.
4 Defective front wheel sensor or incorrect
installation of the sensor
Check the wheel sensor for damage and the installed
condition of the sensor. Repair or replace the wheel
sensor if necessary.
Refer to “MAINTENANCE OF THE FRONT WHEEL
