(1) For vehicles with AYC, be careful when handling
the pole piece at the tip of the speed sensor
so as not to damage it by striking against other
parts.
(2) For vehicles with AYC, be careful not to damage
the rotors installed to B.J. outer race during
removal and installation of the drive shaft.

7. SPEED SENSOR OUTPUT VOLTAGE
MEASUREMENT ABS>
(1) Lift up the vehicle and release the parking brake.
(2) Disconnect the AYC-ECU harness connector and take
measurements on the harness side connector.
Caution
Insert the probe from the harness side with the double
lock of the connector unlocked. Inserting it to the
terminal side could result in poor contact.
(3) Turn the wheel to be tested at about 1/2 to one
revolution/sec. and check for the output voltage using
a circuit tester (AC mV range) or oscilloscope.

Output voltage:
When circuit tester is used: 70 mV or more
When oscilloscope is used: 200 mVp-p or more
(4) If the output voltage is lower than the above value, it
is probably attributable to the following faults. Check or
replace the speed sensor as necessary.
Excessive clearance between the pole piece and rotor
of the speed sensor
Defective speed sensor
Waveform Check Using Oscilloscope
Check the harness and connector of the speed sensor for
connection. Then, use an oscilloscope to check for output
voltage waveform of each speed sensor as follows.
Start the engine and monitor the sensor by turning the wheel;
for a driving wheel, let it turn by shifting into the 1st gear
and for a driven wheel turn it manually at a constant speed.
NOTE
(1) Waveform may be observed by actually running the
vehicle.
(2) The output voltage is low when the wheel speed remains
low and builds up as the wheel speed increases.

(1) With the part marked with *, first temporarily
tighten it, then ground the vehicle and tighten
it to specification in unloaded condition.
(2) When removing the drive shaft from, and
reinstalling it to, a vehicle with AYC, use care
not to damage the rotor mounted on the BJ outer
race.

PARKING BRAKE – On-vehicle Service36-4
2. LINING RUNNING-IN
Carry out running-in by the following procedure when replacing
the parking brake linings or the rear brake disc rotors, or
when brake performance is insufficient.
Caution
Carry out running-in in a place with good visibility, and
pay careful attention to safety.
(1) Adjust the parking brake stroke to the specified value.
Standard value: 5 – 7 notches
[Operating force of approx. 196 N {20 kgf}]
(2) Hook a spring balance onto the center of the parking
brake lever grip and pull it with a force of 98 – 147 N
{10 – 15 kgf} in a direction perpendicular to the handle.
(3) Drive the vehicle at a constant speed of 35 – 50 km/h
for 100 metres.
(4) Release the parking brake and let the brakes cool for
5 – 10 minutes.
(5) Repeat the procedure in steps (2) to (4) 4 – 5 times.
