REMOVAL

Caution

Be careful when handling the pole piece at the tip of the
speed sensor and the toothed edge of the rotor so as not
to damage them by striking against other parts:

Проверка

SPEED SENSOR

(1) Check whether any metallic foreign material has adhered
to the pole piece at the speed sensor tip, and, if so,
remove it;

Also check whether the pole piece is damaged, and, if so
replace it with a new one
NOTE

The pole piece can become magnetized because of the
magnet built into the speed sensor, so that metallic
foreign material easily adheres to it.Moreover;thepole
piece may not be able to sense correctly the wheel
rotation speed if it is damaged:

(2) Measure the resistance between the speed sensor
terminals_

Standard value:

Front: 1.17 _ 1.35 kQ

Rear: 1.3 -1.5 ko

If the internal resistance ofthespeed sensor is not within
the standard value, replace it with a new speed sensor:

(3) Remove all connections from the speed sensor; and then
measure the resistance between terminals (1) and (2) and
the body of the speed sensor:

Standard value: 100 kS or more

(4) If the speed sensor insulation resistance is outside the
standard value range, replace with a new speed sensor:

(5) Check the speed sensor cable for breakage, damage or
disconnection; replace with a new one if a problem is
found:

NOTE

When checking for cable damage, remove the cable
clamp part from the body and then bend and pull the
cable neartheclamp to check whether or not temporary
disconnection occurs
