ABS <4WD> -
Wheel Speed Sensor
35B-35
(1) Measure the resistance between the wheel speed sensor
terminals.
Standard value: 1.0 - 1.5 k
W
If the internal wheel speed sensor resistance is outside
the standard value range, replace the wheel speed sensor
with a new one.
(2) Check for open circuits in the wheel speed sensor cable.
If a problem is found, replace the cable with a new one.
NOTE
When carrying out open circuit checks, remove the cable
clamps from the vehicle, and flex the cable near the clamp
locations to see if there are any transient open circuits.
Also check the connection of the connector an d that the
terminals are inserted correctly.
WHEEL SPEED SENSOR INSULATION CHECK
(1) After removing the wheel speed sensor, measure the
insulation resistance between terminals (1) and (2) and
the wheel speed sensor body.
Standard value: 10 0 k
W
or more
(2) If the wheel speed sensor insulation resistance is outside
the standard value range, replace the sensor with a new
one.
ABS ROTOR CHECK
Check that none of the ABS rotor teeth are chipped, broken
or bent. If any damage is found, replace the ABS rotor with
a new one.
