INSPECTION
WHEEL SPEED SENSOR CHECK
Check whether any metallic foreign material has ad hered
to the parts shown in the illustration at the wheel speed
sensor tip, and it so, remove it.
NOTE
The section shown in the illustration can become magnetized because of the magnet built into the whe el
speed sensor, with the result that foreign metallic material
is attached to it.
(2) Measure the resistance between the wheel speed sensor
terminals.
Standard value:
If the internal resistance of the wheel speed sensor is
not within the standard value, replace with a new w heel
speed sensor.
(3) Check the wheel 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 cl amp
part from the body and then bend and pull the cable
near the clamp to check whether or not an intermittent
contact results. Check the connector connection and the
terminal insertion.
WHEEL SPEED SENSOR INSULATION CHECK
(1) Remove all connections from the wheel speed sen sor,
and then measure the resistance between terminals ( 1)
and (2) and the body of the wheel speed sensor.
Standard value: 100
or more
(2) If the wheel speed sensor insulation resistance is outside
the standard value range, replace with a new wheel speed
sensor.
