INSPECTION PROCEDURE
HINT:
Start the inspection from step 1 if you are using the hand±held tester and\
start from step 2 if you are not using
the hand±held tester.
1READ VALUE OF HAND±HELD TESTER(REAR SPEED SENSOR)
(a)Select the item ºWHEEL SPEED RL (RR)º in the DATA LIST and read the value displayed on the hand± held tester.
(b)Check that there is no difference between the speed value output from the speed sensor displayed on the hand±held tester and the speed value displayed on the speedometer when driving the vehicle.
OK: There is almost no difference in the displayed speed value.
HINT:
There is tolerance of
10 % in the speedometer indication.
OKGo to step 5

2INSPECT REAR SPEED SENSOR
(a)Disconnect the skid control sensor connector.
(b)Measure resistance between terminals 1 and 2 of the skid control sensor connector.
OK: Resistance: 2.2 k or less
(c)Measure resistance between each of terminals 1 and 2 of
the skid control sensor connector and body ground.
OK: Resistance: 1 M  or higher
Skid control Sensor Sub±Wire Harness:
(a)Disconnect the sub±wire harness connector from floor wire harness.
(b)Make sure that there is no looseness at the connector lock part and connecting part of the connector.
(c)Measure resistance between terminal 1 of the connector 1 and terminal 2 of the connector 2.
OK: 1  or lower
(d)Measure resistance between terminal 2 of the connector
1 and terminal 1 of the connector 2.
OK: 1  or lower
(e)Measure resistance between terminals 1 and 2 of the speed sensor connector 1 and body ground.
OK: 10 M  or higher
NOTICE:

4INSPECT SENSOR AND SENSOR ROTOR SERRATIONS
(REFERENCE) INSPECTION USING OSCILLOSCOPE
(a)Connect the oscilloscope to the terminals RR+ ± RR± and RL+ ± RL± of the skid control ECU.
(b)Drive the vehicle at about 30 km/h (19 mph), and check the signal waveform.
HINT:

As the vehicle speed (wheel revolution speed) increases,
a cycle of the waveform becomes shorter and the fluctua-
tion in the output voltage becomes greater.

When noise is identified in the waveform on the oscillo-
scope, error signals are generated due to the speed sen-
sor rotor's scratches, looseness or foreign matter depos-
ited on it.

DTC C0200/31 RIGHT FRONT SPEED SENSOR
DTC C0205/32 LEFT FRONT SPEED SENSOR
DTC C1330/35 RIGHT FRONT SPEED SENSOR CIRCUIT
DTC C1331/36 LEFT FRONT SPEED SENSOR CIRCUIT
CIRCUIT DESCRIPTION
The speed sensor detects wheel speed and transmits the ap-
propriate signals to the ECU. These signals are used for control
of the ABS control system. Each of the front and rear rotors has
48 serrations.
When the rotors rotate, the magnetic field generated by the per-
manent magnet in the speed sensor induces an AC voltage.
Since the frequency of this AC voltage changes in direct propor-
tion to the speed of the rotor, the frequency is used by the ECU
to detect the speed of each wheel.
