2 INSPECT SPEED SENSOR AND SENSOR ROTOR SERRATIONS
INSPECTION USING OSCILLOSCOPE
(a) Connect the oscilloscope to terminals RR+ - RR- or RL+
- RL- of the skid control ECU.
(b) Drive the vehicle at approximately 19 mph (30 km/h), and
check the signal waveform.
OK:
A waveform as shown in a figure should be output.
HINT:
As the vehicle speed (wheel revolution speed) increases,
a cycle of the waveform narrows and the fluctuation 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 at-
tached to it.
NG Go to step 6
OK

INSPECTION PROCEDURE
HINT:
When U0121/94, U0123/62, U0124/95 or U0126/63 are output together with C1231/31, inspect and
repair the trouble areas indicated by U0121/94, U0123/62, U0124/95 or U0126/63 first.
When the speed sensor or the yaw rate sensor has trouble, DTCs for the steering angle sensor may
be output even when the steering angle sensor is normal. When DTCs for the speed sensor or yaw
rate sensor are output together with other DTCs for the steering angle sensor, inspect and repair the
speed sensor and yaw rate sensor first, and then inspect and repair the steering angle sensor.
Start the inspection from step 1 when using the hand-held tester and start from step 2 when not using
the hand-held tester.
1 READ VALUE OF HAND-HELD TESTER(STEERING ANGLE SENSOR)
(a) Connect the hand-held tester to the DLC3.
(b) Start the engine.
(c) Select the DATA LIST mode on the hand-held tester.
(d) Check that the steering angle value of the steering angle sensor indicated on the hand-held tester,
changes when the steering wheel is turned.
