INSPECTION PROCEDURE
HINT:
Start the inspection from step 1 when using the hand-held tester and start from step 3 when not using the
hand-held tester.
1 READ VALUE OF HAND-HELD TESTER(REAR SPEED 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 there is no difference between the speed value output from the speed sensor displayed
by 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.
NG Go to step 3
OK
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

tion system, the DTC U0123/62 (yaw rate sensor communication trouble) and U0124/95 (G sensor commu-
nication trouble) are output.
