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 STEERING SENSOR
(a)Select the DATALIST mode on the hand±held tester.
(b)Check that the steering wheel turning angle value of the steering angle position sensor displayed on the hand±held tester is changing when turning the steering wheel.
OK:
Steering wheel turning angle value is changing.
OKGo to step 4

3 CHECK HARNESS AND CONNECTOR(STEERING SENSOR CIRCUIT ± SKID CONTROL ECU)
(a) Check for an open or short circuit in harness and connector between each term\
inal SS1, SS2, YIGA
and YGND of the skid control ECU and steering angle sensor (See page 01±32).
NG REPAIR OR REPLACE HARNESS ORCONNECTOR
OK
4CALIBRATE STEERING ANGLE SENSOR(See page 05±756)

DTC C0371/55 OPEN OR SHORT CIRCUIT IN YAW RATE
SENSOR CIRCUIT
CIRCUIT DESCRIPTION
DTC No.DTC Detecting ConditionTrouble Area
C0371/55
Detection of any of conditions from 1 through 4:
1. The voltage of sensor signal is out of range.
2. The offset value of sensor signal is outside the plausible
range.
3. Sensor signal changes rapidly under normal driving.
4. Yaw rate sensor value is considerably different from the
reference value of yaw rate during cornering.

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 YAWRATE SENSOR
(a)Remove the 2 bolts and yaw rate sensor with connector
still connected.
(b)Connect the hand±held tester to the DLC3.
(c)Turn the ignition switch and hand±held tester main switch ON.
(d)Select the DATALIST mode on the hand±held tester.
(e)Check the yaw rate value 0
5 deg/s.
(f)Check that the yaw rate value of the yaw rate sensor dis- played on the hand±held tester is changing: Place the
yaw rate sensor vertically to the ground and turn the sen-
sor pivoted on its center.
OK:
Yaw rate value is changing.
