1
CHECK POWER SUPPLY FOR STEERING
ANGLE SENSOR.
1) Turn the ignition switch to OFF.
2) Disconnect the connector from steering
angle sensor.
3) Turn the ignition switch to ON.
4) Measure the voltage between steering
angle sensor and chassis ground.
Connector & terminal
(B231) No. 4 (+) — Chassis ground (–):
Is the voltage 10 — 15 V?
Go to step
2.
Repair the steering
angle sensor
power supply cir-
cuit.
2
CHECK GROUND CIRCUIT OF STEERING
ANGLE SENSOR.
Measure the resistance between steering angle
sensor and chassis ground.
Connector & terminal
(B231) No. 3 — Chassis ground:
Is the resistance less than 10
Ω?
Go to step
3.
Repair ground cir-
cuit in the steering
angle sensor.

CHECK STEERING ANGLE SENSOR.
1) Turn the ignition switch to OFF.
2) Connect all connectors.
3) Clear the memory. <Ref. to VDC(diag)-27,
Clear Memory Mode.>
4) Perform the Inspection Mode. <Ref. to
VDC(diag)-26, Inspection Mode.>
5) Read the DTC.
Is the same DTC displayed?
Go to step
4.
Go to step

CHECK VDCCM&H/U.
1) Turn the ignition switch to OFF.
2) Replace the steering angle sensor. <Ref. to
VDC-22, Steering Angle Sensor.>
3) Clear the memory. <Ref. to VDC(diag)-27,
Clear Memory Mode.>
4) Perform the Inspection Mode. <Ref. to
VDC(diag)-26, Inspection Mode.>
5) Read the DTC.
Is the same DTC displayed?
Replace the
VDCCM only.

CHECK OTHER DTC DETECTION.
Is any other DTC displayed?
Perform the diag-
nosis according to
DTC. <Ref. to
VDC(diag)-48, List
of Diagnostic Trou-
ble Code (DTC).>
Temporary poor
contact occurs.
