Overview/CAN Communication System/Diagnosis System.
(d) Start the engine.
(e) Drive the vehicle and turn the steering wheel to the right and left at a speed of 35 km/h (22 mph) and check that no speed sensor or
yaw rate and acceleration sensor DTCs are output See: Brakes and Traction Control/Antilock Brakes / Traction Control
Systems/Testing and Inspection/Reading and Clearing Diagnostic Trouble Codes.
Result:
HINT
- If there is a malfunction in any of the speed sensors or the yaw rate and acceleration sensor, an abnormal value may be output
although the steering angle sensor is normal.
- If speed sensor and yaw rate and acceleration sensor DTCs are output simultaneously, repair these two sensors first and
inspect the steering angle sensor.

Troubleshooting
A -- Continue to next step.
2. INSPECT STEERING ANGLE SENSOR (POWER SOURCE TERMINAL)
(a) Turn the engine switch off.
(b) Remove the steering wheel and the column cover lower.
(c) Make sure that there is no looseness at the locking part and the connecting part of the connector.
(d) Disconnect the steering angle sensor connector.
(e) Measure the voltage according to the value(s) in the table below.
Standard Voltage:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (POWER SOURCE CIRCUIT)
OK -- Continue to next step.
3. INSPECT STEERING ANGLE SENSOR (GROUND TERMINAL)
(a) Turn the engine switch off.
