STEERING ANGLE SENSOR SIGNAL CIRCUIT

Description

INFOID:0000000003544795

• Steering angle sensor signal 1, 2 detects the turning direction and quantity of the steering and transmits it to

the camera control unit.

• Steering angle sensor signal 3 detects the neutral position of the steering and transmits it to the camera con-

trol unit.

• Camera control unit performs the correction of neutral position with sensor signal 1, 2, 3 and vehicle speed

signal.

Diagnosis Procedure

INFOID:0000000003544796

1.

CHECK CONTINUITY STEERING ANGLE SENSOR SIGNAL CIRCUIT

1.

3.

Check continuity between AV control unit harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair harness or connector.

2.

CHECK SPIRAL CABLE

Check spiral cable. 
Is the inspection result normal?

YES

>> GO TO 3. 

NO

>> Replace spiral cable.

3.

CHECK AV CONTROL UNIT VOLTAGE

1.

Connect AV control unit connector and spiral cable connector.

2.

Turn ignition switch ON.

3.

Check voltage between AV control unit harness connector.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Replace AV control unit.

4.

CHECK STEERING SWITCH

1.

Turn ignition switch OFF.

2.

Check steering switch. Refer to 

AV-248, "Component Inspection"

.

Is the inspection result normal?

YES

>> INSPECTION END
