STEERING ANGLE SENSOR SIGNAL CIRCUIT

Description

INFOID:0000000005528568

• 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:0000000005528569

1.

CHECK CONTINUITY STEERING ANGLE SENSOR SIGNAL CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect camera control unit connector and steering angle sensor connector.

3.

Check continuity between camera control unit harness connector and steering angle sensor harness con-
nector.

4.

Check continuity between camera control unit harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair harness or connector.

2.

CHECK VOLTAGE CAMERA CONTROL UNIT

1.

Connect camera control unit connector.

2.

Turn ignition switch ON.

3.

Check voltage between camera control unit harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Replace camera control unit.

3.

CHECK STEERING ANGLE SENSOR SIGNAL

1.

Turn ignition switch OFF.

2.

Connect steering angle sensor connector.

STEERING SWITCH SIGNAL A CIRCUIT

Description

INFOID:0000000005528570

Transmits the steering switch signal to AV control unit.

Diagnosis Procedure

INFOID:0000000005528571

1.

CHECK STEERING SWITCH SIGNAL A CIRCUIT

1.

Disconnect AV control unit connector and spiral cable connector. 

2.

Check continuity between AV control unit harness connector and spiral cable harness connector.

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-146, "Component Inspection"

.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Replace steering switch.
