YES

>> Proceed to

BRC-150, "Diagnosis Procedure"

.

NO-1

>> To check malfunction symptom before repair: Refer to

GI-44, "Intermittent Incident"

.

NO-2

>> Confirmation after repair: INSPECTION END

Diagnosis Procedure

INFOID:0000000010723692

1.

CHECK CONNECTOR

1.

Turn the ignition switch OFF.

2.

Check the ABS actuator and electric unit (control unit) harness connector for disconnection or looseness.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair or replace error-detected parts, securely lock the connector, and GO TO 2.

2.

PERFORM SELF-DIAGNOSIS

Perform self-diagnosis for “ABS” again.

3.

CHECK STEERING ANGLE SENSOR POWER SUPPLY

1.

Turn the ignition switch OFF.

2.

Disconnect the steering angle sensor harness connector.

3.

Check the voltage between steering angle sensor harness connector and ground.

4.

Turn the ignition switch ON.

CAUTION:

Never start engine.

5.

Check the voltage between steering angle sensor harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 6.

NO (With stop / start system)>>GO TO 4.
NO (Without stop / start system)>>GO TO 5.

4.

CHECK STEERING ANGLE SENSOR POWER SUOOLY CIRCUIT (WITH STOP / START SYSTEM)

1.

Turn the ignition switch OFF.

2.

Check the 10A fuse (#54).

3.

Check the continuity and short circuit between steering angle sensor harness connector terminal (4) and
10A fuse (#54).

Is the inspection result normal?

YES

>> Perform trouble diagnosis for ignition power supply.

NO

>> Repair or replace error-detected parts.

5.

CHECK STEERING ANGLE SENSOR POWER SUOOLY CIRCUIT (WITHOUT STOP / START SYSTEM)

1.

Turn the ignition switch OFF.

2.

Check the 10A fuse (#30).

3.

Check the continuity and short circuit between steering angle sensor harness connector terminal (4) and
10A fuse (#30).

Is the inspection result normal?

YES

>> Perform trouble diagnosis for ignition power supply.

NO

>> Repair or replace error-detected parts.

6.

CHECK STEERING ANGLE SENSOR GROUND CIRCUIT

1.

Turn the ignition switch OFF.

2.

Check continuity between steering angle sensor harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 7.

NO

>> Repair or replace error-detected parts.

7.

CHECK TERMINAL

Check steering angle sensor pin terminals for damage or loose connection with harness connector.
