INFOID:0000000003841854

1.

CHECK CONNECTOR

1.

Turn the ignition switch OFF.

2.

Disconnect the battery cable from the negative terminal.

3.

Check the terminals and connectors of the steering angle sensor for damage, bend and loose connection
(unit side and connector side).

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair the terminal and connector.

2.

CHECK HARNESS FOR OPEN CIRCUIT

1.

Disconnect the connector of steering angle sensor.

2.

Check the resistance between the steering angle sensor harness connector terminals.

Is the measurement value within the specification?

YES

>> GO TO 3.

NO

>> Repair the steering angle sensor branch line.

3.

CHECK POWER SUPPLY AND GROUND CIRCUIT

Check the power supply and the ground circuit of the steering angle sensor. Refer to 

BRC-136, "Wiring Dia-

gram - BRAKE CONTROL SYSTEM -"

.

Is the inspection result normal?

YES (Present error)>>Replace the steering angle sensor. Refer to 

BRC-157, "Exploded View"

.

YES (Past error)>>Error was detected in the steering angle sensor branch line.
NO

>> Repair the power supply and the ground circuit.

1.

CHECK CONNECTOR

1.

Turn the ignition switch OFF.

2.

Disconnect the battery cable from the negative terminal.

3.

Check the terminals and connectors of the BCM for damage, bend and loose connection (unit side and
connector side).

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair the terminal and connector.

2.

CHECK HARNESS FOR OPEN CIRCUIT

1.

Disconnect the connector of BCM.

2.

Check the resistance between the BCM harness connector terminals.

Is the measurement value within the specification?

YES

>> GO TO 3.

NO

>> Repair the BCM branch line.

3.

CHECK POWER SUPPLY AND GROUND CIRCUIT

Check the power supply and the ground circuit of the BCM. Refer to 

BCS-37, "Diagnosis Procedure"

.

Is the inspection result normal?

YES (Present error)>>Replace the BCM. Refer to 

BCS-78, "Exploded View"

.

YES (Past error)>>Error was detected in the BCM branch line.
NO

>> Repair the power supply and the ground circuit.

Diagnosis Procedure

INFOID:0000000003841856

1.

CHECK CONNECTOR

1.

Turn the ignition switch OFF.

2.

Disconnect the battery cable from the negative terminal.

3.

Check the terminals and connectors of the data link connector for damage, bend and loose connection
(connector side and harness side).

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair the terminal and connector.

2.

CHECK HARNESS FOR OPEN CIRCUIT

Check the resistance between the data link connector terminals.

Is the measurement value within the specification?

YES (Present error)>>Check CAN system type decision again.
YES (Past error)>>Error was detected in the data link connector branch line circuit.
NO

>> Repair the data link connector branch line.
