YES

>> GO TO 3.

NO

>> Repair the unified meter and A/C amp. branch line.

3.

CHECK POWER SUPPLY AND GROUND CIRCUIT

Check the power supply and the ground circuit of the unified meter and A/C amp. Refer to 

MWI-49, "UNIFIED

METER AND A/C AMP. : Diagnosis Procedure"

.

Is the inspection result normal?

YES (Present error)>>Replace the unified meter and A/C amp. Refer to 

MWI-158, "Exploded View"

.

YES (Past error)>>Error was detected in the unified meter and A/C amp. branch line.
NO

>> Repair the power supply and the ground circuit.

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-82, "Wiring Dia-

gram -BRAKE CONTROL SYSTEM-"

.

Is the inspection result normal?

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

BRC-105, "Exploded View"

.

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

>> Repair the power supply and the ground circuit.
