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

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Repair or replace malfunctioning components.

4.

CHECK DATA MONITOR

1.

Connect the steering angle sensor connector and ABS actuator and electric unit (control unit) connector.

2.

Check steering angle sensor signal.

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> Adjust neutral position of steering angle sensor.

5.

CHECK FOR BACKLASH

1.

Check for backlash [turn wheel to left then straight then right then straight (approx. 90)].

2.

Check straight position is always similar value.

Is there noticeable backlash?

YES

>> Check sensor is correctly fitted to combination witch.

NO

>> Check sensor output is correct from lock to lock.

CHECK DATA MONITOR

Select “STR ANGLE SIG” in “DATA MONITOR” and check steering angle sensor signal.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Go to diagnosis procedure. Refer to 

BRC-130, "Diagnosis Procedure"

.

Special Repair Requirement

C1145 YAW RATE SENSOR

Description

INFOID:0000000000924877

The yaw rate sensor detects the yaw rate affecting the vehicle, and transmits the data to the ABS actuator and
electric unit (control unit) as an analog voltage signal.

DTC CONFIRMATION PROCEDURE

1.

CHECK SELF-DIAGNOSIS RESULTS

Check the self-diagnosis results.

Is above displayed on the self-diagnosis display?

YES

>> Proceed to diagnosis procedure. Refer to 

BRC-133, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000000924879

CAUTION:

• Driving on high speed banked corners can also indicate yaw rate sensor malfunction.
• If vehicle is on turn-table at entrance to parking garage, or on other moving surface, VDC OFF indica-

tor lamp may illuminate and CONSULT-III self-diagnosis may indicate yaw rate sensor system mal-
function. However, in this case there is no malfunction in yaw rate sensor system. Take vehicle off of
turn-table or other moving surface, and start engine. Results will return to normal. And after doing
spin turns or acceleration turns with VDC function is being off (VDC OFF switch “ON”), too, the
results will return to a normal condition by re-starting vehicle.

INSPECTION PROCEDURE

1.

CHECK INSTALLATION STATE OF YAW RATE SENSOR

Check yaw rate sensor is correctly attached to vehicle. Refer to 

BRC-178, "Exploded View"

.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair or replace malfunctioning parts.

2.

CHECK CONNECTOR

1.

Turn ignition switch OFF.

2.

Disconnect ABS actuator and electric unit (control unit) connector.

3.

Disconnect yaw rate sensor connector.

4.

Check terminal for deformation, disconnection, looseness, and so on. If any malfunction is found, repair or
replace terminal.

5.

Reconnect connectors and then perform the self-diagnosis. Refer to 

BRC-96, "CONSULT-III Function

(ABS)"

.

Is any item indicated on the self-diagnosis display?

YES

>> GO TO 3.

NO

>> Poor connection of connector terminal. Replace or repair connector.
