A -- Continue to next step.

2. CHECK STEERING ANGLE SENSOR ZERO POINT CALIBRATION

(a) Drive the vehicle straight ahead at 35 km/h (22 mph) or more for at least 5 seconds.

(b) Check that the steering wheel is centered correctly while driving straight ahead.

HINT

If front wheel alignment and steering position are adjusted as a result of an off-centered position of the steering wheel, acquire

yaw rate and acceleration sensor zero point again after the adjustments are completed.

OK:

The steering wheel is centered correctly

NG -- ADJUST FRONT WHEEL ALIGNMENT OR STEERING POSITION

OK -- Continue to next step.

3. RECONFIRM DTC

(a) Turn the ignition switch off.

(b) Clear the DTCs See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Testing and Inspection/Reading and

Clearing Diagnostic Trouble Codes/DTC Check / Clear (from 12/2010).

(c) Start the engine.

(d) Drive the vehicle and turn the steering wheel to the right and left at the speed of 35 km/h (22 mph) or more.

(e) Check if the same DTC is output See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Testing and

Inspection/Reading and Clearing Diagnostic Trouble Codes/DTC Check / Clear (from 12/2010).

Result:

HINT

* If the same DTC C1439/66 and/or C1445/66 is not output again, the DTC may have been stored due to a temporary loss of the

steering angle zero calibration, such as when the power voltage drops.

* If troubleshooting has been carried out according to Problem Symptoms Table, refer back to the table and proceed to the next

step See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Testing and Inspection/Symptom Related

Diagnostic Procedures/Vehicle Stability Control System/Problem Symptoms Table (from 12/2010).

Steering Angle Sensor Zero Point Malfunction - Vehicle Stability Control System (to 12/2010)

BRAKE CONTROL: VEHICLE STABILITY CONTROL SYSTEM: C1290/66: Steering Angle Sensor Zero Point Malfunction

C1290/66 - Steering Angle Sensor Zero Point Malfunction

DESCRIPTION

The skid control ECU acquires steering angle sensor zero point every time the ignition switch is turned to the ON position and the vehicle is driven

at 35 km/h (22 mph) or more for approximately 5 seconds. The ECU also stores the previous zero point.

If front wheel alignment or steering wheel position is adjusted without disconnecting the negative battery terminal, or if yaw rate and acceleration
