DTC C1439/66: Steering Angle Sensor Initialization Incomplete; DTC C1445/66: Vehicle Driven with Steering Angle Sensor not Initialized [10/2013 - ]: Procedure

1. Clear the DTCs. Refer to DTC CHECK / CLEAR [10/2013 - ] .
2. Turn the power switch off.
3. Turn the power switch on (IG) again and check that no CAN communication system DTCs are output. Refer to DIAGNOSIS SYSTEM [10/2013 - ] .
4. Drive the vehicle and turn the steering wheel to the right and left at a speed of 35 km/h (22 mph) and check that no speed sensor, yaw rate and acceleration sensor and steering angle sensor DTCs are output. Refer to DTC CHECK / CLEAR [10/2013 - ] .

   Result

   Result	Proceed to
   DTCs (C1439/66 and/or C1445/66) are output	A
   CAN communication system DTC is output	B
   Speed sensor, yaw rate and acceleration sensor and/or steering angle sensor DTC is output	C
   DTCs (C1439/66 and C1445/66) are not output	D

   HINT: 

   • When DTCs indicating CAN communication system malfunctions are output, repair the CAN communication system before repairing each corresponding sensor.
   • If there is a malfunction in the speed sensor or the yaw rate and acceleration sensor, an abnormal value may be output although the steering angle sensor is normal.
   • If the speed sensor and the yaw rate and acceleration sensor DTCs are output simultaneously, repair the sensors and inspect the steering angle sensor.
   • 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 source voltage drops.

A: Go to next step 

1. Drive the vehicle straight ahead at 35 km/h (22 mph) or more for at least 5 seconds.
2. Check that the steering wheel is centered correctly while driving straight ahead.

   HINT: 

   If the 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.

OK: Go to next step 

1. Turn the power switch off.
2. Clear the DTCs. Refer to DTC CHECK / CLEAR [10/2013 - ] .
3. Turn the power switch on (READY).
4. Drive the vehicle and turn the steering wheel to the right and left at the speed of 35 km/h (22 mph) or more.
5. Check if the same DTC is recorded. Refer to DTC CHECK / CLEAR [10/2013 - ] .

   Result

   Result	Proceed to
   DTCs (C1439/66 and C1445/66) are not output	A
   Yaw rate and acceleration sensor and/or steering angle sensor DTC is output	B

   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 source voltage drops.
