Calibration (Setting up the zero angle)

Steering Wheel Angle Sensor of a absolute angle type (CAN type) measures the angle under the standard of the zero angle set.

Calibration must be performed as following cases.

1. Replacement of the Steering Wheel Angle Speed Sensor
2. Replacement or repair of the Steering column
3. Detection of DTC codes (C1260, C1261)
4. Replacement of the yaw-rate and G sensor
5. Replacement of HECU

Calibration procedure

Perform wheel alignment and stand the steering wheel in a line within ±5° error.

Scheme 16

1. Connect the GDS. (CAN line or OBD connector)
2. Turn ignition switch on.
3. Press calibration button of the Steering Wheel Angle Sensor.
4. HECU calibration procedure is performed. (Calibration records, DTC codes erasure)
5. Turn ignition switch off after calibration procedure.
6. Confirm success or failure of calibration. Warning lamp must not be lighted when driving test (Turning left and right). ESC lights ESC OFF warning lamp when making an error in comparison with values of other sensors.
