Calibration (Setting up the zero angle)
The Steering Wheel Angle Sensor of an absolute angle type (CAN type) measures the angle under the standard of the zero angle set. Calibration must be performed in the following cases.
- Replacement of the Steering Wheel Angle Speed Sensor
- Replacement or repair of the Steering column
- Detection of DTC codes (C1260, C1261)
- Replacement of the sensor cluster
- Replacement of HECU
Calibration procedure
Perform wheel alignment and stand the steering wheel in a line within ±5°error.
Scheme 56
- Connect the GDS.(CAN line or OBD connector)
- Turn ignition switch on.
- Press calibration button of the Steering Wheel Angle Sensor.
- HECU calibration procedure is performed. (Calibration records, DTC codes erasure)
- Turn ignition switch off after calibration procedure.
- Confirm success or failure of calibration. Warning lamp must not be lit during driving test (turning left and right). The ESC system will light the ESC OFF/Warning lamp when the system detects a sensor error.
