Second generation VI (2009–2026) / Hyundai Equus VI 2009-2026 Service Manual / Brake System / ESP(Electronic Stability Program) System / Steering Angle Sensor Description and Operation
| Description |
Steering Wheel Angle Sensor detects rotating direction of the
vehicle. Rotating direction detected by the sensor is communicated with
HECU as CAN signal involving information about the angle through CAN
communication line.
HECU detects speed of the steering wheel handling and the
angle with this CAN signal. HECU also uses this signal as the input
signal to control anti-roll.

Circuit Diagram
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.
| - |
Replacement of the Steering Wheel Angle Sensor |
| - |
Replacement or repair of the Steering column |
| - |
Detection of DTC codes (C1260, C1261) |
| - |
Replacement of the sensor cluster |
| - |
Replacement of HECU |
