c1439 steering angle sensor initialization incomplete
C1439 Steering Angle Sensor Initialization Incomplete
OBD2 Code: C1439
Description: Steering Angle Sensor Initialization Incomplete
Definition: This code indicates that the steering angle sensor has not been properly initialized or calibrated. The steering angle sensor is a critical component of the vehicle’s stability control system, and its initialization is necessary for accurate detection of the steering wheel position.
C1439 – Steering Angle Sensor Initialization Incomplete
Typical Severity: Moderate
Common Causes
C1439 – Steering Angle Sensor Initialization Incomplete
Common Causes:
- Low battery voltage
- Steering angle sensor calibration not performed correctly
- Faulty steering angle sensor
- Issues with the steering system wiring or connections
Common Misdiagnosis
OBD2 Code: C1439
Description: Steering Angle Sensor Initialization Incomplete
Common Misdiagnosis: Replacing the steering angle sensor without performing the proper initialization procedure.
Common Diagnostic Steps
OBD2 Code: C1439
Description: Steering Angle Sensor Initialization Incomplete
Common Diagnostic Steps:
- Verify the steering wheel is centered and the vehicle is on a level surface.
- Check for any other related trouble codes and address them first.
- Inspect the wiring and connectors to the steering angle sensor for damage or corrosion.
- Ensure that the battery voltage is within specification, as low voltage can affect sensor calibration.
- Perform a steering angle sensor calibration using an appropriate scan tool according to manufacturer instructions.
- If calibration fails, consider replacing the steering angle sensor if all other components are functioning correctly.
