U2585 – Lost Communication with the Steering Angle Sensor.

The ODBII code U2585 indicates a loss of communication with the steering angle sensor, which may affect the vehicle’s stability control and steering systems.

The severity of ODBII code U2585 is generally considered moderate.

Common Causes For: U2584 U2584: Vehicle Communication Bus Malfunction

• Faulty steering angle sensor
• Damaged wiring or connectors
• Poor electrical connections
• Malfunctioning power steering control module
• Software issues or calibration errors
• Faulty vehicle control module (VCM)
• Interference from other electronic components

Common misdiagnosis for U2585 Lost Communication with the Steering Angle Sensor.

• Faulty steering angle sensor
• Wiring issues or damaged connectors
• Faulty steering column module
• Malfunctioning electronic stability control (ESC) system
• Issues with the vehicle’s body control module (BCM)
• Problems with the power steering system
• Faulty ABS module
• Software or calibration issues in the vehicle’s control modules

Common Troubleshooting Steps

When dealing with OBD-II code U2585, which indicates “Lost Communication with the Steering Angle Sensor,” there are several common troubleshooting steps you can follow to diagnose and potentially resolve the issue. Here’s a structured approach:

• Check for Other Codes: Use an OBD-II scanner to check for any additional trouble codes. Sometimes, multiple codes can provide more context about the issue.
• Inspect Wiring and Connectors: **Visual Inspection: Check the wiring harness and connectors associated with the steering angle sensor for any signs of damage, corrosion, or loose connections.
• **Connector Pins: Ensure that the pins in the connectors are not bent or corroded.
• Test the Steering Angle Sensor: **Sensor Functionality: If possible, test the steering angle sensor using a multimeter or scan tool to ensure it is functioning correctly. Check for proper voltage and resistance values as specified in the vehicle’s service manual.
• **Calibration: Some vehicles require the steering angle sensor to be calibrated after installation or repair. Check if calibration is necessary.
• Check the CAN Bus Communication: **Network Integrity: Since the steering angle sensor communicates over the CAN bus, check for any issues with the CAN network. Look for short circuits, open circuits, or other communication faults.
• **Scan Tool: Use a professional scan tool to monitor the CAN bus data and see if the steering angle sensor is transmitting data.
• Inspect the Power and Ground Supply: **Power Supply: Verify that the steering angle sensor is receiving the correct voltage. Check the vehicle’s wiring diagrams for the correct voltage specifications.
• **Ground Connection: Ensure that the ground connection for the sensor is solid and free of corrosion.
• Check for Software Updates: **ECU Updates: Sometimes, the issue can be resolved with a software update to the vehicle’s ECU. Check with the manufacturer for any available updates.
• Test the Steering Column and Related Components: **Steering Column Issues: Inspect the steering column for any mechanical issues that could affect the sensor’s operation.
• **Other Sensors: Check other related sensors (like the yaw rate sensor) that may also affect the steering angle sensor’s performance.
• Clear Codes and Test Drive: After performing the above checks and repairs, clear the trouble codes using the OBD-II scanner and take the vehicle for a test drive to see if the code returns.
• Consult a Professional: If the issue persists after performing these steps, it may be necessary to consult a professional mechanic or technician who has experience with your specific vehicle make and model.Conclusion By following these troubleshooting steps, you can systematically identify and resolve the issue related to the U2585 code. Always refer to the vehicle’s service manual for specific details and specifications related to the steering angle sensor and its circuitry.
