U2287 – Lost Communication with the Steering Angle Sensor.

The ODBII code U2287 indicates that there is a loss of communication between the vehicle’s control module and the steering angle sensor, which may affect the vehicle’s stability control and steering functions.

The severity of ODBII code U2287 is generally considered moderate.

Common Causes For: U2285 Lost Communication with the Steering Angle Sensor.

• Faulty steering angle sensor
• Damaged wiring or connectors
• Poor electrical connections
• Failed steering column control module
• Software issues or calibration errors
• Low battery voltage or power supply issues
• Interference from other electronic components

Common misdiagnosis for U2287 Lost Communication with the Steering Angle Sensor.

• Faulty steering angle sensor
• Wiring issues or damaged connectors
• Faulty steering column module
• Malfunctioning ABS module
• Incorrectly calibrated steering angle sensor
• Power supply issues
• Faulty electronic control unit (ECU)

Common Troubleshooting Steps

When dealing with the OBD-II code U2287, 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, related codes can provide more context for 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, corroded, or pushed back.
• 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.
• **Resistance and Voltage: Check the resistance and voltage output of the sensor according to the manufacturer’s specifications.
• Check Power and Ground: **Power Supply: Verify that the steering angle sensor is receiving the correct voltage from the vehicle’s electrical system.
• **Ground Connection: Ensure that the ground connection for the sensor is solid and free of corrosion.
• Inspect the CAN Bus: **Communication Lines: Since the steering angle sensor communicates over the CAN bus, check for any issues with the CAN wiring. Look for shorts, opens, or interference.
• **Other Modules: Ensure that other modules on the CAN bus are functioning correctly, as a fault in one module can affect communication.
• Check for Software Updates: **ECU Updates: Check if there are any software updates available for the vehicle’s ECU that may address communication issues.
• 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 Technical Service Bulletins (TSBs): Look for any TSBs related to the steering angle sensor or communication issues for your specific vehicle make and model. Manufacturers may have known fixes for common problems.
• Professional Diagnosis: If the issue persists after performing the above steps, consider seeking help from a professional mechanic or dealership, as they may have specialized tools and knowledge to diagnose the problem further.Conclusion By following these troubleshooting steps, you can systematically identify and resolve the issue related to the U2287 code. Always refer to the vehicle’s service manual for specific procedures and specifications related to your vehicle model.
