Definition

The OBD2 code C0587 indicates a malfunction in the left rear solenoid circuit, specifically that the circuit is reading a low voltage or is open, which may affect the operation of the vehicle's stability or traction control systems

Common causes

  • Faulty left rear solenoid
  • Damaged wiring or connectors
  • Short circuit in the solenoid circuit
  • Open circuit in the solenoid circuit
  • Faulty control module
  • Corrosion in electrical connections
  • Grounding issues

Common misdiagnoses

  • Faulty left rear solenoid
  • Wiring issues or shorts in the circuit
  • Faulty control module
  • Incorrectly diagnosed wheel speed sensor issues
  • Problems with the brake system
  • Battery or charging system issues
  • Faulty connectors or terminals
  • Software or calibration errors in the vehicle's control system

Troubleshooting steps

  1. 1. Check for Additional Codes

    Use an OBD-II scanner to check for any other related trouble codes. This can provide more context and help identify if there are multiple issues

  2. 2. Inspect Wiring and Connectors

    Visually inspect the wiring and connectors associated with the left rear solenoid. Look for

  3. 3. Damaged, frayed, or corroded wires

  4. 4. Loose or disconnected connectors

  5. 5. Signs of moisture or dirt that could affect connections

  6. 6. Test the Solenoid

    If accessible, test the left rear solenoid for proper operation. This may involve

  7. 7. Checking the resistance of the solenoid with a multimeter. Compare the reading to the manufacturer's specifications

  8. 8. Applying direct voltage to the solenoid to see if it activates

  9. 9. Check Power and Ground

    Use a multimeter to check for proper voltage at the solenoid connector

  10. 10. With the ignition on, check for battery voltage at the connector

  11. 11. Check for a good ground connection. If the ground is poor, it can cause low voltage readings

  12. 12. Inspect the Control Module

    If the wiring and solenoid are in good condition, the issue may lie with the control module (e.g., ABS module). Check for

  13. 13. Software updates or recalls related to the control module

  14. 14. Any signs of damage or corrosion on the module

  15. 15. Perform a Visual Inspection of Related Components

    Inspect other components in the system that may affect the solenoid operation, such as

  16. 16. Brake lines and fluid levels

  17. 17. Other sensors related to the ABS or traction control systems

  18. 18. Clear Codes and Test Drive

    After performing any repairs or adjustments, clear the trouble codes using the OBD-II scanner and take the vehicle for a test drive to see if the code returns

  19. 19. Consult Repair Manual or Professional Help

    If the issue persists after following the above steps, consult the vehicle's repair manual for specific diagnostic procedures or consider seeking help from a professional mechanic

  20. 20. Consider Environmental Factors

    Sometimes, environmental factors such as extreme temperatures or moisture can affect electrical components. Ensure that the vehicle is in a suitable environment for testing. By following these steps, you should be able to identify the cause of the C0587 code and take appropriate action to resolve the issue
