U0130 Lost Communication With Steering Effort Control Module

The OBD2 code U0130 indicates that there is a loss of communication between the vehicle's control module and the steering effort control module, which can affect the steering system's performance

Definition

The OBD2 code U0130 indicates that there is a loss of communication between the vehicle's control module and the steering effort control module, which can affect the steering system's performance

Common causes

  • Faulty steering effort control module
  • Damaged wiring or connectors
  • Corroded connectors
  • Poor ground connection
  • Faulty power supply to the module
  • Software issues or programming errors
  • Intermittent electrical issues
  • Malfunctioning vehicle control modules

Common misdiagnoses

  • Faulty steering angle sensor
  • Defective power steering pump
  • Malfunctioning electronic control unit (ECU)
  • Wiring issues or short circuits
  • Bad ground connections
  • Faulty steering column assembly
  • Issues with the vehicle's battery or charging system
  • Problems with the anti-lock braking system (ABS) module

Troubleshooting steps

  1. 1. Check for Other Codes

    Use an OBD-II scanner to check for any additional trouble codes. Other codes may provide more context or indicate related issues

  2. 2. Inspect Wiring and Connectors

    Visual Inspection: Check the wiring harness and connectors associated with the steering effort control module for any signs of damage, corrosion, or loose connections

  3. 3. Connector Pins

    Ensure that the pins in the connectors are not bent, corroded, or pushed back

  4. 4. Check Power and Ground

    Verify that the steering effort control module is receiving the correct power supply and ground. Use a multimeter to check voltage and continuity

  5. 5. Test the Steering Effort Control Module

    If possible, test the steering effort control module itself. This may involve bench testing or swapping with a known good module if available

  6. 6. Inspect the CAN Bus

    The communication between modules often occurs over the Controller Area Network (CAN) bus. Check for

  7. 7. Shorts or Opens

    Inspect the CAN bus wiring for shorts to ground or power, or for open circuits

  8. 8. Termination Resistors

    Ensure that the CAN bus has the correct termination resistors in place

  9. 9. Check for Interference

    Look for any aftermarket devices or modifications that may interfere with the vehicle's communication network

  10. 10. Perform a Network Scan

    Use a professional-grade scan tool to perform a network scan. This can help identify communication issues between modules

  11. 11. Clear Codes and Test Drive

    After performing the above checks and repairs, clear the trouble codes and take the vehicle for a test drive to see if the code returns

  12. 12. Consult Technical Service Bulletins (TSBs)

    Check for any TSBs related to the U0130 code for your specific vehicle make and model. Manufacturers may have specific fixes or updates

  13. 13. Seek Professional Help

    If the issue persists after performing these steps, it may be necessary to consult a professional mechanic or dealership for further diagnosis.Conclusion Troubleshooting the U0130 code involves a systematic approach to check for communication issues, inspect wiring and connections, and ensure that the steering effort control module is functioning correctly. Always refer to the vehicle's service manual for specific procedures and specifications
