Definition

The OBD2 code B2368 indicates that there is a malfunction in the steering column switch circuit, specifically that the signal from the switch is outside the expected range, which may affect functions like turn signals or other steering-related controls

Common causes

  • Faulty steering column switch
  • Damaged wiring or connectors
  • Poor electrical connections
  • Malfunctioning body control module (BCM)
  • Corroded terminals
  • Short circuit in the wiring harness
  • Software issues in the vehicle's control modules
  • Incorrectly installed or aftermarket steering components

Common misdiagnoses

  • Faulty steering column switch
  • Wiring issues or shorts in the steering column circuit
  • Malfunctioning body control module (BCM)
  • Incorrectly calibrated steering angle sensor
  • Issues with the power steering system
  • Faulty ignition switch
  • Problems with the vehicle's CAN bus communication
  • Software glitches in the vehicle's control modules

Troubleshooting steps

  1. 1. Check for Additional Codes

    Use an OBD-II scanner to check for any other related trouble codes. Sometimes, multiple codes can provide more context for the issue

  2. 2. Inspect the Steering Column Switch

    Visual Inspection: Check the steering column switch for any visible damage, wear, or corrosion

  3. 3. Connections

    Ensure that all electrical connectors related to the steering column switch are secure and free of corrosion or dirt

  4. 4. Test the Steering Column Switch

    Multimeter Testing: Use a multimeter to test the continuity and resistance of the steering column switch. Compare the readings to the specifications in the vehicle’s service manual

  5. 5. Functionality Check

    Manually operate the switch to see if it functions correctly. Look for any intermittent issues

  6. 6. Inspect Wiring and Connectors

    Wiring Inspection: Check the wiring harness for any signs of damage, fraying, or shorts. Pay special attention to areas where the wiring may be pinched or exposed

  7. 7. Connector Integrity

    Ensure that all connectors are clean and properly seated. Look for bent pins or other issues

  8. 8. Check for Ground Issues

    Ensure that the ground connections related to the steering column switch are secure and free of corrosion. Poor grounding can lead to erratic behavior

  9. 9. Scan for Software Updates

    Check if there are any software updates available for the vehicle’s ECU. Sometimes, manufacturers release updates that can resolve specific issues

  10. 10. Inspect Related Components

    Check other components that may be related to the steering column switch, such as the steering angle sensor or the airbag system, as they can sometimes affect the operation of the switch

  11. 11. 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

  12. 12. Seek Professional Help

    If you are unable to resolve the issue after following these steps, it may be best to consult a professional mechanic or technician who has experience with your specific vehicle make and model. By following these troubleshooting steps, you should be able to identify the cause of the B2368 code and take appropriate action to resolve it
