C1195 ABS Outlet Valve Coil LF Circuit Open

The OBD2 code C1195 indicates that there is an open circuit in the left front (LF) outlet valve coil of the ABS (Anti-lock Braking System), which can affect the operation of the ABS

Definition

The OBD2 code C1195 indicates that there is an open circuit in the left front (LF) outlet valve coil of the ABS (Anti-lock Braking System), which can affect the operation of the ABS

Common causes

  • Open circuit in the ABS outlet valve coil wiring
  • Damaged or corroded connectors
  • Faulty ABS outlet valve coil
  • Short circuit in the wiring harness
  • Poor ground connection
  • Faulty ABS control module

Common misdiagnoses

  • Faulty ABS module
  • Damaged wiring or connectors
  • Faulty wheel speed sensor
  • Brake fluid level issues
  • Faulty brake pedal position sensor
  • Incorrectly installed or defective ABS pump
  • Faulty relay or fuse related to ABS system

Troubleshooting steps

  1. 1. Visual Inspection

    Wiring and Connectors: Check the wiring harness and connectors leading to the left front ABS outlet valve coil for any signs of damage, corrosion, or loose connections

  2. 2. ABS Module

    Inspect the ABS control module for any visible damage or loose connections

  3. 3. Check for Other Codes

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

  4. 4. Test the ABS Outlet Valve Coil

    Resistance Test: Use a multimeter to measure the resistance of the left front ABS outlet valve coil. Compare the reading to the manufacturer's specifications. If the resistance is out of range, the coil may be faulty

  5. 5. Power and Ground

    Check for proper voltage and ground at the connector for the outlet valve coil while the ignition is on. If there is no power or ground, trace the circuit back to the ABS module

  6. 6. Inspect the ABS Module

    If the wiring and coil are in good condition, the issue may lie within the ABS control module itself. Check for any signs of internal failure or damage

  7. 7. If possible, perform a bench test on the ABS module or consider swapping it with a known good unit for testing

  8. 8. Check for Short Circuits

    Inspect the wiring for any shorts to ground or other circuits that could cause an open circuit condition. Use a multimeter to check continuity in the wiring

  9. 9. 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

  10. 10. Consult Repair Manual

    Refer to the vehicle's service manual for specific diagnostic procedures, wiring diagrams, and specifications related to the ABS system

  11. 11. Professional Diagnosis

    If the issue persists after performing the above steps, consider seeking help from a professional mechanic or an automotive technician with experience in ABS systems.Safety Note Always ensure safety when working on vehicle electrical systems. Disconnect the battery when working on wiring and components to prevent accidental shorts or shocks. By following these steps, you should be able to identify the cause of the C1195 code and take appropriate action to resolve the issue
