C1164 Park Brake Actuator Assembly Switch Circuit Failure

The OBD2 code C1164 indicates a malfunction in the park brake actuator assembly switch circuit, which may involve issues with the switch itself, wiring, or connections related to the park brake system

Definition

The OBD2 code C1164 indicates a malfunction in the park brake actuator assembly switch circuit, which may involve issues with the switch itself, wiring, or connections related to the park brake system

Common causes

  • Faulty park brake actuator assembly
  • Damaged wiring or connectors
  • Corroded terminals
  • Failed park brake switch
  • Short circuit in the circuit
  • Open circuit in the circuit
  • Poor ground connection
  • Malfunctioning control module

Common misdiagnoses

  • Faulty park brake actuator
  • Malfunctioning brake switch
  • Wiring issues or shorts in the circuit
  • Defective brake control module
  • Low brake fluid level
  • Faulty ABS module
  • Incorrectly installed or damaged park brake assembly

Troubleshooting steps

  1. 1. Check the Vehicle's Manual

    Refer to the vehicle's service manual for specific information related to the park brake actuator and the associated switch circuit

  2. 2. Visual Inspection

    Wiring and Connectors: Inspect the wiring harness and connectors related to the park brake actuator for any signs of damage, corrosion, or loose connections

  3. 3. Park Brake Assembly

    Check the park brake assembly itself for any physical damage or misalignment

  4. 4. Scan for Additional Codes

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

  5. 5. Test the Park Brake Switch

    Functionality: Test the park brake switch to ensure it is functioning correctly. You can do this by checking for continuity when the switch is engaged

  6. 6. Voltage Check

    Use a multimeter to check for proper voltage at the switch when the park brake is applied and released

  7. 7. Inspect the Actuator

    Operation: If possible, manually test the park brake actuator to ensure it operates correctly. This may involve applying power directly to the actuator to see if it responds

  8. 8. Resistance Check

    Measure the resistance of the actuator to ensure it is within the manufacturer's specifications

  9. 9. Check for Ground Issues

    Ensure that the ground connections for the park brake actuator and switch are secure and free of corrosion

  10. 10. Test the Control Module

    If applicable, check the vehicle's control module for any faults. This may involve checking for software updates or reprogramming if necessary

  11. 11. Inspect Related Components

    Check other components that may be related to the park brake system, such as fuses, relays, and any associated sensors

  12. 12. 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

  13. 13. Consult a Professional

    If the issue persists after performing these steps, it may be necessary to consult a professional mechanic or technician who has access to specialized diagnostic tools and equipment.Additional Tips: - Always ensure safety when working on a vehicle, especially when dealing with electrical components. - Document any changes or repairs made during the troubleshooting process for future reference. By following these steps, you should be able to identify and resolve the issue related to the C1164 code
