The diagnostic trouble code 52 indicates a high resistance in the driver-side airbag squib circuit. The airbag squib is responsible for deploying the driver-side airbag in the event of a collision.

Here are some possible causes and solutions for this issue:

  1. Faulty wiring or connectors: Inspect the wiring harness and connectors associated with the driver-side airbag squib circuit. Look for any signs of damage, loose connections, or corrosion. Repair or replace any damaged wiring or connectors as needed. Ensure that the connections are secure and properly seated.
  2. Faulty airbag squib: The driver-side airbag squib itself may be faulty and causing the high resistance. In this case, the squib should be inspected and replaced if necessary. Consult the vehicle’s service manual for the specific testing procedures for the airbag squib.
  3. Clock spring malfunction: The clock spring is a component that allows for electrical connections between the steering wheel and the rest of the vehicle. A faulty clock spring can cause issues with the driver-side airbag squib circuit. Have the clock spring tested and replaced if necessary.
  4. Diagnostic equipment malfunction: In some cases, the diagnostic equipment used to read the trouble code may be faulty or not providing accurate information. Consider using a different diagnostic tool or consult a professional mechanic to verify the diagnosis.

It’s important to address this issue as soon as possible to ensure the proper functioning of the driver-side airbag in case of an accident. If you are unsure or uncomfortable performing these steps yourself, it is recommended to seek assistance from a qualified mechanic or dealership. They will have the expertise and tools to accurately diagnose and resolve the high resistance issue indicated by the diagnostic trouble code 52.
