  • Retrieve and document the error codes.
  • Research the codes to determine the specific repairs needed based on manufacturer specifications.
3. Inspect and Repair Components
  • If the error codes indicate specific components (e.g., oxygen sensors, catalytic converter), proceed to:
    • Remove the component (if necessary):
      • Use socket set to unbolt and disconnect the component.
    • Inspect the component for damage or wear.
    • Replace with a new part if it is faulty. Ensure you use OEM or high-quality aftermarket parts.
4. Reset the System
