  1. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
  1. Use the approved diagnostic system or a scan tool to retrieve any diagnostic trouble codes (DTCs) before moving onto the symptom chart or DTC index.
      • Because the DTCs are stored in more than one module, a complete vehicle read is recommended.
      • Make sure that all DTCs are cleared following rectification
