Diagnostic Aids

The Diagnostic Aids provide helpful information when the conditions that caused the DTC or driveability problem are not currently present. Sometimes, with the help of the Freeze Frame or Failure Records, or information from the driver, the problem may still be identified or narrowed down to a short list of possible intermittent conditions. When this is true the Diagnostic Aids may explain what to look for, and the most logical path to locate an intermittent condition.
