Diagnostic Aids

Diagnostic Aids provide helpful information when the conditions that caused the DTC or driveability problem is not currently present. Sometimes, with the help of snapshot on DTC set data (Freeze Frame or Failure Records) or information from the driver, the problem may still be identified or at least 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.
