Diagnostic Aids

Many tables have one result which reads Fault Not Present or Go to Diagnostic Aids. Fault Not Present means that the conditions (failures) that were present when the DTC set are no longer there. Sometimes, with the help of snapshot information (Freeze Frame or Failure Records) or information from the driver, the driveability concern may still be identified or narrowed down to a short list of possible intermittent or related system failures. The Diagnostic Aids information may tell to the technician what to look for and where to investigate, in order to diagnose an intermittent failure.
