Diagnostic Aids

Many tables have one result which reads Fault Not Present or Go to Diagnostic Aids. Fault Not Present indicates that the conditions that were present when the DTC set are no longer there. A driveability concern can often be identified by using the Freeze Frame or Failure Records, or the information from the driver. The Diagnostic Aids information may tell to the technician what to look for and where to investigate, in order to diagnose an intermittent failure.
