Diagnostic Aids

Use Freeze Frame and Failure Records data in order to locate an intermittent condition. If you cannot duplicate DTC, information included in Freeze Frame and Failure Records data may aid in determining number of miles since DTC set. Fail Counter and Pass Counter can also aid in determining number of ignition cycles that diagnostic test reported a pass and/or fail. Operate vehicle within same freeze frame conditions (RPM, engine load, vehicle speed, temperature, etc.). This will isolate when DTC failed
