Freeze Frames The information shown in the “freeze frames” panel of VCADS Pro is an overview of values when certain fault codes become active. These values (before, during, and after the fault code appears) can be helpful to trace the problem. Freeze frames are active only when a fault code indicating a mechanical fault is set. Check the values that refer to the fault code. Example: If the value is near the alarm limit for a while before the fault code becomes active, this may indicate contamination of certain filters filters or liquids. liquids. If the value suddenly increases or decreases before the fault code becomes active, this may indicate an open circuit or short circuit. circuit.
