Scan Tool
WARNING: This page is about a different car, the 2003 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.
The scan tool features that can be used to locate an intermittent conditions source include the following:
- Scan Tool Snapshot Feature - The scan tool snapshot feature can be triggered to capture and store engine parameters when a malfunction occurs. This stored information can be reviewed and compared to the Engine Scan Tool Data List or data values taken from a similarly equipped known good vehicle.
- Freeze Frame/Failure Records Data Feature - Freeze Frame/Failure Records are stored when certain DTCs set. They typically include information to aid in reproducing the driving conditions that were present when a DTC is stored. In addition, engine parameters are also stored. This stored information can be reviewed and compared to the Engine Scan Tool Data List or data values taken from a similarly equipped known good vehicle. Freeze Frame/Failure Records data will be erased when DTC information is cleared either by scan tool clearing or by disconnection of the control modules power supply.
