Freeze Frame Data Mode

This mode allows access to emission related data values from specific generic PIDs. These values are immediately stored in continuous memory when an emission related fault occurs. This provides a snapshot of the conditions that were present when the fault occurred. Freeze frame will be stored until PCM memory is erased.

To access FREEZE FRAME DATA MODE, turn ignition switch to OFF position. Ensure test equipment is properly attached. Program scan tool using the following steps:

• Select vehicle and engine selection menu (optional). See Figure.
• Select year, engine, model and any additional information requested by scan tool (optional).
• Follow operating instructions from scan tool menu.
• Select GENERIC OBD-II FUNCTIONS. Press CONT button if OBD-II monitors are not complete.
• Turn ignition on.
