Freeze Frame Data Mode

This mode allows access to data values captured during a malfunction that caused a DTC to set. These values are immediately stored in continuous memory when an emission related fault occurs. This provides a snapshot of conditions present when fault occurred. Freeze frame data will be stored until PCM memory is erased. Misfire fault data may override less important fault data.

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

• Select year, engine, model and any additional information requested by scan tool (optional).
• Follow operating instructions from scan tool menu.
• Select DIAGNOSTIC FUNCTIONS. Press CONT button if OBD-II System Readiness Tests (SRT) are not complete.
• Turn ignition on.
• Select FREEZE FRAME PID REQUEST.
