5. FREEZE FRAME DATA
NOTE:
• Data stored at the time of trouble occurrence is
shown on display.
• Each time trouble occurs, the latest information
is stored in the freeze frame data in memory.
• Freeze frame data will be memorized maximum
to three.
• If freeze frame data is not properly stored in
memory (due to a drop in ABSCM power supply,
etc.), a DTC, preceded by a question mark “?”, ap-
pears on the Subaru Select Monitor display. This
shows it may be an unreliable reading.
