Mode 2: Freeze Frame Data

WARNING: This page is about a different car, the 2000 Infiniti Q45 and 2000 Infiniti G20. However, it is still accessible from the selected car via links, so may be relevant.

This mode gains access to emission-related data value information stored by ECM during the freeze frame portion of self-diagnostic mode during engine operation.
