DTC And Freeze Frame Data

ON BOARD DIAGNOSTIC (OBD) SYSTEM

DTC and Freeze Frame Data

VCM can save multiple DTC but can only save 1 freeze frame data record.
When VCM detects a certain malfunction, if it detects a different malfunction after saving the DTC and freeze frame data, multiple DTC can be confirmed, but only the freeze frame data that is saved first can be confirmed.
The DTC and freeze frame data are deleted when the self-diagnostic is deleted.
