Formula

Hybrid/EV system data (J1979-DA)

• Also valid as Mode 02 freeze-frame data (same PID number, snapshot at last DTC).
• Hybrid-related standard PID. Many EU HEV/PHEV ECUs still hide pack data behind a manufacturer request. See standard vs manufacturer.

Defined by SAE J1979 / ISO 15031-5. Public index — not a substitute for the paid SAE document.
