Event Data Recorder Request Circuit/Open
This code is in our catalogue but has not yet been through editorial review, so the guidance below is limited to what our structured data supports. We publish deeper diagnostic content only after a code has been reviewed — here is why.
The Event Data Recorder (EDR / black box) request line — used by the ECM or restraint module to trigger the EDR to capture pre-crash data — is open. The ECM cannot trigger an event capture, so any subsequent crash event would not be recorded reliably.
A trouble code records what a control module measured. It does not identify which part failed. Test before replacing anything.
