P2512
Event Data Recorder Request Circuit/Open
Computer/data network
Generic OBD-II
Low
What it means
P2512 means the ECM has detected an open (or otherwise faulty) circuit on the line used to request the event data recorder — the module that logs vehicle data around certain events. It's a signaling/wiring fault: the engine runs normally and there's no drivability impact. The usual causes are an open circuit, a bad connector, or, less often, the requesting module itself.
Low
Can I keep driving? Yes — the car drives normally; this is a data-recorder request signal fault with no effect on engine operation.

How to diagnose & fix
Work through it in order
- Read all stored codes; address any communication or module faults alongside this one.
- Inspect the wiring and connectors between the event data recorder and the module that requests it.
- Check the request circuit for continuity and for an open back to the module.
- Repair damaged wiring or connectors, then clear the code and re-test.
- If the circuit checks out, suspect the requesting module and consult manufacturer service data.
FAQ
Quick answers
Is it safe to drive with P2512?+
Yes. This code concerns the event data recorder request line, not engine or safety-critical running, so the car drives normally. Have it looked at to clear the light.
Can I just clear P2512?+
You can, but if the circuit is open it returns. Repair the wiring or connector first.
