P2512: Event Data Recorder Request Circuit/Open
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.
What P2512 means
P2512 is a generic OBD-II body code in the other body group. In plain English: the computer found an electrical fault in that circuit: an open, short or bad connection, or a failed component.

Can I drive with P2512?
Usually yes, for a short time.
The car will often drive normally, but get it diagnosed soon. If you notice rough running, warning lights flashing, overheating or a burning smell, stop driving.
Why we rate it moderate
- Turns on the check engine light
Severity is our rule-based rating from the code’s flags in OBDex and the system it affects, not an inspection of your car. If the check engine light is flashing, or you notice overheating, low oil pressure, or brake or steering problems, stop driving and get help.
How to diagnose P2512
- 1
Confirm the code and save freeze-frame data
Read the codes with an OBD-II scan tool and note every code, not just P2512. Save the freeze-frame data (speed, load, temperature when the fault set) before clearing anything; it tells you when the fault happens.
- 2
Fix other faults first
If other codes are stored, start with power-supply, sensor-circuit and communication codes. They can cause this code as a side effect.
- 3
Test the circuit
Inspect the wiring and connector at the event data recorder and request wire for damage, corrosion or chafing. With a multimeter, check supply voltage, ground and signal against the specifications in the service manual for your vehicle.
- 4
Test the likely causes in order
Start with the most likely cause and work down: Open request wire or unplugged module; failed input stage in the EDR; pin pushed back out of connector body. Test before replacing parts.
- 5
Check for recalls and service bulletins
Look up recalls for your exact vehicle with its VIN, and ask a dealer about technical service bulletins (TSBs). Manufacturers sometimes issue software updates or extended warranties for known faults.
- 6
Clear the code and verify the repair
After the repair, clear the code and drive the car under the conditions in the freeze-frame data to confirm it does not return.

P2512 FAQ
What does P2512 mean?
P2512 means “Event Data Recorder Request Circuit/Open”. 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.
Is P2512 serious? Can I keep driving?
We rate P2512 as moderate severity. Usually yes, for a short time. The car will often drive normally, but get it diagnosed soon. If you notice rough running, warning lights flashing, overheating or a burning smell, stop driving.
What causes P2512?
The most common causes, from most to least likely: Open request wire or unplugged module; Failed input stage in the EDR; Pin pushed back out of connector body. Test before replacing parts, because several causes can set the same code.
How much does it cost to fix P2512?
Typical labor is about $65–$250 at an assumed $125/hour shop rate, plus parts. That is an estimate, not a quote: labor times and rates vary by vehicle and region, and diagnosis may be billed separately.
Can I fix P2512 myself?
DIY difficulty is moderate. Most owners leave this to a shop because it needs involved testing or specialist tools. Always confirm the cause before buying parts.
Will P2512 clear itself?
If the fault was intermittent, the warning may go off once the computer stops seeing it, but the code stays in memory. Fix the cause; clearing the code alone doesn’t repair anything.
