P2512 code meaning
Event Data Recorder Request Circuit/Open
What P2512 means
P2512 concerns the wired request line between the event data recorder and the engine module. The recorder, normally part of the airbag control unit, stores a short history of speed, throttle, brake and other pre-crash data when it senses a crash or near-crash, and needs powertrain values for that. Via the request circuit it can ask the engine module to deliver or freeze them. P2512 means the module sees this circuit as open or not in its expected state. Ford lists P2512 for the 2014 BOSS 302S engine module with a W rather than an M in its indicator column; no maker publishes wiring or thresholds. Low and high states are P2513 and P2514. The fault does not affect driving or emissions but may leave crash data incomplete.
P2512 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.5 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2512
- Code stored without noticeable symptoms
- Possibly a service or wrench indicator
Common causes of P2512
- Most likelyRequest wire broken or connector unplugged
- PossibleAirbag/recorder module missing, replaced or not configured
- Less likelyEngine module configured for a recorder line that is not fitted
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2512 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 5 | Area: vehicle speed, idle control and auxiliary inputs. |
| 12 | The exact fault in that area. |
What to do next
- Note P2512 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2512
What does P2512 mean?
P2512 means "Event Data Recorder Request Circuit/Open". P2512 concerns the wired request line between the event data recorder and the engine module. It is a generic code, so it means the same on every make.
Is it safe to drive with P2512?
P2512 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P2512 fail an emissions test?
P2512 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P2512 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2 hours of work. This is a job for a workshop.
Will P2512 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
