Fault Family System: Powertrain (P-Codes) 3 SAE Codes

EDR Request Circuit

Diagnostic & Technical Explanation

Code P2512 (Event Data Recorder Request Circuit/ Open) sets when the ECM detects an open circuit, out-of-range voltage, or a high condition on the request line used by the event data recorder (crash data module) to pull vehicle parameters from the ECM. Causes are a corroded connector between the modules, damaged wiring on the shared request circuit, or a fault in the requesting module itself.

These 3 diagnostic trouble codes share one detection mechanism and one repair path, which is why MechanicDB groups them into a single authored fault family rather than repeating the same explanation 3 times.
