Code P2512: Event Data Recorder Request Circuit/ Open
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.
