Event Data Recorder Request Circuit Open
The P2512 code indicates an open circuit in the Event Data Recorder (EDR) request circuit. The EDR is part of the airbag system and records vehicle data during a crash event. An open circuit means there is a break in the electrical path, preventing the EDR from receiving or sending signals. This can be caused by damaged wiring, loose connectors, or a faulty EDR module.
1. Most Common Causes
- Damaged or corroded wiring in the EDR request circuit
- Loose or disconnected electrical connector at the EDR module
- Faulty EDR module
2. Symptoms You Will Notice
- Airbag warning light illuminated
- Event data recorder may not function during a crash
3. Step-by-Step Diagnosis
Step 1: Use a scan tool to retrieve all codes and freeze frame data.
Step 2: Visually inspect the EDR module and its wiring harness for damage, corrosion, or loose connections.
Step 3: Check continuity of the EDR request circuit using a multimeter; repair or replace any open wires.
Step 4: If wiring is intact, test the EDR module per manufacturer procedure and replace if faulty.
