Possible causes | – Open circuit in the Event Data Recorder request circuit – Faulty Event Data Recorder – Wiring or connector issues |
How to diagnose? | – Inspect the Event Data Recorder request circuit for open circuits – Test the Event Data Recorder – Check wiring and connectors – Replace faulty components if needed |
Code Meaning
The P2512: Event Data Recorder Request Circuit/Open code indicates that there is an open circuit or some issue preventing the Event Data Recorder from receiving or sending signals correctly. This could be due to damaged wiring, poor connections, or a faulty Event Data Recorder module itself. The EDR is critical for storing vehicle information during an event like a crash, which can be important for analysis and diagnostics.
Step-by-step diagnostic guide
Action | Description | Tools Needed |
---|---|---|
Check for Other Codes | Use an OBD-II scanner to check for any additional related codes. These codes may provide more context or help locate related issues within the circuit. | OBD-II Scanner |
Inspect the EDR Request Circuit | Visually inspect the Event Data Recorder (EDR) request circuit for any open circuits, damaged wiring, or loose connections. Look for physical damage such as frayed wires or disconnections. | Flashlight, Multimeter |
Check Wiring and Connectors | Examine all connectors and wiring related to the EDR request circuit. Make sure there are no loose or corroded connections that could cause an open circuit. Repair or replace any faulty wiring or connectors. | Flashlight, Multimeter |
Test the Event Data Recorder (EDR) | Use a diagnostic tool to test the functionality of the Event Data Recorder. Confirm that it is properly responding to requests and is capable of receiving and sending signals as expected. | Diagnostic Tool |
Check for Open Circuit Continuity | Use a multimeter to check for continuity in the request circuit wiring. An open circuit will show no continuity. Trace and repair any open areas found. | Multimeter |
Replace Faulty Components | If any components are determined to be faulty, such as the EDR itself or any wiring/connectors, replace them with suitable parts to ensure correct operation. | Replacement Parts, Vehicle Owner’s Manual |
Clear the Code and Test | After making necessary repairs, clear the P2512 code using an OBD-II scanner. Perform a system test to ensure that the EDR circuit is now functioning correctly and that no new codes are set. | OBD-II Scanner, Vehicle Owner’s Manual |
Recheck for Codes | Re-scan the vehicle after the test to ensure the P2512 code has not returned. If the code reappears, further diagnosis may be needed to locate additional faults. | OBD-II Scanner |
