Event Data Recorder Request Circuit High
The P2514 code indicates that the powertrain control module (PCM) has detected a high voltage condition in the event data recorder (EDR) request circuit. This circuit is used by external diagnostic tools to request data from the vehicle's EDR. A high voltage reading typically suggests a short to power, a faulty EDR module, or a wiring issue. The code is set when the voltage exceeds the manufacturer's specified threshold.
01. Most Common Causes
- Short to power in the EDR request circuit wiring
- Faulty event data recorder (EDR) module
- Damaged connector or terminal in the EDR circuit
- Corrosion or moisture in the EDR circuit
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Possible inability to retrieve EDR data during diagnostics
- No other drivability issues typically present
03. Step-by-Step Diagnosis
Step 1: Use a scan tool to retrieve all stored codes and freeze frame data.
Step 2: Visually inspect the EDR request circuit wiring and connectors for damage, corrosion, or shorts.
Step 3: Measure voltage at the EDR request circuit with the ignition on; compare to manufacturer specifications.
Step 4: If voltage is high, isolate the circuit and check for shorts to power; repair as needed.
Step 5: If wiring is intact, test the EDR module per service manual; replace if faulty.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
Yes, the vehicle is generally safe to drive as this code does not affect engine performance or safety systems. However, the Check Engine Light will remain on, and EDR data retrieval may be unavailable.
How much does it cost to fix?▼
Repair costs typically range from $100 to $300, depending on the cause. Wiring repairs are usually cheaper, while replacing the EDR module can be more expensive.
