Event Data Recorder Request Circuit Low
The P2513 code indicates that the Powertrain Control Module (PCM) has detected a low voltage condition in the Event Data Recorder (EDR) request circuit. This circuit is used by the PCM to communicate with the EDR module, which records vehicle data during crash events. A low voltage signal suggests a short to ground, open circuit, or faulty component in the wiring or connectors between the PCM and EDR module.
1. Most Common Causes
- Short to ground in the EDR request circuit wiring
- Open circuit or high resistance in the EDR request circuit
- Faulty EDR module
- Corroded or damaged connectors in the circuit
- Failed PCM (rare)
2. Symptoms You Will Notice
- Check Engine Light illuminated
- Possible airbag system warning light
- EDR may not record crash data
- No drivability issues typically present
3. 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 loose connections.
Step 3: With key on engine off, measure voltage at the EDR module connector on the request circuit. Expected voltage is near battery voltage (12V). If low, check for shorts or opens.
Step 4: Disconnect the PCM and EDR module, check continuity and resistance of the circuit. Repair or replace as needed.
Step 5: If wiring is okay, replace the EDR module and clear codes. Test drive to verify repair.
4. Frequently Asked Questions
Is it safe to drive with this code?▼
Yes, the vehicle is generally safe to drive as the code does not affect engine or transmission performance. However, the EDR may not record data in a crash, which could be important for insurance or legal purposes.
How much does it cost to fix?▼
The cost typically ranges from $50 to $150 for diagnosis and repair, depending on the cause. If the EDR module needs replacement, parts can add $100-$300.
5. Commonly Affected Makes
