What Does P2513 Mean?
The PCM has detected a low voltage condition in the event data recorder request circuit. This indicates the signal voltage is below the expected threshold for proper EDR operation.
Common Causes
35%
Short to ground in EDR request circuit wiring
30%
Faulty airbag control module with low output signal
20%
Damaged connector pins causing partial short to ground
15%
PCM internal fault in EDR input circuit
Diagnostic Steps
1
Step 1: Measure voltage on EDR request circuit at PCM connector with key on
2
Step 2: Disconnect airbag control module and recheck circuit voltage to isolate short location
3
Step 3: Inspect wiring harness routing for pinch points or areas rubbing against chassis ground
4
Step 4: Test resistance to ground on EDR request circuit wire with all modules disconnected
5
Step 5: Verify airbag control module output signal using oscilloscope or advanced scan tool
Estimated Repair Cost
$150 - $1,500
Parts + labor, varies by vehicle and location
The PCM has detected a low voltage condition in the event data recorder request circuit. This indicates the signal voltage is below the expected threshold for proper EDR operation.
The most common cause of P2513 (Event Data Recorder Request Circuit Low) is: Short to ground in EDR request circuit wiring
Typical repair costs for P2513 range from $150 to $1,500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Does not impact vehicle drivability or airbag deployment function. May prevent accurate crash data storage for post-accident analysis.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2513 to identify the root cause.
