What Does P2514 Mean?
The PCM has detected a high voltage condition in the event data recorder request circuit. This indicates the signal voltage exceeds the expected threshold for proper EDR communication.
Common Causes
40%
Short to voltage in EDR request circuit wiring
30%
Faulty airbag control module sending incorrect high signal
20%
Damaged or corroded connector causing voltage bleed from adjacent circuits
10%
PCM internal failure in EDR input protection circuit
Diagnostic Steps
1
Step 1: Measure actual voltage on EDR request circuit at PCM connector with key on
2
Step 2: Disconnect airbag control module and verify voltage drops to zero
3
Step 3: Inspect wiring for damage or contact with power sources along entire harness route
4
Step 4: Check for water intrusion or corrosion in connectors that could cause cross-circuit contamination
5
Step 5: Test airbag control module output with scan tool commands if capable
Estimated Repair Cost
$150 - $1,500
Parts + labor, varies by vehicle and location
The PCM has detected a high voltage condition in the event data recorder request circuit. This indicates the signal voltage exceeds the expected threshold for proper EDR communication.
The most common cause of P2514 (Event Data Recorder Request Circuit High) is: Short to voltage in EDR request circuit wiring
Typical repair costs for P2514 range from $150 to $1,500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Does not affect normal vehicle operation or airbag system function. May compromise accident data recording capability.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2514 to identify the root cause.
