The P2513 code indicates that the Event Data Recorder (EDR) request circuit is experiencing a low voltage condition. This circuit is used to trigger the EDR to record crash data during an impact. A low signal may prevent the EDR from functioning properly.
A short to ground, open circuit, or high resistance in the wiring between the EDR module and the requesting module (often the airbag control unit) is the most common cause.
The EDR module itself may be defective, especially if it is integrated into the airbag control module or restraints control module.
Corrosion, bent pins, or loose connections at the EDR module or related control unit connectors can cause low voltage in the request circuit.
If the RCM is separate from the EDR, a malfunction in the RCM can send an incorrect low signal on the request circuit.
In very rare cases, the PCM may have an internal fault causing it to incorrectly read or output the EDR request circuit signal. This should only be considered after all other causes are ruled out.
An Event Data Recorder is a device that records vehicle data such as speed, brake application, and seat belt status in the moments before, during, and after a crash. It is often integrated into the airbag control module.
Yes, the vehicle is typically drivable, but the EDR may not record crash data, and the airbag system might be affected. It is advisable to have the issue diagnosed and repaired to ensure safety systems function correctly.
No, the PCM is rarely the cause. Wiring faults, connector issues, or a faulty EDR module (often part of the airbag control module) are far more common. Replacing the PCM without thorough diagnosis is usually a mistake.
It depends on the vehicle. In some models, the PCM monitors this circuit and will illuminate the Check Engine Light. In others, only the airbag warning light may come on, and the code is stored in the airbag module.
