The P2513: Event Data Recorder Request Circuit Low refers to an issue where the Event Data Recorder (EDR) request circuit is receiving a lower-than-expected voltage or signal. This can be due to a malfunctioning Event Data Recorder, issues in the wiring or connectors, or insufficient power supply to the EDR circuit. A malfunction in this circuit can affect the EDR’s ability to function properly during a significant event like a collision.
P2513 – Quick Overview
| Code | Information |
|---|---|
| Meaning | P2513: Event Data Recorder Request Circuit Low |
| Is it serious? | Moderately serious, as it does not affect immediate drivability but can compromise the ability to record critical vehicle data in an incident. |
| Possible causes | – Low voltage or signal in the Event Data Recorder request circuit – Faulty Event Data Recorder – Wiring or connector issues |
| How to diagnose? | – Measure the voltage and signal in the Event Data Recorder request circuit – Inspect and test the Event Data Recorder – Check wiring and connectors – Replace faulty components if needed |
Code Meaning
The P2513: Event Data Recorder Request Circuit Low code indicates that there is insufficient voltage or a weak signal being detected in the Event Data Recorder (EDR) request circuit. This condition could be the result of a power supply issue, a defective EDR, or problems in the wiring or connectors leading to the EDR. Proper voltage is essential for the EDR to record data accurately in case of an event.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to determine if there are additional related codes. These may provide more context or clues regarding the power supply issue. | OBD-II Scanner |
| Measure Voltage in the EDR Request Circuit | Use a multimeter to measure the voltage in the EDR request circuit. Compare the readings to manufacturer specifications to determine if the voltage is lower than required. | Multimeter |
| Inspect the Event Data Recorder | Inspect the EDR for any visible signs of damage, and ensure that it is properly connected. A damaged or disconnected EDR may result in a low circuit signal. | Flashlight, Diagnostic Tool |
| Check Wiring and Connectors | Examine all connectors and wiring associated with the EDR. Look for loose, corroded, or damaged connectors and wiring that may be leading to a weak or low signal. Repair any issues found. | Flashlight, Multimeter |
| Test the Event Data Recorder | Use a diagnostic tool to test the functionality of the EDR. Ensure it is receiving the correct power and can perform its intended operations. Replace the EDR if it is found to be faulty. | Diagnostic Tool, Multimeter |
| Check for Power Supply Issues | Inspect the power supply to the EDR. Ensure that the battery and any related fuses are functioning properly and that there are no issues causing low voltage to reach the EDR. | Multimeter, Battery Tester |
| Replace Faulty Components | If the EDR, wiring, or connectors are determined to be faulty, replace them as necessary. Ensure that all replacement parts meet the vehicle’s specifications. | Replacement Parts, Vehicle Owner’s Manual |
| Clear the Code and Test | Clear the P2513 code using an OBD-II scanner after making the necessary repairs. Run a system test to confirm that the EDR circuit is now operating within the correct parameters. | OBD-II Scanner, Vehicle Owner’s Manual |
| Recheck for Codes | Re-scan the vehicle to confirm that the P2513 code has not returned. If the code reappears, further diagnostics may be needed to identify other potential faults. | OBD-II Scanner |
