P2514: Event Data Recorder Request Circuit High

What it means

The event data recorder request circuit signal is above the expected range. The code does not establish the circuit’s request logic or the effect on event recording.

At a glance

• Usually lights the check-engine light

How it works

The event data recorder (EDR) request circuit carries a request signal that the vehicle control module monitors. P2514 sets when that signal is above its expected range, which can happen if the request wire contacts battery voltage; the code does not determine whether recording is affected.

Common causes

Most likely first.

1. Request wire shorted to battery voltage
2. Connector pins corroded - high contact resistance
3. Supply wire pinched against B+ source

Symptoms

• Check-engine light
• Event-data-recorder warning or service message, if equipped
• No noticeable driving symptoms may occur

How to diagnose it

1. Review freeze-frame data and any EDR or service message to see when the high request-circuit signal was detected.
2. Use vehicle wiring information to locate the EDR request circuit and inspect for pinched or chafed wiring near power feeds.
3. Check the connector for corrosion, damaged pins, or a poor connection that could disrupt the request signal.
4. Test the request wire for a short to battery voltage and check its continuity using the specified circuit procedure.
5. Compare the circuit signal and EDR input with the manufacturer's specification before identifying a module fault.

Common fixes

• Repair a request wire shorted to battery voltage.
• Repair pinched harness insulation where the wire contacts a power source.
• Clean or replace damaged EDR request-circuit connector terminals.
• Repair or replace a failed EDR input stage if the wiring tests correctly.

Can I keep driving?

The code may not affect normal driving, but it can leave the EDR request function or event recording uncertain. Arrange repair soon and avoid disturbing restraint-system wiring.
