What the P2510 code means

P2510 is an OBD-II generic code for the engine control module detecting the ignition relay is open or shorted causing the relay to not come on or turn off.

What causes the P2510 code?

The ECM is detecting a signal through the ignition control relay and the relay contacts failed to close when commanded to close or the relay would not turn off when commanded to turn off.

  • The Check Engine Light will be illuminated and the code is set in ECM memory as a fault. The light will stay on unless the problem goes away for at least 3 engine key cycles.

  • The vehicle may not start or may not shut off when turning the key to start or turn off the vehicle.

  • The OBD2 scanner port will not be able to access the ECM.

How does a mechanic diagnose the P2510 code?

  • Scans for codes and documents any in the ECM to look at the freeze frame data for the failure

  • Checks ignition relay for loose or corroded pins

  • Checks ignition fuses in the main fuse box for connections

  • Installs a known good relay and tries to start the vehicle

  • Checks the connector and wiring for corrosion, causing an open in the relay circuit

Common mistakes when diagnosing the P2510 code

  • Clearing ECM memory codes before checking the freeze frame data for the main failure problem, so the failure may be duplicated and repaired

  • Failing to clear the ECM codes after the codes are fixed

  • Replacing the ECM when no communication is found when it is the ignition relay

How serious is the P2510 code?

Code P2510 is an indication that the ECM signal from the ignition relay is open or shorted and the engine may not start or shut down.
