I have a D3512 that periodically spits out an Accelerator Pedal Position 1, Calibration Required. SPN 91 FMI 13. We don't even have accelerator pedals as this is a marine installation. It goes away after resetting power and doesn't come on regularly. It's more of a nuisance. This engine has the second generation wiring harness with the Marine Power Display unlike the relay panel in the previous question.
