PTI 524247.17 – Carrier Speed Low at Start-Up
John Deere error PTI codes
This error code indicates that the carrier speed is incorrect at start-up. This can indicate a problem with the carrier speed sensor circuit, or the actual carrier speed is not responding to commands due to a possible mechanical or hydraulic control problem. This code is only generated at engine start-up and cannot be generated during…
