PTI 524247.02 – Carrier Speed Incorrect

PTI 524247.02 (PTI )

Code: 524247.02



This error code is triggered when the carrier speed does not match the expected speed. The carrier speed is compared to engine speed, ring gear speed, and output speed.


The control unit commands the equipment to enter Park mode, which is recoverable.


  • Inspect Speed Sensors:
    • Check the speed sensors for the carrier, engine, ring gear, and output to ensure they are functioning correctly.
    • Replace any faulty sensors.
  • Verify Speed Calibration:
    • Ensure that the speed calibration settings are correct and align with the expected parameters.
    • Recalibrate the system if necessary.
  • Evaluate Control Unit:
    • Verify that the control unit is functioning correctly and processing speed data accurately.
    • Update or reprogram the control unit if needed.
  • Check for Mechanical Issues:
    • Inspect for any mechanical issues that may affect carrier speed, such as worn components or hydraulic problems.
    • Repair or replace any faulty parts.


Accurate speed sensing and comparison are essential for maintaining proper transmission operation and preventing mechanical issues.
