Description:

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

Reaction:

The control unit limits the functionality of the equipment to prevent potential damage.

Recommendations:

• Inspect Speed Sensors:
  • Check the speed sensors for the hydro ring gear, engine, carrier, and output for proper operation.
  • 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 PTI control unit is functioning correctly and processing speed data accurately.
  • Update or reprogram the control unit if needed.

Note:

Accurate speed matching across different components is essential for optimal performance and preventing mechanical issues.
