Description:

This code is stored when the transmission is being shifted from 3R to 4R or 5R while the engine RPM is below the minimum engine speed value programmed in the PTP. This situation can lead to excessive engine load and potential damage.

Reaction:

The control unit limits the functionality to protect the transmission and engine from excessive load.

Recommendations:

• Maintain Engine Speed:
  Ensure the engine RPM is above the minimum required speed when shifting from 3R to 4R or 5R.
• Operator Training:
  Educate operators on the correct shifting procedures to avoid engine load issues.
• Transmission Inspection:
  Check the transmission for any issues that may cause excessive load during shifts.
• Consult Manual:
  Refer to the operator’s manual for the correct operational procedures to avoid inducing this error.

Note:

This code can be operator-induced, so proper training and adherence to operational procedures are critical to prevent this issue. Regular maintenance and monitoring of engine and transmission performance are also essential.
