Description:

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.

Reaction:

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

Recommendations:

• 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.

Note:

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