Description:

This diagnostic trouble code, PTQ 000191.00, is generated when transmission speed is detected during the calibration process. This can occur due to a defective transmission speed sensor or if the tractor is not positioned on a level surface during calibration, leading to potential movement of the tractor.

Reaction:

When this error is detected, the control software cancels the transmission calibration process to prevent inaccurate calibration.

Recommendations:

Check Transmission Speed Sensor:

• Inspect the transmission speed sensor for any signs of damage or malfunction.
• Replace the sensor if it is found to be defective.

Ensure Level Surface:

• Make sure the tractor is positioned on a completely level surface before initiating the calibration process.
• Reattempt calibration in a different location if necessary to ensure stability.

Verify CAN BUS Data:

• Ensure that the transmission speed data received via the CAN BUS is accurate.
• Check the CAN BUS wiring and connections for any loose connections, damage, or corrosion. Repair or replace as necessary.

Software Update:

• Verify that the control software is up-to-date with the latest version.
• Update the software if there are any available updates to improve calibration accuracy and error handling.

Monitor Calibration Process:

• After addressing the above steps, restart the transmission calibration process.
• Observe the system to ensure the calibration completes without further errors.

Note:

• Regular maintenance and inspection of the transmission speed sensors and CAN BUS system are crucial for preventing this type of error.
• If the issue persists despite taking the above measures, consult technical support or the manufacturer for further assistance.
