PTQ 000191.00 – Transmission Speed Too High During Calibration
PTQ 000191.00 (PTQ 191.00)
Code: 000191.00
Shortcode: 191.00
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.
