Description:

This error code is triggered when no tractor speed is detected after the speed control lever is placed in gear and a wheel speed greater than 1 km/h (0.62 mph) is commanded. If DTCs PTI 000754.18, PTI 000755.18, or PTI 000756.18 are present, they should be diagnosed before proceeding with the current diagnosis.

Reaction:

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

Recommendations:

• Inspect Speed Sensors:
  • Check the speed sensors for proper operation and ensure they are detecting wheel speed accurately.
• Verify Gear Engagement:
  • Ensure that the transmission is properly engaging when the speed control lever is placed in gear.
• Diagnose Related DTCs:
  • If PTI 000754.18, PTI 000755.18, or PTI 000756.18 codes are present, diagnose and resolve these issues first.
• Check for Mechanical Issues:
  • Inspect for any mechanical issues that could prevent the tractor from moving, such as brakes being engaged or drive components being disconnected.

Note:

Accurate detection of tractor speed and proper gear engagement are critical for effective operation. Addressing related DTCs and ensuring sensor functionality can prevent this issue.
