Description:

This diagnostic trouble code is generated if the control software detects that the current value at the solenoid for Gear 1 is too low. This condition typically indicates an open circuit, which could be due to wiring issues, a faulty solenoid, or connector problems.

Reaction:

The control software may restrict the engagement of Gear 1, potentially affecting the transmission’s performance and overall operation of the equipment.

Recommendations:

• Inspect Wiring and Connectors:
  • Check for any loose, damaged, or corroded wires and connectors leading to the Gear 1 solenoid. Repair or replace as necessary.
• Test Solenoid:
  • Test the Gear 1 solenoid to ensure it is functioning correctly. Replace the solenoid if it is found to be defective.
• Measure Current:
  • Use a multimeter to measure the current at the solenoid. Ensure the current is within the specified range.
• Consult Technical Support:
  • If the issue persists after performing the above checks, consult technical support or the manufacturer for further assistance.

Note:

Regular inspection and maintenance of the electrical system can help prevent solenoid-related issues and ensure reliable operation of the transmission.
