Description:

This diagnostic trouble code is generated if the control software detects that the current value at the Park Lock Solenoid 1 in the DirectDrive Transmission is too low. This may indicate an open circuit or other issues affecting the current flow.

Reaction:

When this error occurs, the park lock functionality may be compromised, potentially preventing the equipment from being securely locked in place when parked.

Recommendations:

• Inspect Solenoid Wiring:
  • Check for any visible signs of damage, wear, or disconnection in the solenoid wiring.
  • Ensure all connections are secure and free of corrosion.
• Test Solenoid Function:
  • Use a multimeter to measure the current at the solenoid and verify it is within the specified range.
  • Replace the solenoid if it is not functioning correctly.
• Check for Open Circuits:
  • Inspect the wiring for any open circuits that could be causing the low current issue.
  • Repair or replace any damaged wiring as necessary.
• Verify Power Supply:
  • Ensure that the power supply to the solenoid is stable and providing the correct voltage.
  • Check for any issues with the power source or connections.

Note:

• Regular inspection and maintenance of the solenoid and its wiring can prevent current-related issues.
• Ensure that environmental factors, such as moisture or debris, are not affecting the solenoid’s operation.
