Failure Cause:
The system cannot retrieve nozzle status information due to damaged spray nozzle actuators preventing data transmission.

Troubleshooting Steps:

1. ​Inspect Actuator Interfaces:

   • Check for loose connections at the actuator interfaces.
   • Verify continuity between the actuator and main control unit (MCU).

2. ​Check Boom Wiring Harnesses:

   • Examine the forward/backward boom wiring harnesses for damage or improper connections.

3. ​Actuator Interface Validation:

   • Physically inspect all actuator interfaces at the spraying components for corrosion or wear
