Troubleshooting The Display Module and Control Module work as a system and communicate with each other over the CAN bus. Both modules should be powered up at the same time for proper functionality. Display Module Error Codes 17 LP69910 (12/07/2020) 3 CU FT GATOR FERTILIZER SPREADER Symptom Troubleshooting Guide Control Module and/or Display Module does not turn on Control Module status light is off Display Module screen is off and/or status LED is off 1. Ensure connections are fully seated. 2. Remove front wire harness. Check for 12v at pins A-J at rear connection attachment point. 3. If no voltage, vehicle has insufficient power or ground connection.
• If 12V, check for 12v at pins at pins 2-3 on display side of connector. • If no voltage, replace wire harness. • If 12v, display is faulty. Replace display. No Communications Check for 12V at Control Module pins M1-M4, if no voltage check: • Fuse on Gator Harness • Chassis harness connection • Spreader harness connection. No Communications No CAN communication between Control Module and Display Module • Display harness connection. • Spreader harness connection.
• Check continuity from Control Module pin A2 to spreader harness pin 4 • Check continuity from Control Module pin C2 to spreader harness pin 5 Material is not flowing with the gate open • Check that the gate stop is in the correct position according to the calibration procedure and adjust if necessary • Material that has gotten damp may clump and will not flow as well as dry material. Always operate the spreader with the lid installed SPN Error Description Troubleshooting Guide 1100 High Temperature Fault Internal temperature above 75C The module will stop operating the spreader if the internal temperature rises above 75C. This is a latching fault to protect the electronics.
Reduce the module’s exposure to high temperatures to allow its internal temperature to fall below 75C. The module must be power cycled to recover from a high temperature fault. 1101 High Temperature Warning Internal temperature above 65C No action is necessary. The module will continue operating the spreader with an internal temperature between 65C and 75C but will stop operating the spreader if the internal temperature rises above 75C. 1102 Low Temperature Fault Internal temperature below -30C The module will stop operating the spreader if the internal temperature falls below -30C. This is a latching fault to protect the electronics.
Reduce the module’s exposure to low temperatures to allow its internal temperature to rise above -30C. The module must be power cycled to recover from a low temperature fault.
