Hi

Try to do and check one of the posibilities below:
- Canbus system : R between Can L and H = 60 Ohm, Canbus power supply = 24 VDC/ 12 VDC, Voltage Can H and GND ~ 2.7VDC, and Can L and GND ~ 2.3VDC; Can H and Can L must be insulated from the GND system.
- Either FPS or Travel/Pump power module is defective or no power supply.
Hope it help
