Suggested Actions

  1. 1Warning will clear after engine runs with no DTC codes three times
  2. 2System detected fuel in the outer basin tank and has triggered the warning
  3. 3The system detected fuel in the outer basin tank and has triggered the warning.
  4. 4Test 68 – Check Actuator and Mixer Function page 163
  5. 5Test 106 – Test CAN bus Communication page 174
  6. 6Confirm battery type settings
  7. 7Inspect RS-485 wiring/terminating jumper on I/O
  8. 8Confirm external charger settings on controller menu
  9. 9Check external battery charger
  10. 10Check Fuel Level
