Suggested Actions
- 1Warning will clear after engine runs with no DTC codes three times
- 2System detected fuel in the outer basin tank and has triggered the warning
- 3The system detected fuel in the outer basin tank and has triggered the warning.
- 4Address charging system
- 5Test 120 Volt Input (T1) page 169
- 6Power cycle controller.
- 7If problem persists, replace controller
- 8Test 29 – Emergency Stop Relay (ESR) Test page 75
- 9Reset Aux shutdown switch
- 10Review alarm log and address active alarms.
