UnclassifiedCooling

What This Code Means

O2 sensor stuck open/closed; Low fuel level; Low fuel pressure; Fuel in the outer basin tank; Battery voltage below 12.1V for greater than 60 seconds; Completed 26 hour charge cycle, battery voltage below 12.52V, or current draw from charger still greater than 600 mA; Battery voltage above 16.1V; AC input to battery charger missing for greater than five minutes during charging; Controller wrote to the EEPROM more than 500 times in less than four minutes; Air/fuel mix is too rich for more than 10s; Air/fuel mix is too lean for more than 60s; Low Fuel Level; Low Fuel Pressure; High fuel level warning; Warning on a configured IO Extender Digital Input; Low coolant detected; High oil temperature; Low oil level; Check Engine warning (emissions certified gas units); Active Fault

Possible Causes

  • •DTC logged in eeprom
  • •Fuel level above 10% but lower than 20% for greater than 60 seconds
  • •Low fuel pressure detected for greater than 60 seconds
  • •Ruptured tank
  • •Low battery
  • •Battery Problem
  • •Charger Warning
  • •Charger Missing AC
  • •EEPROM Abuse
  • •Gaseous Emissions
  • •Ruptured Tank
  • •Fuel pressure falls below 5.2 in H2O +/- 0.4 in (below 0.19 psi)
  • •Fuel level rises above the dealer adjustable setpoint (0-99%) for 1 second
  • •Digital Input status triggered the alarm
  • •Low coolant digital input detected low coolant for greater than 5 seconds
  • •Oil temperature is > 320 °F (160 °C) while the engine is running
  • •Oil level is below limit, detected after a 60 sec hold-off since startup
  • •O2 sensor exists and is faulted (O2 sensor stuck open/closed) for 90 seconds
  • •ECODE

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. 4Refer to 'Problem 34 – Low Fuel Pressure' page 141
  5. 5Check Fuel Level
  6. 6Review alarm log and address active alarms
  7. 7Refer to 'Problem 26 – Low Coolant Level' page 138
  8. 8Refer to 'Test 115 – Oil Temperature Sensor (OTS) Resistance' page 179
  9. 9Refer to 'Problem 28 – Low/High Oil Pressure' page 138
  10. 10Engine runs with no O2 sensor faults (stuck open/closed) for 4 minutes to clear warning
