61 Ford generator fault/alarm codes with symptom, cause and remedy — compiled from Ford service and controller documentation.
| Code | Meaning / symptom | Cause | Remedy |
|---|---|---|---|
| 4 | Platform in contact with live power lines and operator incapacitated | Contact authorized personnel to disconnect power supply from unit. Have someone summon first aid or rescue squad. If operator is unconscious, check if he is in a pinned position, or would be endangered if platform is moved. AFTER POWER IS CUT, use the emergency lowering procedure to bring platform with operator to a safe location to render first aid. | |

| FAULT 1 | The FAULT 1 or FAULT 2 fault lamp lights. Engine shuts down immediately, engine runs for several seconds and then shuts down, or engine continues to run | The standard undesignated fault functions are programmed to shut down the set when a fault is sensed. Fault 1 is time delayed while Fault 2 is immediate. The nature of the fault is an optional selection that is determined when the set installation is designed. The undesignated fault functions may also be programmed for non-shutdown or non-time delay. | |
| FAULT 1 or FAULT 2 | Engine shuts down immediately, engine runs for several seconds and then shuts down, or engine continues to run. | ||
| FAULT 2 | The FAULT 1 or FAULT 2 fault lamp lights. Engine shuts down immediately, engine runs for several seconds and then shuts down, or engine continues to run | The standard undesignated fault functions are programmed to shut down the set when a fault is sensed. Fault 1 is time delayed while Fault 2 is immediate. The nature of the fault is an optional selection that is determined when the set installation is designed. The undesignated fault functions may also be programmed for non-shutdown or non-time delay. | |
| HI ENG TEMP | HI ENG TEMP lamp lights. Engine shuts down. | Indicates engine has overheated (engine temperature has risen above 215° F/102° C) or coolant level is low (sets with coolant level sensor). Allow engine to cool down completely before proceeding with the following checks: a. Check coolant level and replenish if low. Look for possible coolant leakage points and repair if necessary. b. Check for obstructions to cooling airflow and correct as necessary. c. Check for a slipping fan belt and tighten if loose. d. Reset control and restart after locating and correcting problem. Contact an authorized service center if none of the above. | |
| LO FUEL | LO FUEL lamp lights. Engine continues to run. | Indicates gasoline fuel supply is running low. Check fuel supply and replenish as required. | |
| LO FUEL LAMP | LO FUEL LAMP lights. Engine shuts down and LO OIL PRES lamp lights. | Indicates engine has run out of fuel. Check fuel level and replenish as required. | |
| LO OIL PRES | LO OIL PRES lamp lights. Engine shuts down. | Indicates engine oil pressure has dropped to 25 psi (172 kPa). Check oil level and filters. If oil system is OK but oil level is low, replenish. Reset control and restart. Contact an authorized service center if oil pressure is not in the range of 40 to 65psi (275 to 448 kPa). | |
| LOW FUEL | Engine continues to run or is in standby mode. | Indicates fuel supply pressure is marginally low (5 inches [127 mm] WC or less). Check for partially closed shutoff valve, empty propane supply tank. For natural gas fueled sets, check with the gas utility. | |
| PRE HI ENGINE TEMP | PRE HI ENGINE TEMP lamp lights. Engine continues to operate. | Indicates engine has begun to overheat and engine temperature has risen to approximately 205° F (97° C). If generator is powering non-critical and critical loads and cannot be shut down, use the following: a. Reduce load if possible by turning off non-critical loads. b. Check air inlets and outlets and remove any obstructions to airflow. If engine can be stopped, follow procedure in step 3. | |
| PRE LO OIL PRES | PRE LO OIL PRES lamp lights. Engine continues to operate. | Indicates engine oil pressure has dropped to 30 psi (207 kPa). If generator is powering critical loads and cannot be shut down, wait until next shutdown period and then follow step 5 procedure. If engine can be stopped, follow procedures in step 5. | |
