Engine Events
J1939 Code and Description Conditions which Activate the Code System Response
1664-31
Engine Automatic Start Failed A starting attempt has exceeded the time that is programmed for the "Crank Duration" parameter. The code is logged.
The red stop lamp is illuminated.
The engine is shut down.(1)
(1) Activation of this code latches an engine shutdown condition. The power to the ECM must be cycled prior to any additional attempts to start the engine.Probable Causes
Fuel supply
Electrical connectors or power supply
Engine speed/timing sensor
Ignition system
Incorrect engine timing
Excessive loadRecommended Repairs
Fuel Supply
Ensure that fuel is supplied at a sufficient pressure that is stable. Ensure that the size of the fuel line is sufficient to provide the engine with the correct volume of fuel. Inspect the fuel system for leaks.The following conditions can cause a problem with the engine operation:
Low fuel pressure
High fuel pressure
Poor fuel qualityEnsure that the fuel pressure is correct. When possible, interview the operator to determine if fuel quality is in question. Try to determine if the source of the fuel was changed.Inspect the fuel system components: fuel filter, gas pressure regulator, gas shutoff valve, and fuel actuator. Verify that the system components are operating correctly.Replace the fuel filter, if necessary.Electrical Connectors or Power Supply
There may be an intermittent interruption of power. Check the wiring harnesses and the connectors. Inspect the connectors in the terminal box. Inspect the power supply connections and the ground.Inspect the wiring from the power supply to the ECM. Check the power and ground connections. Refer to Troubleshooting, "Electrical Power Supply - Test".Speed/Timing Sensor
Visually inspect the engine speed/timing sensor. Ensure that the sensor is installed correctly. Use Cat ET to check for a diagnostic code that is related to the engine speed/timing sensor. Refer to Troubleshooting, "Speed/Timing - Test".Ignition System
Inspect the ignition system for the following conditions:
Check the connections between the ignition transformers and the spark plug wires. A loose connection can cause arcing and misfires.
Check that the correct transformers and spark plugs are installed for your engine. Inspect the extenders for signs of pin holes and of electrical arcing. Check the spark plugs for fouling, correct gap adjustment, and moisture.
Check for corrosion on the terminal of the spark plug and check for wear on the electrode. Both conditions can cause misfires.Losses or misfires are caused by shorts or excessive moisture.Maintain the spark plug gap according to the Operation and Maintenance Manual.Incorrect Engine Timing
Verify that the base timing is correct. The base timing is calibrated by the Electronic Control Module (ECM) automatically during each engine startup. For additional information, refer to Troubleshooting, "Speed/Timing" for details.Verify that the engine timing is correct. Ensure that the “First Desired Timing” parameter is correct. Refer to Systems Operation/Testing and Adjusting, "System Configuration Parameters" for information related to these parameters.Excessive Load
Ensure that the load is not excessive. Reduce the load. If necessary, disengage the driven equipment and test the engine.
