Schematic For An Unexpected ShutdownThe CID 330 alerts the operator that the GSC did not control the engine shutdown. The GSC normally controls all engine shutdowns. If an outside influence causes the engine to shut down, the GSC indicates a CID 330. There is only one failure mode for a CID 330 and the mode is FMI 7 (faulty mechanical response).The diagnostic code causes the following sequence of events:
On a running engine, the GSC detects that the engine speed has dropped from the rated speed to 0 rpm when the GSC has not called for a shutdown.
The GSC determines that no fault for the engine speed sensor is present that explains the drop in the speed signal.
The GSC indicates a CID 330 FMI 7 and the GSC disables the engine from running. Note: An unexpected shutdown fault will initiate a signal from the shunt trip circuit breaker. Note: Diagnostic codes are created when the harness connector (40 contact) is disconnected from the GSC during these troubleshooting procedures. Clear these created diagnostic codes after the particular fault is corrected. In a properly operating system, when the harness connector is removed from the GSC, the following diagnostic codes are recorded.
CID 100 FMI 3 pressure sensor (engine oil)
CID 110 FMI 3 temperature sensor (engine coolant)
CID 111 FMI 3 fluid level sensor (engine coolant)
CID 190 FMI 3 speed sensor (engine)
CID 331 FMI 2 switch (engine control)
CID 336 FMI 2 switch (engine control)ProcedureThe following condition is a possible cause of a CID 330 FMI 7:
A component that is not under the control of the GSC has caused an engine shutdown.The GSC treats this diagnostic code as a shutdown fault. Clear the diagnostic code from the fault log after troubleshooting is complete. Note: This procedure requires many voltage measurements during simulated engine cranking. The fuse for the starting motor "F4" on the relay module is removed in order to prevent the activation of the starting motor. Voltage measurements must be made quickly before the total cycle crank time (setpoint P17) elapses. The total cycle crank time has been defaulted to ninety seconds. See Systems Operation, "Engine/Generator Programming OP5". If a voltage measurement takes too long (more than 90 seconds), the GSC indicates an overcrank fault. The indicator for the overcrank shutdown will FLASH. In order to continue with a voltage measurement, the overcrank fault must be reset by turning the ECS to OFF/RESET. Then turn the ECS to START.
Perform an initial check. Before proceeding with the troubleshooting procedures, do the following steps:
Make sure that there are NO OTHER ACTIVE FAULTS. Erroneous troubleshooting and needless replacement of parts can be caused by a failure to check for other diagnostic codes. The operator will make many voltage measurements while the GSC is attempting to crank the engine. The GSC detects other diagnostic codes. If the GSC detects other diagnostic codes, the GSC will prevent the starting of the engine by sending a signal to the PEEC electronic control module. This signal will turn off the fuel shutoff solenoid and this signal will shut down the engine.
Check the fuel level and the fuel quality.
Check for a plugged fuel filter.
Check for a plugged air filter.
Refer to the Engine Service Manual if there is an obvious engine fault. Also, refer to the Engine Service Manual if there is an obvious fault with the fuel system.
Check the engine speed sensor for the PEEC electronic control module.
Check the air shutoff solenoid for activation. If the air shutoff solenoid is activated and the air shutoff solenoid cannot be deactivated, begin troubleshooting with 17. Otherwise begin troubleshooting with 2.
Verify the diagnostic code.
Observe the upper display. Check that the CID 330 FMI 7 is showing.Expected Result: A CID 330 FMI 7 is showing as an active fault.Results:
No - A CID 330 FMI 7 is NOT showing. No active CID 330 FMI 7 exists. STOP.
Yes - Only a CID 330 FMI 7 is showing. Proceed to 3. (If an inactive CID 330 FMI 7 is showing in the fault log, check the history of the genset and proceed to 3.)
Check the system voltage.
Ensure that the engine is off. Measure the system voltage at the battery. Make a note of this measurement. The measurement for the system voltage is used for comparison in future steps of this procedure.Expected Result: For 24 volt systems, the system voltage should be from 24.8 to 29.5 DCV. For 32 volt systems, the system voltage should be from 33.1 to 39.3 DCV.Results:
OK - Proceed to 4.
NOT OK - System voltage is NOT correct. For troubleshooting, see the procedure for system voltage. STOP.
Check the setpoint P01. PEEC engines have ETR systems.
Check the setpoint P01 for proper programming ("0" for ETR). See Systems Operation, "Setpoint Viewing OP2".Expected Result: Setpoint P01 should be programmed to "0" for ETR.Results:
OK - Proceed to 5.
Not OK - Setpoint P01 is NOT programmed correctly. Reprogram setpoint P01. See Systems Operation, "Engine/Generator Programming OP5".
Check the fuses.
Turn the ECS to OFF/RESET.
Check fuse "F10" on the relay module.Expected Result: Fuse "F10" should not be blown. Results:
OK - Proceed to 7.
NOT OK - One or more of the fuses are blown. Proceed to 6.
Troubleshoot the blown fuse.For reference, see the preceding System Schematics and Testing And Adjusting, "Schematics and Wiring Diagrams".
The ECS remains in the OFF/RESET position.
Remove the fuse that is blown.
Measure the resistance from RM-39 of the relay module to ground (B-).Expected Result: The resistance of the circuit should be less than 3 ohms for the circuit with the fuse that is blown.Results:
OK - Resistance is greater than 3 ohms and fuse is no longer blowing. Carefully check ALL wires that are connected to the appropriate terminal of the relay module for abrasion or worn spots in the insulation that could be causing the short. Check the wires in the panel and the generator panel. Also check the wires on the engine harness. Refer to the various wiring diagrams. Repair the wiring or replace wiring, if necessary. STOP.
NOT OK - If a resistance is less than 3 ohms, there is
