Schematic diagram of the circuit for ignition shutdownThe engine is not equipped with a remote control panel.Test Step 1. Inspect the Electrical Connectors and the Wiring
Set the engine control to the OFF/RESET mode. Remove the electrical power from the engine.Note: For the following steps, refer to Troubleshooting, "Inspecting Electrical Connectors".
Thoroughly inspect each of the following connectors:
EIS connectors for the EIS control module
Connections for each emergency stop switch
Connections on the back of the SCM (if equipped)
Shutdown relays and/or switches that are provided by the customer
Illustration 5 g01045997
Harness side of the EIS connector (EISC-B) −Battery (EISC-L) Input for ignition shutdown
Perform a 45 N (10 lb) pull test on each of the wires that are associated with the circuit for the ignition shutdown.
Check the terminal strips for corrosion and for mechanical failure.
If the engine is equipped for CSA, check the harnesses and the wiring for abrasion and for pinch points between the device that requests ignition shutdown and the EIS control module.Expected Result:The connectors, pins, and sockets are connected properly. The terminal strips do not have corrosion or mechanical failure. The connectors and the wiring do not have corrosion, abrasion, or pinch points.Results:
OK - The components are in good condition with proper connections. Proceed to Test Step 2.
Not OK - The components are not in good condition and/or at least one connection is improper.Repair: Perform the necessary repairs and/or replace parts, if necessary.STOPTest Step 2. Check the Wiring for an Open Circuit
Disconnect the EIS connectors.
Verify that all of the emergency stop buttons are set for normal operation.
If the engine is equipped with a SCM, measure the resistance between EISC-L and terminal 24 on the SCM. Otherwise, measure the resistance between EISC-L and the device that opens the circuit for terminating the ignition.
If the engine is equipped with EMCP II, measure the resistance between terminals 44 and 30 on the 70 pin connector.Expected Result:Each check of the resistance is less than 2 Ohms.Results:
OK - Each check of the resistance is less than 2 Ohms. The wiring does not have an open circuit. Proceed to Test Step 3.
Not OK - At least one check of the resistance is greater than 2 Ohms. The wiring has an open circuit.Repair: Repair the connection and/or the wire, when possible. Replace parts, if necessary. Verify that the problem is resolved.STOPTest Step 3. Check the Wiring for a Short Circuit
Disconnect wire M200-BK from terminal 24 on the SCM (if equipped). Otherwise, disconnect the wire from the device that opens the circuit for terminating the ignition.
Measure the resistance between terminals EISC-L and EISC-B.
If the engine is equipped with EMCP II, disconnect terminals 44 and 30 on the 70 pin connector.
Measure the resistance between terminals 44 and 30.Expected Result:The resistance is greater than 2 Ohms.Results:
OK - The resistance is greater than 2 Ohms. The wiring does not have a short circuit. Proceed to Test Step 4.
Not OK - The resistance is less than 2 Ohms. The wiring has a short circuit.Repair: Repair the connection and/or the wire, when possible. Replace parts, if necessary. Verify that the problem is resolved.STOPTest Step 4. Check the Operation of the Circuit for Ignition Shutdown
Reconnect all of connectors and the wiring.
Restore the electrical power to the engine.
Start the engine.
Set the engine control to the "OFF/RESET" mode.Expected Result:The engine shuts down. A 331-11 code is not generated.Results:
OK - The engine shut down. A 331-11 code is not generated.STOP
Not OK - The engine did not shut down properly or there is a 331-11 diagnostic code.Repair: If the engine is equipped with the optional SCM, check the operation of the SCM. Refer to Testing and Adjusting, SENR6420.If the command for the ignition shutdown is provided by the customer's equipment, test the equipment according to the appropriate literature. Verify that the customer's equipment is operating correctly. If the problem is not resolved, proceed to Test Step 5.Test Step 5. Perform a Self Test of the EIS Control Module
Perform the self test for the EIS control module. Refer to Troubleshooting, "Control Module Self Test".Expected Result:The self test was successful.Results:
OK - The self test was successful.Repair: If the problem persists, refer to Troubleshooting, "Inspecting Electrical Connectors".STOP
Not OK - The self test was not successful.Repair: Perform the corrective action that is appropriate for the fault. Refer to Troubleshooting, "Control Module Self T
