SHIM 8X0369 - Caterpillar

System Operation Description:The ECM receives a signal from the Emergency Stop Switch. The ECM will shut down the engine when the signal is open. Refer to the Electrical Schematic.When an Emergency Stop signal is received, the fuel supply is cut off. The customer can install multiple emergency stop switches. When the Start/Run/Stop switch is active, the engine will begin the start-up cycle. When the emergency stop switch is active, the engine will not run. The ECM will also trigger the Air Shutoff.

Note: The following process must be followed if one or more emergency stop switches are present in the circuit.Test Step 1. Check the Electrical Connectors and the Wiring.
Turn the Battery switch for the ECM to the OFF position.
Turn the breaker at the battery to the OFF position.
Thoroughly inspect the ECM connector J1/P1. Inspect all of the other connectors. Refer to Troubleshooting, "Inspecting Electrical Connectors" for details.
Perform a 45 N (10 lb) pull test on each of the wires in the ECM connector that are associated with the circuit.
Check the ECM connector (allen head screw) for the proper torque of 6.0 N m (55 lb in).
Check the customer connector (allen head screw) for the proper torque of 2.25 0.25 N m (20 2 lb in).
Check the harness and the wiring for abrasion and pinch points.Expected Result:All connectors, pins, and sockets are completely coupled and/or inserted, and the harness and wiring should be free of corrosion, abrasion or pinch points.Results:
OK - The wiring and connectors are okay. Proceed to Test Step 2.
Not OK - Repair the wiring and connectors or replace the wiring or the connectors. Ensure that all of the seals are properly connected. Verify that the repair eliminates the problem.STOPTest Step 2. Check the Status while the Emergency Stop Switch is Activated.
Connect an Electronic Service Tool to the service tool connector.
Turn the breaker at the battery to the ON position.
Turn the Battery switch for the ECM to the ON position.
Activate the emergency stop switch.
Observe the status of the emergency stop switch on the Electronic Service Tool.Expected Result:The parameter for the emergency stop switch should read "ON".Results:
OK - The parameter for the emergency stop switch reads "ON". Proceed to test step 3.
Not OK - The parameter for the emergency stop switch does not read "ON". Proceed to test step 4.Test Step 3. Check the Status while the Emergency Stop Switch is Not Activated.
Deactivate the emergency stop switch.
Observe the status of the emergency stop switch on the Electronic Service Tool.Expected Result:The parameter for the emergency stop switch should read "OFF".Results:
OK - The parameter for the emergency stop switch reads "OFF". The emergency stop switch is functioning correctly.STOP
Not OK - The parameter for the emergency stop switch does not display "OFF". Proceed to test step 4.Test Step 4. Check the Emergency Stop Input to the ECM.
Turn the Battery switch for the ECM to the OFF position.
Disconnect ECM connector J1/P1.
Install a 40-pin Breakout T between the ECM connectors, P1, and J1.
Remove the wire F717-YL from pin 14 of
