Information:
System Operation Description:Use this procedure under the following situation:The engine running output circuit is suspected of incorrect operation.The following background information is related to this procedure:Engine Running OutputThe "Engine Running Output" can be programmed to J1/P1-28, J1/P1-34, or J1/P1-40. The "Engine Running Output" will function on the following corresponding output that is selected:
ECM Connector J1/P1-28
ECM Connector J1/P1-34
ECM Connector J1/P1-40
Illustration 1 g01064548
The "Engine Running Output" activates when the engine is running. This can be used to prevent the engagement of the starting motor while the engine is running. The Engine Control Module (ECM) can be connected to a relay that disables the starter. The relay is normally closed so cranking can be achieved immediately at powerup. During cranking, the ECM energizes the "Engine Running Output" once engine rpm reaches 50 rpm below low idle. The output is de-energized when the engine speed falls by 100 rpm below the programmed low idle. The low idle rpm is programmable. The range for low idle is between 600 rpm and 750 rpm.

Terminal locations at the ECMTest Step 1. Inspect the Electrical Connectors and the Wiring
Thoroughly inspect ECM vehicle harness connector J1/P1, and the firewall bulkhead connector. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
Perform a 45 N (10 lb) pull test on terminal 28, terminal 34, or terminal 40 in the ECM connector.Refer to Illustration 3.
Check the allen head screws at each of the ECM connectors for the proper torque. Refer to Troubleshooting, "Electrical Connectors - Inspect" for the correct torque value.
Check the harness and wiring for abrasion and for pinch points from the sensor to the ECM.Expected Result:All connectors, pins and sockets are completely coupled and/or inserted and the harness and wiring should be free of corrosion, of abrasion or of pinch points.Results:
OK - Proceed to Test Step 2.
Not OK - Repair the wiring or replace the wiring, if necessary. Repair the connectors or replace the connectors, if necessary. Ensure that all of the seals are in the proper place. Ensure that all of the connectors are connected properly. Verify that the repair eliminates the problem.STOPTest Step 2. Check the Configuration Parameters
Connect the Caterpillar Electronic Technician (ET) to the cab data link connector.
Turn the keyswitch to the ON position.
Access the "Customer Specified Parameter Screen" in order to make sure that the ECM is programmed to use the "Engine Running Output".
Ensure that the "Engine Running Output" circuit is connected to the programmed output.Expected Result:The circuit is connected to the correct ECM terminal that is selected for the "Engine Running Output".Results:
OK - Proceed to Test Step 3.
Not OK - Update the customer specified parameter in order to match the correct output terminal.STOPTest Step 3. Use Cat ET Check for an Audible Click at the Relay
Turn the keyswitch to the ON position.
Access the "Engine Running Output Special Test" on ET. The "Engine Running Output Special Test" will enable the "Engine Running Output" when the test is active.
Begin the "Engine Running Output Special Test" and listen for the
