SEAL 3898395 - Caterpillar

Test Step 1. Check for Connector Damage.
Turn the circuit breaker for the battery to the OFF position.
Turn the ECS to the OFF/RESET position.
Thoroughly inspect the ECM connectors J1/P1 and J2/P2. Inspect all of the other connectors. Refer to the diagnostic functional test 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 2.25 0.25 N m (20 2 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 for pinch points.Expected Result:All connectors, pins, and sockets are coupled and/or inserted. The harness and wiring should be free of corrosion, of abrasion or of pinch points.Results:
OK - The connectors and wiring are okay. Proceed to Test Step 2.
Not OK - The connectors and/or wiring need repair.Repair: Repair the connectors or wiring and/or replace the connectors or wiring.STOPTest Step 2. Check the Status of the ECS in the STOP Position.
Turn the circuit breaker for the battery to the ON position.
Connect the Cat ET to the service tool connector.
Turn the ECS to the STOP position.
Observe the status for the ECS on the Cat ET.Expected Result:The status for the ECS should read "STOP".Results:
OK - The ECS is functioning correctly. Proceed to Test Step 3.
Not OK - The status for the ECS does not display "STOP". Proceed to Test Step 4.Test Step 3. Check the Status of the ECS in the START Position.
Turn the ECS to the START position.
Observe the status for the ECS on the Cat ET.Expected Result:The status for the ECS should read "RUN".Results:
OK - The ECS is functioning correctly. Proceed to Test Step 5.
Not OK - The status of the ECS does not display "RUN". Proceed to Test Step 4.Test Step 4. Install a Jumper Wire.
Turn the ECS to the OFF/RESET position.
Disconnect the primary ECM connector P1. Remove wires P1-14, P1-8 and P1-29.
Fabricate a jumper wire.
Install the jumper wire at P1. Connect the jumper wire between P1-14 and P1-8 to P1-29. Reconnect P1.
Turn the ECS to the STOP position.
Observe the status for the ECS on the Cat ET.
Turn the ECS to the OFF/RESET position and remove the jumper wire.Expected Result:The status for the ECS should display "RUN" while the jumper wire is installed. The status for the ECS should display"STOP" when the jumper wire is removed.Results:
OK - The status for the ECS displays the proper states. The problem is not with the ECM. Proceed to Test Step 6.
Not OK - The status for the ECS does not show the correct states.Repair: Replace the ECM. Refer to the diagnostic procedure Troubleshooting, "Replacing the ECM".STOPTest Step 5. Check the Status of the ECS in the AUTO Position.
Turn the ECS to AUTO. Place the Remote START/STOP Switch in the START position.
Observe the status for the ECS on the Cat ET. Observe
