LEVER ASSEM. 5K2206 - Caterpillar

Use this procedure to troubleshoot a suspected problem with the ground level shutdown switch. Use this procedure if a diagnostic code in Table 1 is active or easily repeated.
Table 1
Diagnostic Codes Table
Description Conditions which Generate this Code System Response
E265(3) User Defined Shutdown The inputs from the ground level shutdown switch to the Electronic Control Module (ECM) have changed states. The engine will shut down. The code is logged.
267-3 Remote Shutdown Input voltage above normal Both of the switch contacts of the ground level shutdown switch are in the open state. If both of the switch contacts from the ground level shutdown switch change to the same state and the engine is running, the engine will continue to run. The code is logged.
267-4 Remote Shutdown Input voltage below normal Both of the switch contacts of the ground level shutdown switch are in the closed state. The ground level shutdown switch provides the ability to shut down the engine. The engine's ECM remains active. Caterpillar Electronic Technician (ET) can be used to communicate with the ECM. The ground level shutdown switch must be returned to the RUN position and the engine rpm must be zero before the ECM will allow the engine to start.To shut down the engine, lift the red cover guard and toggle the ground level shutdown switch to the SHUTDOWN position. The ECM reads the position of the ground level shutdown switch. If the engine is running, the ECM disables the fuel injection. The status screen will display "INJECTION DISABLED" and "REMOTE SHUTDOWN".The ECM will not allow the engine to start if the status for the ground level shutdown switch is "REMOTE SHUTDOWN".

P1 ECM connector
(P1-54) user defined shutdown (NO)
(P1-56) user defined shutdown (NC) Test Step 1. Inspect Electrical Connectors and Wiring
Turn the keyswitch to the OFF position.
Thoroughly inspect the ECM connector J1/P1. Thoroughly inspect the connectors for the ground level shutdown switch. Refer to Troubleshooting, "Electrical Connectors - Inspect" 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. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
Check the harness and the wiring for abrasion and for pinch points. Expected Result:All connectors, pins, and sockets are completely coupled and/or inserted. The harness and wiring are free of corrosion, of abrasion, and of pinch points.Results:
OK - The harness and wiring are OK. Proceed to Test Step 2.
Not OK - There is a problem in the connectors and/or wiring.Repair: Repair the connectors or wiring and/or replace the connectors or wiring. Ensure that all of the seals are properly in place and ensure that the connectors are completely coupled.Verify that the repair eliminates the problem.STOPTest Step 2. Check the Status of the Ground Level Shutdown Switch on Cat ET
Connect Cat ET to the service tool connector. Start Cat ET.
Turn the keyswitch to the ON position.
Observe the status of the ground level shutdown switch on
