Diagnostic Code Table    
Description    Conditions which Generate this Code    System Response    
267-2 Remote Shutdown Input erratic, intermittent, or incorrect     Both of the switch contacts for the shutdown switch are in the open state or both of the switch contacts for the shutdown switch are in the closed state.     If both of the switch contacts from the shutdown switch change to the same state and the engine is running, the engine will continue to run. The code is logged.    Determine if the shutdown was intentional or accidental. If the shutdown was intentional, make sure that the reason for the shutdown has been corrected. Reset the control system. Resume normal operation.The shutdown switch provides the ability to shut down the engine. The engine's Electronic Control Module (ECM) remains active. Caterpillar Electronic Technician (ET) can be used to communicate with the ECM. The 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 shutdown switch to the Shutdown position. The ECM reads the position of the shutdown switch. If the engine is running, the ECM disables the fuel injection.The ECM will not allow the engine to start if the status for the shutdown switch is "Remote Shutdown". Also, the keyswitch must be cycled before the ECM will allow the engine to start.

Typical schematicTest Step 1. Inspect Electrical Connectors and Wiring
Turn the keyswitch to the OFF position.
Remove electrical power from the ECM.
Illustration 2 g01139425
ECM (1) J1/P1 connectors (2) J2/P2 connectors
Thoroughly inspect the ECM connector J1/P1. Thoroughly inspect the connectors for the shutdown switch. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.

P1 ECM connector (P1-24) Shutdown (NC) (P1-25) Shutdown (NO)
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 allen head screw from each ECM connector 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 Shutdown Switch on Cat ET
Connect Cat ET to the service tool connector.
Restore electrical power to the ECM.
Turn the keyswitch to the ON position.
Observe the status of the shutdown switch on Cat ET.
Operate the shutdown switch. Observe the status of the shutdown switch on Cat ET.Expected Result:The status of the shutdown switch on Cat
