Table 1
Diagnostic Codes Table    
Description     Conditions which Generate this Code     System Response    
267-2 Remote Shutdown Input erratic, intermittent, or incorrect     The Electronic Control Module (ECM) detects that both of the switch inputs are open or that both of the switch inputs are closed.     The code is logged.
If equipped, the warning light will illuminate.
The engine will shut down.
If the engine is not running, the engine will start.    The engine shutdown switch allows the operator to shut down the engine from outside of the cab at ground level. When the switch is toggled to the STOP position, the engine shuts down. The ECM remains powered. The engine shutdown switch must be returned to the RUN position and the electrical power to the ECM must be cycled before the engine will be allowed to start.

Remove the electrical power from the ECM.
Thoroughly inspect the J1/P1 ECM connectors and the connectors for the engine shutdown switch. Refer to service Troubleshooting, "Electrical Connectors - Inspect".
Perform a 45 N (10 lb) pull test on each of the wires for the engine shutdown switch.
Check the torque of the allen head screw on the ECM connectors. Refer to service Troubleshooting, "Electrical Connectors - Inspect".
Check the harness and the wiring for abrasion and for pinch points from the switch back to the ECM.Expected Result:All of the connectors, pins and sockets are completely coupled and/or inserted and the harness and wiring are free of corrosion, of abrasion and of pinch points.Results:
OK - The harness and the connectors appear to be OK. Proceed to Test Step 2.
Not OK - There is a problem with the connectors and/or wiring.Repair: Repair the wiring and/or the connectors. Replace parts, if necessary. Ensure that all of the seals are properly in place and ensure that the connectors are completely coupled.If applicable, use Caterpillar Electronic Technician (ET) to perform a "Wiggle Test".Use Cat ET in order
