J1939 Code and Description CDL Code and Description Comments
4215-3
Ground-Level Shutdown Activated : Voltage Above Normal 267-3
Remote Shutdown Input : Voltage Above Normal If both 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.
4215-4
Ground-Level Shutdown Activated : Voltage Below Normal 267-4
Remote Shutdown Input : Voltage Below Normal If both 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.
4215-31
Ground-Level Shutdown Activated E678 (1)
Ground Level Shutdown The inputs from the ground level shutdown switch to the ECM have changed states.
The engine will shutdown. The code is logged. The shutdown switch will shutdown the engine. The A6:E2 ECM remains active. Cat® Electronic Technician (ET) can be used to communicate with the ECM. The shutdown switch must be returned to the RUN position before the ECM will allow the engine to start.The ECM reads the position of the shutdown switch. If the engine is running, the ECM disables the fuel injection. The status screen will display"Injection Disabled" and "Remote Shutdown".

Troubleshooting Test Steps Values Results
1. Check for Codes
A. Establish communication between Cat ET and the ECM . Refer to Troubleshooting, "Electronic Service Tools", if necessary.
B. Observe the "Active Diagnostic" screen on Cat ET. Wait at least 30 seconds so that any codes may become active.
C. Look for a code from the table above.
Codes
Result: A E678 or 4215-31 diagnostic code is active.
Proceed to Test Step 2.
Result: A 267-3 or 4215-3 diagnostic code is active.
Proceed to Test Step 3.
Result: A 267-4 or 4215-4 diagnostic code is active.
Proceed to Test Step 4.
2. Check the "Status" of the Shutdown Switch on Cat ET
A. Activate the shutdown.
B. Use Cat ET to verify that the engine rpm is 0. Return the shutdown switch to the RUN position.
C. Use Cat ET to observe the status of the shutdown switch.
Switch Status
Result: The status of the shutdown switch changed states after returning the shutdown switch to the RUN position.
The shutdown switch is operating correctly. Return to service.
Result: The status of the shutdown switch does not change states after returning the shutdown switch to the RUN position.
Proceed to Test Step 3.
3. Create a Short at the Connector for the Shutdown Switch
A. Turn the keyswitch to OFF.
B. Disconnect the connector for the shutdown switch.
C. Create a short circuit at the connector for the shutdown switch between terminal 1 and terminal 2.
D. Turn the keyswitch to ON.
E. Use Cat ET to observe the "Status" of the shutdown switch.
F. Remove the wire short.
Short Circuit
Result: The status of the shutdown switch changed states after creating the short circuit.
Repair: Install a new shutdown switch. Verify that the problem is resolved.
Result:The status of the shutdown switch did not change states after creating the short circuit.
Repair: Repair the wiring or replace the harness. Use Cat ET to verify that the problem is resolved.
4. Create an Open at the Connector for the Shutdown Switch
A. Turn the keyswitch to OFF.
B. Disconnect the connector for the shutdown switch.
C. Turn the keyswitch to ON.
D. Use Cat ET to observe the "Status" of the shutdown switch.
Open Circuit
Result: The status of the shutdown switch changed states after creating the open circuit.
Repair: Install a new shutdown switch. Use Cat ET to verify that the problem is resolved.
Result: The status of the shutdown switch did not change states after creating the open circuit.
Repair: Repair the harness or replace the harness. Use Cat ET to verify that the problem is resolved.
If the procedure did not correct the issue, contact your Cat dealer Technical Communicator (TC). For further assistance, your TC can confer with the Dealer Solutions Network (DSN).
