Diagnostic Trouble Codes    
CDL Code    J1939 Code    Description    Comments    
E1026 (1)     3474-14     Aftertreatment #1 Loss of Combustion     The Aftertreatment Regeneration Device (ARD) has stopped generating heat at least four times during an active high speed regeneration.
Associated codes may indicate the system that caused the loss of combustion to occur.
The code must be cleared with the "Reset All" button on the active diagnostics screen in Caterpillar Electronic Technician (ET). If an active regeneration is initiated with the operator forced regeneration switch, the Engine Control Module (ECM) clears this code automatically.    
E1026 (2)     3474-31     Aftertreatment #1 Loss of Combustion     The ARD has stopped generating heat at least four times during an active regeneration.
Associated codes may indicate the system that caused the loss of combustion to occur.
The code must be cleared with the "Reset All" button on the active diagnostics screen in Cat ET. If an active regeneration is initiated with the operator forced regeneration switch, the ECM clears this code automatically.    
Follow the troubleshooting procedure in order to identify the root cause of the problem.    System OperationThe combustion air system routes pressurized air from the outlet of the turbocharger compressor to the ARD. The combustion air is mixed with fuel inside the ARD. The air/fuel mixture is ignited and the air/fuel mixture is burned in order to provide heat for the diesel particulate filter.Illustration 3 and Illustration 3 show the location of the components for the combustion air system.

The ECM uses the signal to determine the amount of combustion air that is flowing to the ARD combustion head.The ECM creates a pulse width modulated signal that specifies the amount of combustion air that is desired. The ECM sends the signal to the control group.The actuator for the combustion air receives the PWM signal from the ECM. The actuator for the combustion air moves a spool in the air pressure control valve. The combustion air valve regulates the combustion air to the ARD head.

Troubleshooting Test Steps    Values    Results    
1. Check for Associated Diagnostic Trouble Codes
A. Establish communication between Cat® ET and the Electronic Control Module (ECM). Refer to Troubleshooting, "Electronic Service Tools", if necessary.
B. Download the "Warranty Report" from the engine ECM before performing any troubleshooting or clearing diagnostic trouble codes.
C. If troubleshooting a 1026 or a 3474 code, access the Aftertreatment Regeneration History in Cat ET. Click on the information tab, then click History, and then click Aftertreatment Regeneration History. If there were three successful regenerations since the code was logged, do not troubleshoot this code. Clear the code and return the unit to service.
Table 2 lists the diagnostic trouble codes that are associated with a E1026 code. Determine if any of the codes in Table 2 are present.
   
Diagnostic Code
   
Result: An associated diagnostic trouble code is not present.
Proceed to Test Step 2.
Result: An associated diagnostic trouble code is present.
Repair: Refer to Troubleshooting, "Diagnostic Trouble Codes" in order to troubleshoot the associated diagnostic code.
   
2. Check the Current Flow Through the Heater
A. Verify that the engine is off. Check the current flow through the heater. Refer to Systems Operation/Testing and Adjusting, "ARD Nozzle Heater - Test" for the correct procedure.
   
Between 7.0 A and 14 A for a 12 V System. Or, Between 3.5 A and 7 A for a 24 V System
   
The current flow is between 7.0 A and 14 A for a 12 V system. Or, the current flow is between 3.5 A and 7 A for a 24 V system.
Result: The current flow is OK.
Proceed to Test Step 3.
Result: The current flow is not between 7.0 A and 14 A for a 12 V system. Or, the current flow is not between 3.5 A and 7 A for a 24 V system.
Repair: There may be a problem with the ARD nozzle. Refer to Troubleshooting, "ARD Nozzle - Test".
   
3. Perform the "ARD Air System Service Test"
A. Reset all active codes and clear all logged codes. Use Cat ET to perform an "ARD Air System Service Test" in order to verify that the problem is resolved. Refer to Troubleshooting, "ARD Combustion Air - Test".
   
ARD Air System Service Test
   
Result: The "ARD Air System Service Test" failed.
