Aftertreatment #1 Loss of Combustion : Special Instruction E1026 (1)
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.
3474-31
Aftertreatment #1 Loss of Combustion E1026 (2)
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® Electronic Technician (ET). If an active regeneration is initiated with the operator forced regeneration switch, the ECM clears this code automatically.

Troubleshooting Test Steps Values Results
1. Check for Associated 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 ECM before performing any troubleshooting or clearing diagnostic trouble codes.
C. If troubleshooting a E1026 or a 3474 code, access the Aftertreatment Regeneration History in Cat ET. Click 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.
Note: Table 2 lists the codes that are associated with a E1026 code. Determine if any of the codes in Table 2 are present.
Codes
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" 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 (Current) - Test" for the correct procedure.
Between 7.0 A and 14 A for a 12 V system
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 Heater - 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" to verify that the problem is resolved.
ARD Air System Service Test
Result: The "ARD Air System Service Test" passed.
Proceed to Test Step 4.
Result: The "ARD Air System Service Test" failed.
Repair: There is a problem with the ARD combustion air system. Refer to Troubleshooting, "ARD Combustion Air - Test".
4. Clean the Flame Detection Temperature Sensor
A. Remove flame detection temperature sensor (2).
B. Clean the flame detection temperature sensor. Use a nonmetallic cleaning pad to clean the sensor.
Flame Detection Temperature Sensor
Result: The components are clean. The flame detection temperature sensor is not damaged.
Repair: Install the flame detection sensor.
Proceed to Test Step 5.
Result: The flame detection temperature is damaged.
Repair: Replace flame detection temperature sensor.
Proceed to Test Step 5.
5. Check the ARD for Proper Operation
A. Reset all active codes and clear all logged codes. Use Cat ET to perform an "ARD Ignition Test" to verify that the problem is resolved.
The ARD Ignition Test cannot be performed if the DPF soot loading is above 80%. When the DPF soot loading is above 80%, the Manual DPF Regeneration must be performed using Cat ET.
ARD Ignition Test
Result: The test is successful.
Proceed to Test Step 7.
Result: The test is not successful.
Proceed to Test Step 6.
6. Inspect ARD Swirl Plate
A. Remove ARD head. Refer to Disassembly and Assembly, "Combustion Head Group (ARD) - Remove and Install - Clean Emissions Module" for the proper procedure to remove the ARD combustion head.
Soot accumulation is normal. Slot fouling is defined as more than 1/2 the inner row slots being blocked. Partially blocked inner row slots are normal and do not affect regeneration performance.
B. Inspect the swirl plate for fouled slots.
Swirl Plate
Result: The swirl plate is fouled.
Repair: Clean the swirl plate. Refer to Testing and Adjusting, "Swirl Plate (ARD Combustion) - Inspect/Clean".
Reset all active codes and clear all logged codes. Perform the "ARD Ignition Test" in Cat ET and verify that there are no fuel leaks.
The ARD Ignition Test cannot be performed if the DPF soot loading is above 80%. When the DPF soot loading is above 80%, the Manual DPF Regeneration must be performed using Cat ET.
Proceed to Test Step 7.
Result: The swirl plate is not fouled.
Repair: Replace the ARD combustion head. Refer to Special Instruction, REHS4824, "Replacement of the ARD Combustion Head on Caterpillar Products with Clean Emissions Modules".
Reset all active codes and clear all logged codes. Perform the "ARD Ignition Test" in Cat ET and verify that there are no fuel leaks.
The ARD Ignition Test cannot be performed if the DPF soot loading is above 80%. When the DPF soot loading is above 80%, the Manual DPF Regeneration must be performed using Cat ET.
Proceed to Test Step 7.
7. Perform a "Manual DPF Regeneration"
Note: This test must be performed through Cat ET. The Cat ET service tool enhances the diagnostics during the service test.
A. Clear all codes using Cat ET.
B. Start the engine. Allow the engine to idle for 3 minutes.
Note: Do not use the operators switch for a stationary regeneration. The service tests provide enhanced diagnostics that are necessary for proper troubleshooting and repair.
C. Start a "Manual DPF Regeneration" in Cat ET.
Manual DPF Regeneration
Result: The "Manual
