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 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.
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" 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. Or, 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" failed.
Repair: There is a problem with the ARD combustion air system. Refer to Troubleshooting, "ARD Combustion Air - Test".
Result: The "ARD Air System Service Test" passed.
Proceed to Test Step 4.

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.
