Troubleshooting Test Steps    Values    Results    
1. Check for Diagnostic Codes that are Active
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. Check and record any diagnostic codes that are active or logged. Look for the following diagnostic codes:
1. E1239 (1) or 3750-31
2. E993 (3) or 3703-31
3. E1040 (2) or 3530-31
D. Wait at least 30 seconds in order for the diagnostic codes to become active.
   
Diagnostic Code
   
Result: A E1239 (1) or 3750-31 diagnostic code is present, proceed to Test Step 2.
Result: A E993 (3) or 3703-31 diagnostic code is present, proceed to Test Step 3.
Result: A E1040 (2) or 3530-31 diagnostic code is present, proceed to Test Step 4.
Result: A E1300 (1) or 3716-15 diagnostic code is present, proceed to Test Step 5.
Result: A E1301 (1) or 3712-15 diagnostic code is present, proceed to Test Step 6.
Result: A E1302 (1) or 3750-15 diagnostic code is present, proceed to Test Step 7.
Result: A E1305 (1) or 3483-11 diagnostic code is present, proceed to Test Step 8.
   
2. A E1239 (1) or 3750-31 Diagnostic Code is Present.
A. The operator did not allow enough time for regeneration to occur. The operator must respond when the DPF lamp is illuminated. Once the DPF and action lamp are illuminated, the operator must allow the engine to idle until the soot load is reduced to 50 percent .
   
Proper Operation
   
Result: Refer to the Operation and Maintenance Manual, "Caterpillar Regeneration System (CRS) Aftertreatment Switch" for the proper operation of the regeneration system.
Return the unit to service.
   
3. A E993 (3) or 3703-31 Diagnostic Code is Present.
A. The operator has disabled the regeneration system and a regeneration is necessary.
   
Disabled Regeneration
   
Result: Perform a regeneration. Refer to the Operation and Maintenance Manual, "Caterpillar Regeneration System (CRS) Aftertreatment Switch" for the proper operation of the regeneration system.
Return the unit to service.
   
4. A E1040 (2) or 3530-31 Diagnostic Code is Present.
A. The regeneration system is disabled by Cat ET.
   
Regeneration Disabled by Cat ET
   
Result: Establish communication between Cat ET and the engine ECM. Set the value of the "Aftertreatment Regeneration Device" from "Disabled" to "Enabled".
Return the unit to service.
   
5. Aftertreatment Regeneration Cannot Start Due To Low Engine Temperature
A. The engine temperature is too low for an aftertreatment regeneration.
   
Low Engine Temperature
   
Result: Raise the coolant temperature above
40° C (104° F ) and the Diesel Particulate Filter inlet temperature above
50° C (122° F). If the ambient temperature is
-15° C (5° F) or below, the coolant temperature must be above
60° C (140° F) for an active regeneration to begin.
Repair: Perform a "Manual DPF Regeneration" using Cat ET.
Return the unit to service.
   
6. Aftertreatment Regeneration Cannot Start Due to System Fault
A. Establish communication between the Cat Electronic Technician (ET) and the engine Electronic Control Module (ECM).
B. Check for active faults related to the ARD combustion
