• E995 (2) or 3719-16
• E995 (3) or 3719-0
• E991 (3) or 3715-31
• E992 (3) or 3714-31
Codes
Result: A E991 (3) or 3715-31 code is present.
Proceed to Test Step 2.
Result: One of the following codes are present:
• E995 (2) or 3719-16
• E995 (3) or 3719-0
• E992 (3) or 3714-31
Proceed to Test Step 3.
2. E991 (3) or 3715-31 code
A. The E991 (3) or 3715-31 code indicates that the engine has continued to run after repeated warnings and engine shutdowns. The DPF must be replaced. Refer to the Disassembly and Assembly, "Diesel Particulate Filter - Remove and Install (Clean Emissions Module)" for the correct procedure.
DPF
Result: A E991 (3) or 3715-31 code is present.
Repair: Replace the DPF.
After the DPF has been replaced, clear the E991 (3) or 3715-31 code ( a factory password will be necessary).
Proceed to Test Step 3.
3. Associated Codes
A. Establish communication between Cat ET and the ECM.
B. Check Cat ET for any associated codes that are listed in Table 2.
Associated Codes
Result: An associated code is not active or logged.
Proceed to Test Step 4.
Result: An associated code is active or logged.
Repair: Troubleshoot any codes that are present before continuing with this procedure.
4. Manual DPF Regeneration
Note: Do not use the cab switch for stationary regeneration. The service tests provide enhanced diagnostics that are necessary for proper troubleshooting and repair.
A. Start a "Manual DPF Regeneration" in Cat ET.
Manual DPF Regeneration
Result: The "Manual DPF Regeneration" was successful.
Return the engine to service.
Result: The "Manual DPF Regeneration" not was successful.
Repair: Troubleshoot the diagnostic codes that are present.
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).
