Result: An associated diagnostic trouble code is present.
Refer to Troubleshooting, "Diagnostic Trouble Codes" in order to troubleshoot the associated diagnostic code.
If the problem is not resolved, proceed to Test Step 2.
2. Ash Service Maintenance
A. Determine the most recent cleaning or replacement of the Diesel Particulate Filter (DPF).
Cleaning interval
Result: The diesel particulate filter was cleaned or replaced within the last 5000 hours.
Proceed to Test Step 3.
Result: The diesel particulate filter was not cleaned or replaced within the last 5000 hours.
Proceed to Test Step 4.
3. Check for Contamination
A. Reset all active codes by using Cat ET.
B. Remove the DPF.
C. Check for contamination on the face of the DPF and the Diesel Oxidation Catalyst (DOC).
Contamination
Result: There is oil, fuel, or coolant on the DPF and/or the DOC.
Perform the following procedure:
1. Clean the DPF. Refer to the engines "Diesel Particulate Filter (DPF) Cleaner Manual" for the cleaning procedure.

3. Reconnect the DOC and the DPF.
4. Start the engine. Run the engine at 1400 RPM with no load. Run the engine for at least 15 minutes or run the engine until there is no more white smoke.
If the 3609-15 diagnostic code remains active replace the DPF. Refer to Special Instruction, REHS8180, "Aftertreatment Filter Maintenance on Tier 4 Final Products Equipped with a Diesel Particulate Filter (DPF), Diesel Oxidation Catalyst (DOC) and a Selective Catalyst Reduction (SCR) Filter". Return the unit to service.
If the DOC needs to be replaced, refer to the Disassembly and Assembly manual for the correct procedure. Perform a DOC reset using Cat ET.
4. Perform an Ash Service
A. Reset all active codes by using Cat ET.
B. Clean the DPF. Refer to Special Instruction, REHS8180, "Aftertreatment Filter Maintenance on Tier 4 Final Products Equipped with a Diesel Particulate Filter (DPF), Diesel Oxidation Catalyst (DOC) and a Selective Catalyst Reduction (SCR) Filter". Refer to Systems Operation and Testing and Adjusting, "Diesel Particulate Filter - Clean" for the correct procedure.
