Troubleshooting Test Steps Values Results
1. Check for Active Codes
A. Establish communication between the Caterpillar Electronic Technician (ET) and the 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.
Associated Codes
Result: A 3242-15 or 3242-16 code is active or logged.
Proceed to Test Step 2.
2. Check for Boost Leaks
A. Establish communication between the Caterpillar Electronic Technician (ET) and the ECM. Refer to Troubleshooting, "Electronic Service Tools", if necessary.
B. Perform an "Turbocharger Compressor Bypass Valve Test".
Service Test
Result: The "Turbocharger Compressor Bypass Valve Test" failed.
There is a problem with the Turbocharger Compressor Bypass Valve .
Refer to Troubleshooting, "Turbocharger Compressor Bypass Valve - Test".
Result: The "Turbocharger Compressor Bypass Valve Test" was successful.
Proceed to Test Step 3.
3. Check for High Exhaust Temperatures
A. Several factors can cause a calculated high exhaust temperature. Refer to "Troubleshooting, Exhaust Temperature Is High" for further information on calculated high exhaust temperatures
High Exhaust Temperatures
Result: The engine is experiencing high exhaust temperatures. Repair the cause of the high exhaust temperature.
Result: The engine is not experiencing high exhaust temperatures.
Proceed to Test Step 4.
4. Perform a manual cylinder cutout test.
A. Remove the inlet section (DOC) from the DPF.
B. Perform a manual cylinder cutout test. Manually cut out each cylinder while the exhaust is monitored. As each cylinder is cut out, look for a decrease in white smoke.
Faulty Injector
Result: A faulty injector is found.
Replace any injectors that cause the engine to smoke and run rough when the cylinder is not cut out.
Clean the inside of the inlet section of the DPF.
Assemble the DPF. The engine must be run with no load at 1400 rpm for at least 15 minutes. If the white smoke continues after 15 minutes, the engine must continue to run until there is no white smoke.
Proceed to Test Step 6.
Result: A faulty injector is not found.
Proceed to Test Step 5.
5. Inspect the DPF
A. Remove the inlet section (DOC) from the DPF.
B. Inspect the inside of the inlet section and the front face of the DPF. Look for oil and for excessive soot.
C. Inspect the inlet to the Diesel Oxidation Catalyst (DOC). Inspect the inlet of the catalyst and check the catalyst for plugging.
A small amount of soot is a normal condition. Contact your local technical communicator for Caterpillar engines if you suspect that the amount of soot is excessive. Continue with this procedure after you have received guidance from the technical communicator.
Oil, Excessive Soot or Plugging
Result: Oil is found.
Perform the following procedure:
1. Inspect the outlet of the turbocharger. Clean the oil from the inside of the inlet section of the DPF.
2. Assemble the DPF. The engine must be run with no load at 1400 rpm for at least 15 minutes. If the white smoke continues after 15 minutes, the engine must continue to run until there is no white smoke.
Proceed to Test Step 6.
Result: Oil is not found.
Proceed to Test Step 6.
6. Perform a "Manual DPF Regeneration"
This test must be performed through Cat ET. The Cat ET service tool enhances the diagnostics during the service test.
A. Reset all active codes.
B. Start a "Manual DPF Regeneration".
Test was successful
Result: The "Manual Diesel Particulate Filter Regeneration" was successful.
Return the engine to service.
Result: The "Manual Diesel Particulate Filter Regeneration" was not successful.
Troubleshoot any diagnostic codes that are present.
Complete the procedure in the order in which the steps are listed.
