Troubleshooting Test Steps Values Results
1. Check for Codes
A. Connect Cat® Electronic Technician (ET) to the service tool connector. Refer to Troubleshooting, "Electronic Service Tools", if necessary.
B. Determine if a code is present.
Codes
Result : A 4360-16 or E946 (2) code with an ETI of 1 or 2 is active or logged.
Proceed to Test Step 2.
Result : A 4360-17, E947 (1), 4360-18 or E947 (2) code is logged or active.
Proceed to Test Step 2.
2. Check the operation of the SCR catalyst inlet temperature sensor.
Note : Only perform this step on a cold engine.
A. Remove the SCR catalyst inlet temperature sensor and allow the sensor to rest in ambient air for 2 minutes.
B. Connect to the engine ECM by using Cat ET.
C. Monitor the value of the SCR catalyst inlet temperature sensor on Cat ET.
Sensor
Result : The value of the SCR catalyst inlet temperature sensor is within 9° C (15° F) of ambient temperature.
Repair : Reinstall the sensor. torque the sensor to the proper specification.
For a 4360-16 or E946 (2) codes proceed to Test Step 4.
For a 4360-17, E947 (1), 4360-18 or E947 (2) code proceed to Test Step 3.
Result : The value of the SCR catalyst inlet temperature sensor is not within 9° C (15° F) of ambient temperature.
Repair : Replace the SCR catalyst inlet temperature sensor. Refer to the Disassembly and Assembly manual for more information.
Proceed to Test Step 5.
3. Check for exhaust leaks.
A. Start the engine.
B. Check the exhaust system for proper installation.
C. Check for proper installation of the exhaust system insulation.
D. Inspect the exhaust system between the DPF and the SCR for signs of an exhaust leak.
E. Inspect the SCR inlet temperature sensor to ensure proper installation in the sensor port.
Exhaust leaks
Result : There were exhaust leaks found.
Repair : Repair or replace the component that is causing an exhaust leak.
Proceed to Test Step 5.
4. Check the Diesel Exhaust Fluid (DEF) quality.
A. Measure the DEF quality. Refer to the Testing and Adjusting, "Diesel Exhaust Fluid Quality - Test" for the correct procedure.
DEF
Result : The DEF is not contaminated.
Repair : Check the exhaust system for fuel. Refer to Troubleshooting, "Exhaust System Contains Fuel".
