Troubleshooting Test Steps Values Results
1. Check the Diesel Exhaust Fluid (DEF) Quality.
A. Measure the DEF quality. Refer to Testing and Adjusting, "Diesel Exhaust Fluid Quality - Test" for the correct procedure.
DEF Quality
Result : The DEF is not contaminated and the concentration is not within the acceptable range.
Repair : Drain the DEF from the tank. Refill the tank with DEF that meets ISO 22241 quality standards.
Proceed to Test Step 3.
Result : The DEF is not contaminated and the concentration is within the acceptable range.
Proceed to Test Step 2.
Result : The DEF is contaminated.
Repair : Contact the Dealer Solution Network (DSN) for further information.
2. Perform the "DEF Dosing System Accuracy Test" Using Cat® Electronic Technician (ET)
A. Refer to Testing and Adjusting, Aftertreatment SCR System Dosing Test, for the correct procedure.
DEF Dosing System Accuracy Test
Result : The quantity collected is within specifications.
Repair : Install the DEF injector.
Proceed to Test Step 4.
Result : The quantity collected is below specification.
Proceed to Test Step 3.
Result : The quantity collected is above specification. A failed DEF injector has been detected.
Repair : Replace the failed DEF injector.
Proceed to Test Step 4.
3. Check the DEF Pressure Line.
A. Turn the keyswitch to OFF. Allow 2 minutes to elapse before proceeding.
B. Visually inspect the lines for leaks or damage.
C. Remove the DEF pressure line between the DEF pump and the DEF injector.
D. Inspect the DEF pressure line for obstructions. Flush the line with water or low-pressure air, if necessary.
Note: Possible obstructions are ice, DEF deposits, or debris.
Restrictions, Obstructions, or Leaks
Result : An obstruction was found.
Repair : Flush or replace the line. Install the DEF injector.
Proceed to Test Step 4.
Result : An obstruction was not found.
Repair : Proceed to Troubleshooting, "DEF Pressure is Low".
4. Perform an "Aftertreatment System Functional Test"
A. Establish communication between Cat ET and the engine Electronic Control Module (ECM).
B. Perform a "Aftertreatment System Functional Test" using Cat ET.
Successful Test
Result : The test completed successfully.
Return the unit to service.
Result : The test did not complete successfully.
Proceed to Test Step 5.
5. Check for an Engine Misfire
A. Establish communication between Cat ET and the engine ECM.
B. Perform a "Cylinder Cutout Test".
Misfire
Result : A misfire was detected.
Repair : Replace or repair the failed component or components.
Proceed to Test Step 7.
Result : A misfire was not detected.
Proceed to Test Step 6.
6. Check the Exhaust System for Leaks
A. Check the entire exhaust system for leaks.
Exhaust Leaks
Result: There were not any exhaust leaks found.
Repair : For a 3216-7 or E1431 (2) code replace the intake NOx sensor.
Repair : For a 3226-7 or E1432 (2) code replace the outlet NOx sensor.
Proceed to Test Step 7.
Result : There were exhaust leaks found.
Repair : Repair the exhaust leaks.
Proceed to Test Step 7.
7. Perform the "Aftertreatment System Functional Test" in Cat ET
A. Establish communication between Cat ET and the engine ECM.
B. Perform the "Aftertreatment System Functional Test".
Successful Test
Result: The test completed successfully.
Return the unit to service.
