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
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 2.
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 Solutions Network (DSN) for further information.
2. Perform a "DEF Dosing System Accuracy Test"
A. Perform a "DEF Dosing System Accuracy Test" using Cat® Electronic Technician (ET). 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 DEF injector.
Proceed to Test Step 6.
3. Check the DEF Pressure Line
A. Turn the keyswitch to OFF for 2 minutes. The keyswitch must be OFF for 2 minutes to allow the DEF pump to purge, reset the code, and reset the Diesel Exhaust Fluid Controller (DCU).
B. Visually inspect the lines for leaks or damage.
C. Remove the DEF pressure line between the DEF pump and the DEF injector.
D. Check for ice, urea deposits, or debris in the DEF pressure line.
DEF Pressure Line
Result : There are restrictions or leaks in the lines.
Repair : Remove the restrictions or replace the pressure line.
Proceed to Test Step 6.
Result : There are no restrictions or leaks in the lines.
Proceed to Troubleshooting, "DEF Pressure is Low".
4. Inspect the Exhaust Mixer for DEF Deposits
A. Turn the keyswitch to OFF.
B. Remove the DPF outlet.
C. Inspect the exhaust mixer for DEF deposits.
Exhaust Mixer
Result : There were no DEF deposits on the exhaust mixer.
