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 additional information.
DEF Quality
Result: The DEF is not contaminated and the concentration is within the acceptable range.
Proceed to Test Step 2.
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 contaminated.
Repair: Contact the Dealer Solution Network (DSN) for further information.
2. Perform a "DEF Dosing System Accuracy Test"
A. Connect Cat® Electronic Technician (ET) to the service tool.
B. Use Cat ET to perform the following dosing test:
- "DEF Dosing System Accuracy Test"
Refer to Testing and Adjusting, "Aftertreatment SCR System Dosing Test" for additional information.
Min. 170 mL
Max. 190 mL
Result: The amount of DEF collected for one or more DEF injectors was below 170 mL.
Proceed to Test Step 3.
Result: The amount of DEF collected for one or more DEF injectors within the desired range (170 mL to 190 mL). Reinstall the DEF injector.
Proceed to Test Step 4.
Result: The amount of DEF collected for one or more DEF injectors was above 190 mL. A failed DEF injector has been detected.
Repair: Replace the failed DEF injector. Refer to the Disassembly and Assembly manual for additional information.
Proceed to Test Step 4.
3. Check the DEF Pressure Line
A. Turn the keyswitch to the OFF position. Allow 2 minutes to elapse before proceeding.
B. Visually inspect all the lines for leaks or damage.
C. Remove each DEF pressure line between the DEF pump and the DEF injector. Refer to the Disassembly and Assembly manual for additional information.
D. Inspect each DEF pressure line for obstructions. Flush each line with water or low-pressure air, if necessary. Possible obstructions are ice, DEF deposits, or debris.
Restrictions, Obstructions, or Leaks
Result: There are restrictions or leaks in the lines.
Repair: Remove the restrictions or replace the pressure line.
Proceed to Test Step 4.
Result: There are no restrictions or leaks in the lines.
Repair: Refer to Troubleshooting, "DEF Pressure is Low" for additional information.
Verify that the repair eliminated the problem.
4. Perform an "Aftertreatment System Functional Test"
A. Connect Cat ET.
B. Use Cat ET to perform the following dosing test:
- "Aftertreatment System Functional Test"
Test
Result: The test was successful.
Return to service.
If the procedure did not correct the issue, contact your Cat dealer Technical Communicator (TC). For further assistance, your TC can confer with the Dealer Solutions Network (DSN).
