Troubleshooting Test Steps Values Results
1. Check the resistance of the DEF Injector.
A. Turn the keyswitch to OFF. Allow 2 minutes to elapse before proceeding.
B. Disconnect the DEF injector from the applicable harness.
C. Inspect the connector for damage or debris.
D. Connect two 398-4987 Connectors to the DEF injector. The connectors must be used to prevent damage to the DEF injector connector.
E. Measure the resistance of the DEF injector.
Ohms
Result : The resistance of the DEF injector measured between 10 Ohms to 20 Ohms.
Proceed to Test Step 2.
Result : The resistance of the DEF injector did not measure between 10 Ohms to 20 Ohms. A failed DEF injector has been detected.
Repair : Replace the failed DEF injector.
Proceed to Test Step 7.
2. Check for a short circuit in the wiring harness.
A. Turn the keyswitch to OFF. Allow 2 minutes to elapse before proceeding.
B. Disconnect the injector from the applicable harness.
C. Connect two 398-4985 Connectors to the DEF injector harness connector. The connectors must be used to prevent damage to the DEF injector connector.
D. Measure the resistance between the DEF injector positive wire and the DEF injector negative wire at the DEF injector connector.
Note : The reading will measure the resistance in the wiring harness between the DEF injector connector and the DCU.
Ohms
Result : The resistance of the DEF injector wiring harness measured greater than 10K Ohms.
Repair : Connect the injector to the applicable harness.
Proceed to Test Step 3.
Result : The resistance of the DEF injector wiring harness did not measure greater than 10K Ohms.
Repair : There is a short circuit in the wiring harness between the DEF injector connector and the DCU. Repair or replace the wiring harness. Connect the injector to the applicable harness.
Proceed to Test Step 8.
3. 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 within the acceptable range.
Proceed to Test Step 4.
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 8.
Result : The DEF is contaminated.
Repair : Contact the Dealer Solutions Network (DSN) for further information.
4. 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 below specification.
Proceed to Test Step 5.
Result : The quantity collected is within specifications.
Repair: Install the DEF injector.
Proceed to Test Step 8.
Result : The quantity collected is above specification. A failed DEF injector has been detected.
Repair : Replace the DEF injector.
Proceed to Test Step 7.
5 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.
Restriction, Obstructions, and Leaks
Result : An obstruction was found.
Repair : Flush or replace the line.
Proceed to Test Step 7.
Result : An obstruction was not found.
Proceed to Test Step 6.
6. Replace the DEF injector.
A. Turn the keyswitch to OFF.
B. Remove the DEF injector.
C. Connect the new DEF injector to the DEF pressure line and the electrical connector.
Note : Do not install the new injector until Test Step 7 has been completed.
DEF Injector
Result: The DEF injector was connected to the DEF pressure line and the electrical connector.
Proceed to Test Step 7.
7. 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 specification. Install the DEF injector.
Proceed to Test Step 8
Result: The quantity collected is not within specifications.
Repair : Replace the DEF pump. Reinstall the DEF injector.
Proceed to Test Step 8.
8. Perform an "Aftertreatment System Functional Test"
A. Turn the keyswitch to ON.
B. Connect to Cat ET.
C. Perform an "Aftertreatment System Functional Test" using Cat ET.
D. Download a warranty report. Refer to "Aftertreatment Abnormal Shutdown History" under the "Information" tab in the "Engine #1 Aftertreatment Controller".
Note : If Hot shutdowns have occurred, allow the engine to cool down before shutting off the machine.
Cat ET Test
Result : The test was successful.
Return the unit to service.
Result : The test was not successful and more codes were logged.
Repair : Troubleshoot the additional codes.
