Note: If failed parts need to be shipped back, please cap off the ports using the caps from the new part.
The DEF injector troubleshooting return form is required and included with failed part returns documenting what was found that led to DEF injector replacement. Attach photos of the DEF injector tip and the mount area along with a Product Status Report to the Service Information Management System claim.
Determine the diagnostic code. ____________________
Troubleshoot the code found using the appropriate troubleshooting manual.
When the troubleshooting procedure requests the DEF quality check, DEF injector resistance measurement, or Dosing Accuracy Test, document the results in Tables 1, 2, and 3.
Table 1
DEF Quality Results
Step Instruction Completed (Yes/No) Units
1 Follow the Testing and Adjusting procedure for "Diesel Exhaust Fluid Quality - Test"
2 DEF Contamination Test (include photo of test strip if possible)
3 DEF Concentration Test

Diesel Exhaust Fluid (DEF) Injector Resistance Measurement
Table 2
Injector Resistance Measurement
Step Instruction Completed (Yes/No) Units
1 Turn the keyswitch to the OFF position. Allow 2 minutes to elapse before proceeding.
2 Disconnect the DEF injector from the applicable harness.
3 Inspect the connector for damage or debris (if damaged take photo).
4 Measure the temperature of the injector (aluminum body). ° C (° F)
5 Connect 2 of the 398-4987 Probe to the DEF injector. The connectors must be used to prevent damage to the DEF injector connector.
6 Measure the resistance of the DEF injector.

Dosing Accuracy Test
Step Instruction Completed (Yes/No) Units
1 Follow the Testing and Adjusting, Aftertreatment SCR System Dosing - Test.
2 Take a photograph of the DEF injector mount, gasket, and bolts on the SCR inlet prior to removal.
3 Remove the injector from the SCR inlet.
4 Take a photograph of the DEF injector mount on the SCR inlet and the tip of the DEF injector. ° C (° F)
5 Run the DEF System Dosing Accuracy test through Cat ET.
6 Use a beaker to measure the amount of fluid from the dosing test. mL (oz)
7 Repeat the test to verify consistency.
mL (oz)
8 Install the injector back onto the SCR Inlet if instructed per the Troubleshooting Guide Results/Comments
