Information:

Introduction
Do not perform any procedure in this Special Instruction until you have read the information and you understand the information.DEF injectors are being replaced in the field and returned to Caterpillar for testing. Results of the testing are finding a large portion of the returned DEF injectors are found to be fault not repeated.This form is to be used and filled out in any case that a DEF injector is being replaced.The DEF injector troubleshooting return form needs to be completed and included within failed part returns documenting what was found that led to DEF injector replacement. Attach the photos of DEF injector tip and mount area along with a Product Status Report to the SIMS claim.References

DEF Quality Results
Step Instruction Completed (Yes/No) Result Comments Units
1 Follow the Testing and Adjusting procedure for "Diesel Exhaust Fluid Quality - Test"
2 DEF Contamination Test Pass / Fail
3 DEF Concentration Test % at 20° C (68° F)

Injector Resistance Measurement
Step Instruction Completed (Yes/No) Result Comments Units
1 Turn the keyswitch to the OFF position. Allow 2 minutes to elapse before proceeding.
2 Disconnect the DEF injectors from the applicable harness.
3 Inspect the connector for damage and debris.
4 Measure the temperature of the injector (aluminum body). C
5 Connect two 398-4987 Probes to the DEF injector. The connectors must be used to prevent damage to the DEF injector connector. Reference Illustration 1 for example.
6 Measure the resistance of the DEF injector. Ohms
Table 4
Dosing Accuracy Test
Step Instruction Completed (Yes/No) Result Comments Units
1 Follow the Testing and Adjusting procedure for "Aftertreatment SCR System Dosing - Test"
2 Remove the injector from the DPF outlet.
3 Take a photograph of the DEF injector mount on the DPF outlet and the tip of the DEF injector.
4 Install the injector on the beaker.
5 Run the DEF System Dosing Accuracy test through Cat® Electronic Technician (ET).
6 Use the beaker to measure the amount of fluid from the dosing test. ml
7 Repeat the test to verify consistency. ml
8 Install the injector back onto the DPF outlet.
