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
