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.
