WARNING: This page is about a different car, the 2018 Nissan Titan XD. However, it is still accessible from the selected car via links, so may be relevant.
  1. Turn ignition switch ON.
  2. Select "DEF System Leak Test" in "Active Test" mode of "ENGINE" using CONSULT.
  3. Touch "Start". During the initialization of this test, a note will appear on the screen indicating that the system has reached a primed state.
NOTE:
  • The dosing system should prime in under 1 minute for a system without leaks. If the dosing system does not prime, it may be due to a leak in the dosing valve or supply line.
  • If the system fails to prime, a key cycle will be required before attempting to run the DEF System Leak Test again.
  • The DEF System Leak Test can only be attempted twice consecutively. A key cycle will be required before attempting to run the DEF System Leak Test again after two attempts.
