I got the message, "Air vents remaining: 1" while air vent check with leak tester

Symptom:

The "Air Vent Check" message may appear in the following situations:

1. The pressure regulator is missing from the air injection adapter mounting area on the upper case of the EV battery pack.
   •  
     •  
       •  
         • Solution: Ensure the pressure regulator is properly installed.
2. The silicone O-ring at the bottom of the air injection adapter is missing.
   •  
     •  
       •  
         • Solution: Reassemble the silicone O-ring correctly and remove any foreign substances from the mounting surface.
3. Poor assembly of the *pressure regulator installed on the upper case of the battery, preventing proper seating on the bottom surface.
   •  
     •  
       •  
         • Cause: The pressure regulator may be clogged with foreign substances or improperly assembled.
         • Solution: Clean the mounting area of the *pressure regulator and replace it with a new one if necessary.
