L34 6th gen
Illustration — use it to know where to look.
Location
Driver's side, lower dashboard area to the left of the steering column. On the L34 (2019+), the port is tucked behind and above the lower dashboard trim panel and the knee airbag module — it is NOT visible without ducking the head under the dash. A flashlight is required. The port is accessible from beneath the panel without removing any trim; reach up and behind the lower dash fascia to feel for the 16-pin OBD2 connector. Confirmed across multiple owner reports on 2019, 2021, and 2022 Altima models.

Consistent location across all L33 Altima trims (2.5 S, SV, SL, SR; 3.5 SL) and body styles (sedan, coupe 2.5 S and 2.5 SL, 2013-2015 coupe only).
