Toyota Alphard OBD port location

Illustration — use it to know where to look.

Location

Japanese-market AH30 is right-hand drive. The 16-pin OBD socket sits under the dash on the driver's side (right), tucked up behind and slightly right of the steering column, just above the accelerator/footrest area on a metal bracket. It is the white Toyota connector you reach by ducking your head into the footwell — no panel to remove, it faces downward. Same position across every AH30 trim and grade (standard, S, SC, Executive Lounge, hybrid AYH30W and petrol AGH30/GGH30).

Location

Right-hand-drive Japanese-market cars: driver's footwell, to the RIGHT of the steering column, set into the underside of the lower steering-column trim panel — the same panel that carries the bonnet and fuel-flap release levers. Look up from the footwell rather than head-on and you will see the 16-pin socket without removing anything; it sits roughly above the accelerator pedal, outboard of the column. Same position on every AH20 grade, petrol and hybrid, and unchanged by the November 2011 minor change. This record covers the JDM right-hand-drive car only — left-hand-drive AH20s built for Taiwan, the Philippines and the Gulf are a different build and their port position has not been verified here.

How to access

Usually exposed under the dash edge; on some grades a small clip-off plastic trim panel sits over it — unclip it by hand, no tools needed, and the 16-pin socket is right behind.
