Toyota Previa rust and ODB1 diagnosis location, driver side

Checking rust on Toyota Previa from 1998. Removing plastic parts to watch under them. Also under the mat. Also showing the diagnosis, OBD1.

This Previa was bought in Sweden (EU). And I think sold with some extra rust protection for skandinavia, (salty roads in the winter)

Also showing Diagnosis, OBD1 port under driver seat.
I think you can use Toyodb1 on this port (have not tested it myself yet).
Engine: 2TZ-FE
Engine Controller, ECU: 89661-26660
Toyota Previa model year: 1998

Toyota OBD1 Logger
From Google Play you download the Android App TOYOBD1 from ZFApps. It uses about 8 Mb.  You also need the OBD1READ device that you connect to your Diagnosis outlet (OBD1)

So what do OBD1 mean? OnBoard Diagnostics 1

Around 1996 OBD2 became standard  in USA, some cars got it earlier. (USA was first, Europe not so much, 2001 EU joined with EOBD. My Previa from 1998 do have OBD1)
