I supplied information elsewhere in this thread - but I'll repeat it
here.
The Cressida you have has a Toyota Diagnostic outlet as opposed to the
US Market OBDII, as you've probably gathered.
IMO, you probably should get at a wiring diagram and change the thing
over to the now common OBDII as used universally. It's not as if you'll
be giving the thing to the dealer to play wth, and it's dubious whether
there's anyone there old enough to remember how the diagnosis system
works.
That's because OBDII is an actual standard, cooked up between the
Septics and the Euro types, which was (apparently) resisted by the Japs
until it became obvious that they'd have to comply. In fact, OBDII is
Compulsory in some countries.
But I'm at a loss to understand what you need it for. Really.
Are you pissing about trying to get raw data for some sort of display,
or sensor information re mixture settings?
The shorting of the pins procedure is all that's required to get a
reading of the fault codes if any, as Toyota designed the thing to
reveal fault codes 'in the field'
The diagnosis thing is only to save time for dealerships appropriately
equipped, and as it happens, they also get to gouge you for the use of
the trick system.
There's a more of less duplicate plug under the bonnet, where you can't
see the fault light display and it's used when you're setting stuff such
as timing, TPS etc, and that's the one most mechanics play with. Yes,
even Toyota dealership types.
The only thing Toyota really lets you play with is Base Idle, and that
only with some reluctance - and all else in the ECU program hangs off
that.
There are things with Apexi written on them that let you warp the
mixture and stuff, but they're really geared towards turbocars and are
usually used to bodgy the settings so you can play risky games and know
why you blew the bastard up.
And they're handy for suprise attacks on boy racers.
But as a forinstance, if you're having idle problems, then you need to
cure that by finding the vacuum leak (usual) else the partial or full
blockage of the passages associated with the ICU (also usual). But all
that's another story.
There are other problems 7M installations get, but these are the big
hitters and, along with the stupid dead-ended coolant pipe LHS rear of
the engine is usually the progenitor of the head-gasket problem they
have.
