Missing a key concept on reading Subaru trouble codes?

[bill_hale]

Previously posted in the group is a method to use check
engine light flashes to read codes. I have some service info on my 95
Impreza that has CEL ON. I've located the two connectors. I want
to do the check and can count light pulses!

My quandry is: What do they connect to? The data gives a
matrix of the two: Connected, not connected. To what? What
am I missing? Is there a tool? My matrix would have just two lines:
1) Connected to each other; 2) Not connected to each other.
That doesn't seem right.

What am I missing? Am I too dumb to perform this test? Am I missing
a tool?

Thanks, Bill Hale Loveland CO

Subaru Trouble Codes


--- CODE RETRIEVAL --


There are self diagnostic connectors on all models which, when
connected together with the key in the ON position (engine off) flash
diagnostic codes through the LED light on the Oxygen Monitor on the
ECU. The connectors are under the steering wheel, to the left of the
Oxygen Monitor on most models. On Carbureted and Single-Point Fuel
Injected 1989 Models, the test connectors are located on the engine
side
of the firewall, on the driver's side. Impreza models have the ECU
and
test connectors located behind the right side of the dash instead of
the
left. On SVX models the connectors are located behind the driver's
kick panel.


There are four test modes. With NEITHER test connector
connected,
and the key in the ON (engine off) position, the light will display
codes
that relate to starting and driving. With ONLY the "Read Memory"
connector connected, historic codes will be displayed. With ONLY the
"Test Mode" connector connected, a dealership technician can perform
dynamic tests. The last mode is for clearing codes (see below).

Also some 95 Subarus were OBDII. Be sure yours is OBDI or the
DIY-light flash method won't work.

Thanks for the help. This website is better than my printed materials.

There is still something goofy... mine doesn't agree with any of the
pix
exactly.

It's a 95 impreza 1.8. There is nothing on the right hand side except
heaters.

The left connector is a single one--no mate anywhere. It has 2 female
blade shape pins, with green-wh stripe and wh-blk stripe wires going
into it.
It has a grey top.

The right connectors... there are two a male and female that will plug
together. They each have a single wire, one black and one red.

I'm about to plug these together and see if I can read some codes.
