It's not exactly fun.

 

You need to remove the bottom plastic piece under the dash, and that should give you access to the ECU & TCU. You'll probably have to remove the TCU which is held in with two 10mm nuts to get at the ECU.

Thats not what I wanted to hear.

Had to order a O2 sensor ...won't have it till Monday.

Going to take the 90 Legacy to see its mom tomorrow.

I will see what my semi-local Subaru service department can

tell me about why my AWD does not work

I still need to replace the ECU, going salvage yard shopping Saturday

looking for one. I asked Blackbart...he didnt have one but said he would

see what he could find, so unless I get lucky Saturday everything

will be at a stand still.

 

Thanks Very Much to all who have helped me

Well just got back from the Subaru service department....they tell me my AWD

is working fine. They test it on a lift and pull the parking brake . It definitely

turns the back wheels against the brake. But last winter it would spin

the front tires and the rears didn't seem to be doing anything. They sure

didn't spin on ice when the front was spinning then.

Other than being $75 lighter I really don't know any more than I did

before the visit.

Anyone know how to test the AWD and get a definite answer.

I think its on the rear...I can hear it when I pull the handle.

At least I hope thats what I hear.

But there must be a Subaru "approved" way to test the AWD

for function.

sigh, the dealer has no idea what hes doing

SUbarus the front wheels are always connected to the driveline. The rear wheels are the controled wheels. Of course the front wheels will sopin if you raise the parking brake.

The dealer was an idiot. He didnt do a damn thing.

I meant the testing procedure to say that the rear wheels

did turn against the parking brake when it was pulled. The front

was spinning all the time.

lets go back to the very begining. WHy do you feel its not working

lets go back to the very begining. WHy do you feel its not working

 

Previous owner said last winter it spun the front tires. Rear tires never

spun, only moved at a speed equal to what the car moved.

I would expect front and rear to spin on ice when trying to make them

spin. I bought the car at a price that reflected a non-working AWD.

I could not get the reat tires to spin in gravel when I tried last

weekend. Only the front would spin.

I would expect all wheels to spin at least a little for a brief time.

not necassarily. Put the FWD fuse in the holder, and see what the difference is

Yes that kills it working on a lift...it just seems that it should do

more with all 4 wheels on a slick surface. Maybe not...This is my

first Subaru and only had it a few months. It was garage kept and

is as clean as a new car, uses no oil in 4000 miles.

If its doing what it should then the last owner (who has had 4

subaru's) outsmarted himself and sold me a bargain.

no put it in and drive the car on the ground. Floor it on a slick wet, or if it will spin tires on dry durface, do that. next put the fuse in and repeat.

Ok will try it tomorrow and let you know what happens. Time to call

it a night. I get up a 5 am.

 

Thanks

Richard, how did this all play out for you? What was your final find/discovery/fix?

We have a 1990 Legacy, automatic, build date 10/89 as well. We had codes 45 and 22. We got the knock sensor replaced, now we need to address the Atmospheric Pressure Sensor.  I am curious if your finds can save us a little time in this process??

Thank you much!
