94 Legacy Wagon ABS comp location

[Skip]

My 94 GT wagon has it's ABS light on.

I have read where the brain will be flashing a code and that the unit is under the pass. seat.

I have looked under the seat and see a small flap on the outer rail, is this where the brain resides?

It does not look like an ECU for the ABS.

Do wagons put it elsewhere?

Do I have to remove the chair to see this unit?

Thanks for any asistance in this matter.

Under that flap is where the abs brain should be. the flap is only big enough for you to open it and see the flashing led.

Thanks for the reply Craig.

The brain is indeed under the flap

BUT

Maybe our cars are different than the 92 FSM indicates.

My dash "ABS" light is on constantly.

I did a search and read many replies to ABS

problems.

No one has said they have actualy seen this mystery LED on the brain that flashes the error code.

The FSM says LED off means a line voltage problem, so

I removed and tested both relays located on the ABS pump, I also tested the fuse in the under bonnet fuse box - the fuse does have power and is good.

 

I followed the directions in the FSM about driving the vehicle and looked under the flap, used a dental mirror to look at the top bottom and front - no LED

Took a utility knife cut the carpet from the heater duct to the flap.

Still No LED flash - no LED found

So I hacked the carpet to the outer frame rail

Nope no LED. I know what the LED on the F.I. computer looks like, there is no such indicator on my ABS comp.

Has any one personally seen this mystery LED ?

If you have please tell me what side on the comp it is on. I'm beginning to think the LED may have been deleted on the 94 models. Possibly there is a way to make the dash light flash the code?

I have checked all four wheel speed sensors and there pulser rings. They appear clean with no wiring problems.

I may be pulling the pass side chair and back probe the wiring for problems.

Thanks for the reply Craig.

Guess that semi answers my conudrum.

So what is mine a non USDM model?

and more importantly

How do I get the error code?

[GLCraig]

My guess would be that yours has been replaced with one from maybe a later Subaru with OBD2 or that the quit putting the lens in to see the LED at some point.

 

 

right now the only other way I know of to retrive the codes is with a subaru select monitor. I'll have to ask a buddy who's a subaru mechanic.

Thanks for the reply.

Your answer is plausible.

Your number beginging with "B" and mine with "E" may have some bearing.

There appears to be no butchery in the area aside from me and my utility knife. The carpet is undistrubed and appears factory.

Your comp appears taller than mine, the carpet on mine fits snug - if a newer model had been swapped in by some PO I would think the carpet would show this.

A Select Monitor may read the error codes - good idea.

Thanks again for all the help on this bit of a mystery.

My first venture into the nu gen stuff and I think I may go back home where I belong.

I don't think it has to do with being replaced. I do know the later first gen legacies, 92+ did not have the diagnostic O2 light on the ECU, so it's very possible they did the same for the abs computer as well.
