But i have drive the car last summer before i repaint the svx, and change the clutch. And then the car have now problem whit the jump wire or steering. But then i not have speedo that works. This i also have fix in this summer.

But will i have CheckEngine light if i disconnect the jump wire?

All is not normal Alex. Those two wires, that the jumper is connected to, should both have 5V on them, supplied from the ECU. It would appear that one of them doesn't, so that the other one is supplying it through the jumper wire.
I think this problem may go back to the accident that you had with the battery jump.

To see if that is the problem, cut the jumper wire again, and use a multi meter to measure the voltage of the Black/yellow Torque Control wire, and the Green/white Steering wire, to ground, see if they both have 5V.

Little late answere but i have been sick, so i have dont have had time to check it.
But i think i take a trip to day and look at it.

If i have understand this right both wire should have 5v on them whit out the jump wire, if it have so then the jump wire should bee there? And the problem is some where else?

[Alex-svx]

I have check the wiring on the ecu.
And the only wiring that have 5v is the green white wiring. But today there is no Check engine light. I try to steer the wheel to the left and right. And its seen ok. No light came up. like i try before and then the light came on.
But i have not take the car out for a test drive.
It was a car in the garage that block me. But i will take a test drive soon.

And the battery has been off the car for a week.

OK what is happening is that the Torque Control wire is getting its 5V from the Green/White wire, through the jumper wire, instead from the ECU.
When you turn the steering the switch on the PS pump grounds the Green/White wire like it should, but this also grounds the Torque control wire through the jumper wire, to cut the torque. When you cut the jumper wire, the Torque Control looses the 5V and posts a code.

Thats the long version, the short version is that either the Black-Yellow wire that runs from that plug to the TCU plug, has a problem, or more likely the ECU has a problem in not supplying the 5V. I think you still have a problem caused by the Battery jump mistake.

Ok. So the ecu dont send the message it should? Can this bee that i use a RHD ecu when my car is a LHD? Or is the some other sensores or realy that have been damage?

How can this been check by a diagnostic from subaru?

I don't think the RHD ECU, fitted to a LHD would make any difference.

I do think it is the ECU that is faulty, but if every thing else works OK, and it is just the Torque Control that is not right, we may be able to do something to get around that problem. I will have a look at the circuitry to see what can be done.

OK we need to change the jumper wire, from the Power Steering white/green wire, at B60 pin 7, to B60 pin 3, red wire. Same plug, top row.

This change will do the job of supplying the 5V, the the ECU doesn't, with out interfering with any other circuit.

You can see the wires here.

Hello thanks ALOT for look at this for me.
I will take a trip down tomorrow.
and try to fit the wired. This is the wired next to the Black/white one on the same plug? If i see right and understand the pictures.

Thanks again.
And i will tell you how this work out so fast i have try to check this.

No mate, not the plug that the Black/yellow wire is on, it is the next plug, that the White/green wire is on.
If you look at the pict you can just see the red wire, 4 pins to the right of the white/green wire, just above the right hand Scotch Lock connector, under the "O" of "cOrner"

Now i have try the car. And install the jump wire. (on my car the wire was yellow whit red stripe) the 4 wiring from the grenn/whie one top row.

But still the car wont go when i turn the steering wheel. It also feel little hard then other cars whit power steering. And after a 3min test drive the check engine light comes on. And the error is still 38.

No wrong wire!. It is on the row below that one. The white/green is in No.7, you need the Red wire in No.3, on the row below the Yellow/red.

7.8.9.10.11.12
1.2.3,.4. 5 ,.6.

Ok. So its the wiring under the g/w one. There its to red wire right?
if i remeber right from yesterday so if i go from left then is bee the first red wire?

Yes the red wire on the row under the white/green.

You are my HERO Harvey.

I have test drive the car whit the right wiring now. And the car goes like Good. No jumping when turing the steering wheels.

And none check engine light. I have miss how fun its to drive little fast.
I have drive a suburban 6.2 diesel and the svx goes little better.

Thanks alot for helping me and have patience to hold out.

Now my plans its to replace the gearbox from a 5 speed form 2.5L.
And replace some gasked and shine up the engine bay in the winter.

Oh good work Alex.
That was a bit hard to relate to you, but you got there, don't get many interesting, ones like that one.

Cheers Harvey.
