Passenger seat issue
Hi Guys,
So, last night I got into my wife's car and she went to move the seat, and she accidentally moved the seat forward when she really wanted to move it back. Weird thing is, it moves forward, but won't move back. This is the same for the seat back (tilt) and the forward/backward movement. Trying to use the memory positions, seemed to only move the seat forward too.
So basically, the seat is almost all the way forward and tilted all the way forward, and I can't get it to go backwards. I read a bunch of threads on here that seem like the same problem, but nothing is super clear as to how to resolve it. Do I hold all three memory buttons in at the same time while making the seat be at the front most position??? I'm confused..
Any help clearing this up would be appreciated.

Similar issue on mine. Both, forward and aft functions stopped working, everything else worked flawless.
I needed to replace a seat control board in order for everything to function properly again.
Good luck.

Extra information
Well, last night I tried to see what actually going on. The seat is about half way forward, but will not go back all the way. I can drive the seat all the way forward, but will only go back to that "midway" point. So, the motors and switches are working fine. Its as if the seat thinks it has a new starting point.
This is why I think something needs to be reset.

Mine was doing same and the reset with the STAR system fixed it.

So....
So, would unplugging the battery maybe rest the logic? Or, pulling the fuse for the seats? Seems crazy to have to have the system reset that way. I'm not doubting you guys, but man that is probably costly....

Tried but no go
So, last night I tried the synchronization process last night, and no changes. Not sure if I have to have the key on to perform this, but I did not. I just walked up to the car and moved the seat all the way forward and held the switch in that position for 2+ seconds. Then, moved it as far back as it would go (about half way) and held the button. But, no changes.
Is the memory for this seat held somewhere within the seat, or in the computer somewhere else in the car? That would really tell me what my nest step is.
Seems like I will have to have the wife drop the car off at the local Indy shop next week. Bummer!!!

You can try pulling driver seat adjustment control unit fuses for a while then reinsert in an attempt to clear: interior (side dash) f34 & rear SAM (left trunk) f1.

No go
Tried the procedure like the YouTube video, but no dice. Moved the base all the way forward, then tilted the seat all the way forward, then moved the back all the way forward. Each movement was completed with a 2 second pause. Still the seat will only return to the halfway back and the tilt only to the straight up and down location. Darn it!

Tried it
Do have a question. Can I unplug the connectors under the seat? Might this allow the program to bleed off the memory? Vaguely remember something about being cautious about doing this? Don't want to accidentally trigger the safety system or something... lol
Thanks guys for your help!!

See image. No guarantee as it may work, may not - a last effort before having someone normalize control unit via SDS. Switch off ignition and remove key from ignition, Keyless-go locate key outside of transmission range – remove both fuses simultaneously, wait at least 10 minutes before reinserting.

Konigstiger,
Here is the latest. I just saw your post, but in the meantime I had the wife swing the car by the indie shop. Apparently, the mechanic could move the seat back to its farthest back positions, and move all three axis of the seat, so that was good. But, when he went to use the switches, the seat would go back to its weird state. It would move forward, but then only move back to the halfway positions. I asked if they tried to program the memory position, to the far back position and just leave it as it. He tried that, but that didn't help either. He is thinking the switch, but that makes no sense to me. You can make the seat move back and forth, you just cannot make it drive all the way back once you pass a certain point. This is for all three axis.
Any ideas? I still think its a program issue. Like its stuck in a re-sync mode or maybe a memory mode of sorts?

Will do...
Konigstiger,
I will do that tonight when I get home. Thanks!!
The thing is, (thinking out loud), why would it be the switch. I can move the seat forward and back in each of the three axis. If it were a switch, wouldn't it be only one axis having the issue? Unless....The Memory button is the problem. Causing all the axis to go back to these "preset" locations?
Thoughts???

Well, I went over all the stuff again (fuses and re-syncing) the seat, but its stuck on stupid still. lol
Need to decide whether I just buy a switch and try that or let the wife take it to the indie and see what he comes with. Ugh
Sitting here thinking about this and I just cannot see the switch being the issue. Sorry, maybe I'm just stubborn. Each of the three seat axis (tilt, base forward/backward, up&down) all work, but will not go negative past the mid-line position. To me, you guys are right. Its a program issue. Won't normalize. Not sure why the indie could not reset it?? I guess I will just turn it in to the shop and see what they come up with. Hopefully it wont turn into a troubleshooting nightmare....at my cost.
We shall see... I'll report back on what they find.

Have you taken the seat out and looked for travel limiting sensors? (talking out my butt here cuz I have no idea if there are these switches present)
If the sensor has moved from where it should be that could be your issue...
but I could be completely wrong too.
If it was me, I'd remove the seat and see what I can see.

Rapidoxidation,
At this point nothing is out there. But, everything is working fine. Just that "something" is telling all three seat axis (movements) won't go past the have way point. So each seat movement will go forward and back, but not past the mid point of travel. Example, the seat is straight up and down and will go forward, and the seat is half way back (mid-line) of travel. Won't go past these points. So, I don't think all three sensors moved.
Thinking out loud...

Cant shake this issue, so I told the wife to swing the car to another indie near her work. They seem to know the issue when I spoke to them over the phone. Will update when I know more....

One more question
Konigstiger,
Since the wife has yet to drop the car off, I was wondering. Is it OK for me to unplug ALL the connectors underneath the seat to just double-check the connections? I'm a little leary, as I don't want to set off the SRS system or anything like that.
Just a thought....
