Abrams

I finally found some time to look for my vss signal and found it very easily. The reson everyone else might be having problems finding it, is because the wire is not present on cars with out the factory nav.

see photo below for the proof :captainobvious:

Thanks So Much!!!!!!! You The Man

Tsx536

Great find Abrams!!

Did you end up hookin the VSS wire up?
Also, where is the ECU located in our car?
What is required to get to it?

Thanks..man!

Abrams

I will be doing the job this weekend and will post all the pics then.

nguyenzpry

i know my job of hooking the vss wire up is shitty but....all i did was splicing the vss wire, stick it down all the way through that hole in pin 26...and plug it in. Works perfectly fine. it's on 3d hybird instead of simple hybird now...

Tsx536

Cool man! Where's the ECU at? Is it on the passenger side?

Abrams

elduderino

Glad you solved that...

ElD, who's back from the hospital and ready to make even more friends...

Tsx536

What happenned Eld? You okay man?

elduderino

Was passenger in a mnor accident that resulted in labyrinthitis... my inner ear's slightly whacked. Goes away over a week or so.

Sorry about the thread-jacking...

tsxXXX

I think this thred was far from jacked.

This info does not really help anyone because you did not include a picture and failed to mention that the wire might not be there. Abrams was able to prove the fact that the wire did not exist.

Now here is the question... Is the circutry there inside the ecu to provide the VSS signal at the pin? I will be intrested if any one can find that out.

Abrams, I give you props for posting pics rather then writing useless info!!!!

elduderino

Don't know what your problem is, dude - I was asking Abrams to confirm if that pin was involved, sounds like he finally did. Your characterization of "useless" info is interesting... I guess if info hasn't been totally verified, it's useless? It's helpful but not definitive... guess you haven't done much installation - this sort of data is invaluable to an installer.

Glad it works.

nguyenzpry

damn...sounds like a war in here....haha I'll post pic first thing in the morning. Anything else while i'm at it??????

tsxXXX

Elduderino I was just stating the fact that if u link to a thread that says I bet it is in the helms manual but give no picture it really makes the information useless. Even after confirmation with no pictures there is a good chance the information is no good because people like to say they did stuff even though they never did. As an installer I only find data that can be verified by pictures proof as valid. Because that that information is helpful in the field.

I have a tsx with a 460 big block stuffed under the hood I would show u how I did it but I have no pics yet maybe I will post them tomorrow

Let’s see all the pictures off you great installs and then we can talk

jiggaman

A war over a wire huh. That's deep.

tsxXXX - dude you need to relax. elduderino has paid his dues in the information dept. on this site more than you ever will. 14 posts on this site and you are already making enemies, you must be the life of the party in your neck of the woods huh.

Ok, can somebody explain what this thread is about? I know what VSS is, but why would the wire being missing in the first place? Does this mean that VSS wasn't on?

tsxXXX

The VSS signal is a wire that outputs a square wave with a frequency proportional to the speed the vehicle is moving at. The reason it is in question here is because the pioneer N1 unit uses it to move the map along if the GPS signal is lost. The problem is that as Abrams pointed out above in the non nav tsx the wire is not even present at the ECU.

Tsx536

Good explanation TsxXXX! I noticed you have been in a lot of the N1 threads lately, are you maybe considering getting one, or are you just doing research to help you do installs?

On a side note, I agree with the others about Elduderino. Eld has really payed his dues in this forum. He has gone out of his way to help everyone including the Noobs....so don't trip off of him.

If there every comes a time when you need help or info he will do his best to help you!

nguyenzpry

Alright people...relax for a second
this is what i did for the VSS wire...i hope the pics are viewable
Remember.....thanks to Abrams for figuring this out
Thanks man

Tsx536

Good stuff man..!! Shit...looks easy..I almost wanna do it here in the parking lot at work right now!! lol...I'll probably do it really soon though!!

Thanks for the pics!!

nguyenzpry

to check and see if it works...go to INFO! at the menu. Then select 3D calibration status...or sumthing like that...Drive a lil while until the learning status turns into 3DHYBRID

nguyenzpry

no problem man....thanks to you for the idea of putting the unit there anyway

elduderino

Good pics.

I would recommend putting a dab of silicone hot glue behind the plug at the base of the wire. It will rip off with no damage if you need to de-install, but in the meantime it will keep the wire in place and make certain it doesn't bounce out and short against the base of another pin (that could be bad).

The silicone hot glue won't actually chemically bond to the plug, but the silicone will mold to the shape of the plug and wires and grab tight after cooling. Don't burn blisters into the end of your finger (like I did last time I was using a hot glue gun: )

nguyenzpry

Thanks for the tips elduderino

Tsx536

I just got my VSS wire hooked up!! I FINALLY feel like my system is complete! Well..for now anyways...haha.

Thanks for the great pictures NguyenzPry !!
I was able to locate the harness and pin very easily based on those pics!!

I just stripped the wire exactly like you and dapped some silicon on the harness like elduderuno suggested!!

I'm now a 3D hybrid in the information screen. Also, in the connection status screen. The "speed pulse" which use to always read zero, increases depending on my speed!

Thanks again Abrams also who originally found out the wire was not present on the non-navi TSX.

Linner

lol a war of wires, u guys are funny...Actually i had tsxXXX do alot the work on my CL-s and my is300, from springs to tvs in my headrest. Thats the only reason he started coming to these boards to give his insight from workin on acuras and he is a mechanic/engineer

nguyenzpry

subject change......

eschamp

Hi,

It's two years later and the pics are gone. Any chance you could repost them?

Just to be sure, these are pics of how you located the VSS wire in a TSX with no nav system, right?

Thanks.

Reach

nguyenzpry isn't active anymore, but TSX536 is. You might want to consider PM'ing him instead, (or someone else w/ an avic).

Sorry I've got navi, can't help you.

Tsx536

Eschamp, Got your PM. The pic on post #1 should clearly show you where on the harness to insert a wire. There is only one empty slot and it's pin #26.

As for the harnesses on the ECU. I believe that the harness you want to unplug is the harness on the far right. So, if you're looking at the ECU plugs from the passenger side footwell area. You want the harness that is on the far right. This is the only harness that matches the pin layouts from post #1. Once you locate that harness, then match it up with the diagram and find the missing wire you need to insert.

Just write back here if you need more help. Good luck!

eschamp

Thanks for the quick reply.

I'm not following you. The pic in post 1 shows an empty slot in the connector. You're suggesting that I can run a wire from where the VSS signal is generated to that slot?

Where is the VSS signal generated??

elduderino

The VSS is generated within the ECU.

But since all the ECUs in the TSX get the VSS within the CAN data stream, there was no reason to bring out the VSS analog pulse wire.

I'd actually be a bit surprised if this still works in 2006 cars...

elduderino

Forgot to say, "VSS" indicates an analog square wave where the pulses correspond to vehicle speed.

Tsx536

Exactly what Eld is saying, the ECU generates a VSS signal output. On the Pioneer N1, the VSS wire is an input, helping tell the navi that the car is moving, and how fast it's going.

eschamp

Are you saying that if I install a device that needs a VSS input -- like an aftermarker nav system or computer -- I'm out of luck?

Tsx536

I would still try using the VSS wire on the 06. On the 04/05 TSX with navi, the VSS wire is hooked up to the navi and I was able to use it for my Pioneer N3 install. I would guess the 06 is the same. The aftermarket navs such as the Pioneer N3, don't necessarily need the VSS input. They can still function without it and rely solely on the GPS antenna. The VSS wire helps to make the navi more accurate, that's all.

elduderino

I'm saying that IF the empty pin is still connected to a trace on the PCB that carries that signal, AND you figure out that we want you to stick a wire in that empy pin slot, that you will then have a working VSS.

eschamp

Oh, I see now! I thought that the signal was coming from the VSS device along that wire TO the connector!! You're sayng that the signal is available on the PC board. Great!

Thanks.
