eh , people who roll things try too hard or arent paying attention lol , (normally)

 

(btw, the picture in the manual works now..)

You know, actually I found the picture and initial put it up here, but after looking at it closer, it made me do a double take and some thinking. The reason why is because by the schematic, it looks like I've actually installed the jumper in the WRONG position per the service manual, BUT everything seems to be reacting how the documents says it's suposed to react, ie. the VSC blinking.. Until I figured things out, and to keep from digging a deeper whole, I just decided to leave the picture off the thread.

After finally getting some time tonight, I went to the car and double checked the pins I was jumpering. * I was jumpering the WRONG pins *

This is the schematic,

This is the actual view of the service jack, looking at it straight on while under the dash,


INITIALLY, I jumped the the correct pins. Being nervous about jumpering a pin that I wasn't sure of, I didn't turn the ignition all the way, hence not seeing the blinking light, hence thinking I blew something or installed the jumper in the wrong position. With that, I counted 1,2,3,4 from the left (when it should be from the RIGHT), installed the jumper, this time turning the ignition all the way and seeing the blinking VSC and ABS. With that, I was extatic and didn't even look back to reconfirm if I was in the right pins because I was getting the results I wanted!

Until tonight, I went back and jumped the CORRECT pins 4,12 and not 5,13, I found that actually the VSC and ABS blink, just like it did when jumped at 5,13, BUT

now this is a BIG BUT...

The air bag picture was blinking too! Meaning the AIRBAG, along with VSC and ABS are disabled with 4,12.

I again moved the jumper back to 5,13. ONLY the VSC and ABS were blinking!

Well how about that... I just by mistake found a better way to disable the VSC for street use than what was mentioned in the manual. So far it seems ok. Nothing smoking. Car starts. We'll have to see how it drives first. That will be the true test...

 

btw, here's the information I found on the service port that gave me a little piece of mind that I should be fine just adding a jumper,

As you can see, only 7 ports are standardized on all cars for data communication on what the car is doing. Any other pins are manufacture dependent, and are likely used for disabling the car for testing perposes in one way or another. You should be able to disable stuff simply with the serial data communication, but these must just be the quick and dirty way.

Anyways, here's the schematic of the currently used pins by OBD-II on the service port.

 

A little update,

I've had the jumper now on pins 5,13 for a few days now.

What I've learned is this:
1. Pushing the jumper further into the connector will cause the Traction Control OFF light to light and VSC to stop blinking.
2. After a period of time, if the ABS light doesn't stop blinking on it's own (sometimes blinks for just the first ~1-2min), just touching the jumper ever so gently, it'll stop blinking and you'll only have VSC and Traction Control OFF solidly lit.
3. Sometimes turning the car on with the jumper, nothing is lit on the dash for ~30sec-1min.
4. With VSC lit, Vehical Stability Control REALLY IS OFF! ;)
5. Haven't confirmed yet if ABS is really on, but I'm assuming so if it's not lit.
6. Want to test that the logrithmic brake peddle pressure is still there, but haven't tested it out yet. Should still be as I see no reason for that to be disable as I think it's controlled mechanically and not electrically.
What's tipped me off that something might be different is that I'm having more trouble getting the car to rotate while aggresively trailbraking. May just be that the VSC is off and not adjusting the braking on each corner.
7. So far my initial impressions are that the car handles much better with VSC on. I'll know better after I've gotten adjusted to the way it handles.
8. Tires definately start squeeling quicker w/o VSC!
9. Been able to repeat only having VSC and TC OFF, and ABS ON by removing and reinserting the jumper.

Will try and crimp male pins on the wires so they more can make a more firm electrical connection.

Also, I'd like to later run the jumper to a push button toggle switch that I would mount near the side mirror control or under the dash somewhere so I can just easily use a push button to disable VSC and TC.

T-minus ~ 1 week till the track day...

 

I have really put vsc,abs and trac to the test just recently with the great snow we got in Chicago. The vsc wouldn't shut-up while I was drive on the HW. The roads were really bad. the car was really twitchy but the pie cutters did good anyway. The crosswind had the backend all over.

 

Welp, a few days ago I created the wire with gold plated pins on the ends and used that. Fit very firm, but VSC and ABS would just blink very fast. Doubled checked the pins, tried putting it in and out a few times, and with different combinations of with ignition on/off/engine on/off, etc... same results.

Took my wire jumper that was working before, stuck it in and VSC and TC are solidly lit, with some times ABS blinking but a touch of the wire and it stops... go figure..

Perhaps this works on resistance?... Would know better if I used a voltmeter.. No more time to mess with this now. Since it works and I can keep VSC and TC off only, and reliably, has worked now while driving daily for about 1 week or so, I'm going to continue to mess with trying to get my Sparco Torino seat to fit in the car... grrr...

 

get ahold of a local welder/fabricator , pretty easy to do. maybe a lil more than buying a pre-made set but ya know , get ahold of weapon-r 75 bucks for the pair and should be out within a month or so , i believe

 

Well, I confirmed today in the wet that yes, ABS STILL works with VSC and TC disabled. This is just perfect! :D

hotbox05, I've already talked to a few welders/machine shops and nobody will touch it, everybody says to go to a body shop. There's more to the story, but I'll save it for another thread to keep this one on topic..
