The attached pic shows how to disable VSC in 2004+ models.

 

Stan, it says you need to connect an SST (Special Service Tool) to those pins. So you would have to take it to a dealer to disable?

 

Since it's only two pins, I would think in this case the "SST" is basically just a jumper wire to bridge the pins - and, it stipulates the system will reset with the engine restarted to you'd have to do it at each startup. It should be trivial to do with a simple switch.

 

"The SST (09843-18040) is a 'special service tool' that looks like a jumper wire with 3 ends. 2 ends are blade terminals and 1 looks likes it plugs into something. Can any Toyota techies out there confirm the SST is just a jumper wire?" - http://www.fjcruiserforums.com/forum...-works-11.html

I've scanned through that thread but didn't see anyone saying it is just a jumper wire. The Toyota FJ Cruiser guys found a connector in the engine bay that controls VSC and they built a switch to disable VSC for offroading and driving through sand dunes.

I might have confused you, I turned it off in my SC430, not my LS430. There is a button in the SC430 to turn it off like the GS do.

 

I read the SC430 part. I was just wondering if it could be done in an LS. According to Steve, it seems pretty complicated and I probably won't attempt to do it.

 

I've figured out what SST 09843-18040 does. One end of the SST always goes to pin 4, CG. The other 2 ends can be moved to create a short circuit among up to 2 other DLC3 pins.

One example is for ATF temperature check for cars with air suspension: "Create a short circuit between CG (4), OPA (11) and TC (13) of the DLC3 terminals using SST (09843−18040)."

Knowing this, you could create your own VSC-off button using an SPST (on-off) switch to jump the pins together in the ON position and to break the circuit in the OFF position.

 

Good you are not confused by me.

Yeah the LS430 is not a car many people want to hoon in, so it make sense that the VSC can't be turn off easily. I personally don't feel the need to do any dount or drifting in my LS430

 

I'm going to have to try that. I would prefer that both the traction control AND VSC would turn off together from the dash switch,but most late model cars seem to work separately,with the VSC not being selectable,like in the new Z's.

On the odd occasion that I push the car hard,I find the VSC to be quite intrusive.

Seeing that it's my only car currently and it's just so slippery outside (it's been snowing here for everyone that doesn't live in crappy-weather MI).... Yeah I don't do things like this in the dry (b/c you will need to be going so fast that a huge accident will follow anyways). VSC just makes everything unpredictable. Sometimes it won't realize I am powersliding and won't intervene at all (just how I like it, very natural feeling). Other times, it will cut in mid corner and I will have to immediately steer so that it agrees with the new direction VSC suddenly set it to (though it does slow the car down so it makes it safer/easier). For the record, I only do this sort of stuff when after a lot of snow and after most drivers have gone to bed at around midnight or so. Call it a break from classes/studying
