Hello,
I would appreciate any help of letting me know how to turn of the already too aggressive traction on my beloved Lexus 2007 GS450h. I love the car, but the traction control is driving me of the roof! Even when i use the trac off button it just goes back on when it detects spin. I don't mind any method possible to do it, even if extreme. I tried searching, dealer, and came up with null. I tried the old method for the older GS430's but no luck. Is there anyway?
All the best,
Jaff
So my GS 450h, '07, went for a bearing replacement last week. The new bearing installed did not have a working sensor, die to which the car disabled the TRC, VSC, ABS etc. So I think if the ABS wire is disconnected from behind the wheel, wire with jack connected to back of bearing, everything should be disabled. I haven't tried it on my own though, so try at your own risk.
as the title says u need to put it into mantance mode but do so at owen risk as me manual says not for every day driving .
So it is a peddle dance
get in car turn on ign ( push power bottom twice with out for on brake)
while in park press gas peddle twice
then while in Neutral again press gas peddle twice
then back to park and press gas peddle twice
and last step is to start to car by holding the brake down and pushing the POWER button
have fun but at ur own risk
Worked. Best part is, only the VSC and TRC turn off. ABS and all other safety features still remain on! One thing to keep in mind while preforming this is that the car should be on a level surface, otherwise when you shift into neutral, it will start rolling. Happy GS drifting!

Okay so I tried drifting with maintenance mode, however the powerloss was MAGNIFICENT. The wheels did not want to spin at all, no matter how hard I tried. Also, I tried taking out the ABS fuse. Yes, the TRC and VSC disabled, however, my car lost a lot of brake pressure, almost as if it had no brakes at all. Still looking for a realiable method to only turn the VSC and TRC off. Help please!

When i pulled the abs and abs 2 fuses the brakes worked fine for me and there was no loss of power

I tried the fuse pull method again works fine for me no brake or power loss .
anyway well heres another way i found
i removed the yellow wire (removed for testing idea you could put a switch here to temp break it ) with blue (may of been silver) dots from the LH wire joint box (theres two side by side), card number 37 which powers the TRC control ( while this is disconnected also have no cruise ,afs or vgrs) car drives fine gets way sideways even in the dry in sealed road Behind the glove box , bolted just under the vent RHD
in this pic the yellow wire has already been removed . The pic is just to show the card 37 were the wire can be found. I would cut this wire and fit a switch on dash
Put the car in S so that the engine doesn't auto shut off. Brakes act "funny" right as you come to a complete stop. Wouldn't use it in public for obvious reasons.

are you refering to the orange wire next to the green one ? As i dont see a yellow wire with blue dots on the 37 adapter. Or the whole adapter must be removed to fully get rid of the Trc system ?

How does it feel like driving long term with the no TC or VGRS? Does the steering feel OK? Any weirdness with the brakes? I'm very curious
