Hello MASH,

Ive now been able to turn off the TRC via the procedure I detailed above, ( With car in Park )

But I was unable to turn it off via your procedure while in drive, I must be doing something wrong.

Maybe the foot brake needs to be held on when doing the two park brake operations , If so, that wasnt in your description.

Derek.

Derek, could you please update or modify the steps below since you got it work because if I follow the steps below it doesn't work.

Thanks

1. Make sure the car is in Park and the parking brake is disengaged before you start the car.

2. Start the engine.

3. Engage the parking brake.

4. Fully depress the brake pedal and then release.

5. Fully depress the brake pedal and then release.

6. Disengage the parking brake.

7. Fully depress and hold down the brake pedal.

8. Engage the parking brake, then disengage it (while holding down the brake pedal).

9. Engage the parking brake, then disengage it (while holding down the brake pedal).

10. Release the brake pedal.

11. Engage the parking brake.

12. Fully depress the brake pedal and then release.

13. Fully depress the brake pedal and then release.

Mash,

This is strange, The instuctions above are correct as far as I know, ( It did work last weekend for me )

But now I'm having trouble getting it to work, I suspect it's a timing issue. ( or I'm not holding my mouth in the correct position )

I'll see if I can work it out and let you know.

Derek.

Derek, Im pretty sure they are correct too. Yes you are correct unfortunately it is a timing issue, when pressing the break / parking break you cant be too slow or too fast. When I was at the dealership it took the sales rep 2 times.. first time wasn't fast enough, second time he got it. He wouldn't show me again after the second time :-| and I dont blame him lol.

OK There is a trick too it. After much experimenting.

To TURN OFF TRACTION CONTROL

The Procedure below MUST be completed quickly, less than 30 Secs from my testing.

1. Make sure the car is in Park and the parking brake is disengaged before you start the car.

2. Start the engine.

3. Engage the parking brake.

4. Fully depress the brake pedal and then release.

5. Fully depress the brake pedal and then release.

6. Disengage the parking brake.

7. Fully depress and hold down the brake pedal.

8. Engage the parking brake, then disengage it (while holding down the brake pedal).

9. Engage the parking brake, then disengage it (while holding down the brake pedal).

10. Release the brake pedal.

11. Engage the parking brake.

12. Fully depress the brake pedal and then release.

13. Fully depress the brake pedal and then release.

Good Luck & Drive Safely

Thanks DerekD,

Yes, I think it is a timing issue because I couldn't work it out for a couple of times and then suddently work 1 time and then tried again and it didn't work.

I agree that we need to do it in less than 30secs, I guess.

Yeah, it's a timing thing. I got it on the third go. It's alright once you get used to it. Stupid question but does it affect the VSC system or EBD in any way? Considering the handling can go out the window if you push the car too hard with the TC turned off.

Has anyone tried doing it with Smart Start?

thought u need to have the brake engage to start it with Smart Start. thus braking this sequence and making it not work?

it's 2:30, just got home... saw this post, thought i'd try it.

works perfectly, thanks derek!

took it for a quick run around the streets with it both on and off...

I can't see when i'd actually need it off...

even going round corners hard, there's no point having it off...

if anything your car picks up traction more quickly when you have TC on...

I can see why you'd want it off in a RWD and want to drift...

but (and someone correct me if i'm wrong) there's absolutely no point having it off in a FWD...

unless of course your stuck in mud or something...

I am sure you are 100% correct on this. Apart from being able to HOON around there is very little point at all. I have tried it and even on wet grass the traction control settings are sensible enough for you to get out of slippery situation. I doubt the car would be faster round corners on a track or even at the dragstrip with it off.

If your into drifting then why would you want TCS on!, defeats the purpose.

And dragging, if your serious about going to the strip to drag, burning old rubber to get to the fresher layers and heating them up is a good method to increase your grip... helps the takeoff times and maintains traction when the torque/power builds up, If you *know* how to drag you can achieve better times with TCS off than on, its all about controlling the power delivery in the first few gears.

But to drive on roads, you would be silly to turn it off as its a safety feature for the environment you are driving in. any other acts of turning it off and taking advantage of it being off is plain Hooning and dangerous.

Hoon is wrong? Is there a boundary for entering "hooning" stage? can someone explain to me

No one is really going to do well drifting in an Aurion.

I can't think of a worse car for it FWD single spinner with foot parking brake. Just hopeless.

Drag racing maybe be a bit better but without a LSD the launch with TC off is tricky and with it on it's reasonably controlled and probably hard to do better with it off even with lots of practice. I just found the front wheels spin and bounce up and down something shocking while the other guys drive past you quietly. FWD is not much fun for drag racing. Certainly I am not used to it which is half the problem maybe.

FF cars will corner better and understeer less with traction control on...

p[lease do not ask me to explain... my time is limited

yep, FWD drag takes practice, Ive seen HiPo civics do 12's on the qtr so its not all bad. But naturally a FWD is worse than RWD when we talk about serious power. The natural clockwise body torque when having crazy power means less grip on the front tyres as the weight is pulling backwards e.g. to the rear wheels.

OK I made up a circuit to apply the traction control in a matter of turn a rotary switch from 1 to 11 which can activate the traction control, then back to OFF in position 12.

Still need to test it guy's so this is a DRAFT.

So if I've done any wiring mistake please let me know.

Pictures aren't loading mate, but I get what your are trying to acheive. I was going to do a similar thing with just two dual stage switches but eventually opted for the messier method shown a while back by overriding the speed sensors. If you could fix the links for the diagram you have, I could give it a once over for you. Only thing I'm not sure about would be how much time between on and off the ECU requires to process that you are performing that procedure.

OK I've fixed picture links, I think we have 30 seconds to complete the cycle of disabling the Traction Control.

Anyway I think the hardest part will be will soldering the internal links within the rotary switch so the common rotary over the link between the positions.

      1999 Camry Driver's door locking hatch issue

      It's possible that it could be something fouling or dirt build up, dry, or a broken mechanism, so have a look and give the mechanism some lubrication, most likely though, it'll be the actuator. I found one for a good price on Ebay, $25 delivered: Front Door Lock Actuator Right Side For Toyota Camry 1997-2001 | eBay

      Query about the correct rotors for 2006 ACV40 Camry.

      Hi, I'm looking at a set of front rotors for an ACV40 2006, 2.4L Camry. I got a good price on some RDA's at Sparesbox. However both RDA8112 and RDA7686 show as for my car and I'm wondering what the difference is and if there were changes to the rotors during the model production. So does anyone know which rotor is the correct one? Many thanks in advance.

      It's a simple solution though? Already laying down 60k for a RAV4, so what's another 1k on a phone to make everything work seamlessly? 👍

      Your solution is akin to suggesting that switching to a different car manufacturer would resolve the issue. However, not everyone shares the same enthusiasm for using an iPhone as you do.

      Turboed Corolla Overbuilt?

      that engine will be fine, the rods are the main thing to be concerned about. The 2860 is a decent turbo for the 1zz but in this day and age I'd go for a G25-550. The injectors might be on the small side, we run DW1000's. You need a full length injector, the shorter injectors with adaptors like ID1050x dont fit the 1zz head. You don't need an aftermarket intake manifold, if you do go down that path, avoid the CNC innovations unit, it's garbage. Do the boost control with a MAC valve and control it with the aftermarket ECU of your choice, I use Link stuff on most of my builds with the G4x Storm as the minimum. I also wire a fuel pressure sensor and oil pressure sensor to the ECU in my installs. Use a decent intercooler, the better cores (ARE, PWR, Garrett, Vibrant, Plazmaman, Hypertune) work a lot better than the chinese stuff like Aeroflow. a 450x250-300 fits fairly well with custom end tanks to route the cooler pipes through next to the radiator Don't forget about the clutch and gearbox. These days I like the Uniclutch twinplate, Above 300whp you'll want to think about upgrading the 3rd and 4th gears in the box also with the SSC (Hollinger) gear set and install an LSD of your choice. If you're going to give it a hard time, you'll also want an oil cooler. I like the HKS thermostat type sandwich plates and setrab or mocal oil coolers with -10 speedflow fittings/lines (Chinese AN fittings neck down to a lot smaller internal diameter in their bends, not great for flow) You'll also want to think about brakes, Celica or Sportivo front calipers will bolt on with sportivo discs as a starting point. To have somewhere like Tunehouse do the work you'll want to budget somewhere between 20-40K

      Camry Touring 2010 Fuel consumption 15.2L/100km. Normal?

      I did the mathematics myself regarding costs vs benefits for fuel injector cleaner. I have changed from 91ULP to 95PULP and 98PULP. Price difference can be about 13 -20 cents. Compared to 91ULP, Premium quality fuel should have a better quality additive package designed to have superior engine cleaning capabilities so the engine can perform at their best.

      "Fuel injector cleaner is a waste of money" Only if you by the cheap crap if you use LiquMolly a German Product it does work and you won't waste your Money.

      Camry Touring 2010 A/C Issues.

      Hi Guys, My Camry 2010 Touring just had a regas done on it and the next day for some reason it wasn't blowing cold air but the next day it is and now working with nice cold air BUT every now and then we can hear and feel a buzz for a few secounds and today while my sister took my car I could her like a mild knocking sound when stopped but goes away when driving off. Any idea what this could be and the A/C is always working now for now.
