DIY YAW sensor Switch (how to deactivate stability control)

[Just1nfj]

Hey,
I know there is already a thread on it.
I made a video that explain the same step i invite you to take a look at the original post.
Here :DIY Yaw Sensor rocker switch


There is the DIY video :

I just redid mine and used a factory VDC Off button from a Nissan Xterra. I wanted it to look factory. Since it’s a momentary switch, I had to wire up a locking relay to hold the position while either on or off. It’s a bit messy at the moment, but wanted to prove the concept before I buttoned it all up.

Looking pretty Factory to me !

The Z for me is my Fun car so balls to the walls for going a little nuts on what the inside look like

I like toggle Cap switch ha ha

Where did you get the relay from? I think this is the route I want to take to keep an OEM look.

This is the relay I used:https://www.amazon.com/ELECTRONICS-S...13R61HVNNVXFBJ

I did the same as you, but instead of adding a relay I modify the inside of the switch. Also, Since I have heated seat, I was able to make it light up with the dash.

I use a switch from a Nissan Guest 2004.

Can you explain what you did to modify the switch? It's difficult to tell from the pictures and I'd like to do the same.

Quoting the Quote! Please go into more detail and impart your wisdom

Can you elaborate on how you wired the switch? Really like this idea!

You need to switch to be normally closed in order for this to work. This means the default status of the button when not pressed is a closed circuit (giving power to the yaw sensor) and then when pressed the circuit is opened (removing power from the yaw sensor)

If you look at the photo you can see the metal bit on the bottom and rotate the photo 90 degrees CCW.

I have some diagrams I've drawn but essentially there is a metal tab with two prongs on the switch body (not pictured in the users irl photo but red in the diagram I've made) that contacts those metal leads and gives the switch an open or closed circuit. As the switch comes stock, it is an open circuit until its pressed which will close the circuit.

What this person did was switch the default nature of the circuit to make it normally closed. They extended the lead coming from the bottom of the switch up higher, and shortened the lead that comes from the top, essentially flipping the switches disengaged status from open to closed, and when pressed closed to open.

Diagrams in album here since I don't know how to add them in thread. https://imgur.com/a/1jFPLBh

Can someone please answer this for me.Does applying a switch to the yaw sensor and turning it off have the EXACT same effect as pushing the traction control button off button on the far left part of the dash?

No. The dash button does not turn everything off.

Traction control button only turns off traction control. VDC/YAW detects the vehicle losing control (spinning out, fishtail, etc) and uses the ABS system to try and correct the spin. With the YAW sensor on, it interferes with the car being able to drift.

Thanks guys,I find that my car launches harder with the dash traction control button pressed(traction control off).Will the yaw sensor switch give me even more power on the launch?I am just referring to traction out of the hole,not stability once the car gets moving.In other words,will the yaw switch allow better burnouts over the dash traction control switch.Sorry if this has been asked before,couldn’t find an answer and have always been curious.

I don't think it will but it's been a long time since I read up on it. There are several threads that discuss the issue* and a functional description (plus wiring diagrams, etc) is in the FSM.
