VSC OFF switch install.

[Dirt J]

@AJSDTP I suggest checking the wiring of this switch to make sure its correct. Just because the lights are turning on/off doesn't necessarily mean that the systems are actually defeated.

You may have already read this in your owner's manual, but the way this works from the factory is that all these lights are normally off when driving. The ABS warning light only illuminates if there is a problem with the ABS system. The VSC TRAC warning light and VSC OFF indicator light may illuminate when there is some other trouble code thrown, but the truck still deactivates these systems due to the other non-related codes.

My issue is that when I have the systems turned on they will turn themselves off. If I hit a gnarly pot hole or take a long sweeping curve or even just swerve a bit to dodge something the lights for all 3 systems come on and disengage the systems. I'm struggling to find what may be causing this issue.

Can you re-state this? If you have the systems off, the lights will be on...that is what the lights do: either warn you that there is an issue with the systems (ABS and VSC TRAC) or indicate the system is off (VSC OFF).

To restate it, the switch is disengaged therefore the systems are active and working and there's no lights on. In this state the lights will seemingly randomly come on and the systems are not working. This happens without moving the switch. And I have tested if it's just lights on but systems work. They do not work. I'll have to find where all of the wiring goes and check how stable it is. I guess it could just be a loose ground or something potentially?

I think I got it! I traced the wiring from the switch and it turns out the dingus used wire nuts for all his connections. Took them off and did a solid stable connection and so far with testing I haven't had any issues

This topic has been widely debated on the internet and I'd rather not contribute to the debate here. I'll just say that the VSC system might not operate properly on vehicles with tires or suspensions that are not original equipment from the manufacturer. If the VSC is not operating properly, its function can cause some undesirable behaviors. This may include annoying beep noises, fuel cut, and braking that is not controlled by the driver at times when their operation is not intended. If you are unsure why this mod might be desirable, or you do not encounter these conditions, then this mod might not be a priority. If your vehicle is in good working condition and calibrated and you do encounter these behaviors, then this is a way to avoid them.

My vsc trac trips out cruise control. also on some gravel is come on at speeds it should nto. Maybe its a sensor, but I think it was made fro people who drive like grandpa. Mine does it more on left hand turns ( I am in OZ, RHfor other places), it come son a brakes too hard, and in the wrong time could cause a slide.

Most likely loose wheel bearings, and or shot steering rack bushing and or suspension related.
