ESC nearly killed me !

If you put your truck in 4HI you can disable ECS and do your test on that highway if you really want to confirm that is the problem.
Need to hold down the traction control off for several seconds and it will read on your instrument cluster

I believe once you get to a certain speed the full off the automatically switches back to partial off.

I think your correct.
I do recall seeing that happen once and looking down and saying "I thought I just turned you off"

Definitely DO NOT DO THAT!!!

Why not? I've driven 30+ mile's with esp/TCS completely disabled. Granted not in 4-hi.

He's not taking 90 degree turns on the highway, and if it helps figure out the exact problem.
I think ESC will turn back on after a certain MPH though unless you turn it off.
I forgot about that.

He said 4 Hi.
4 Hi on pavement, ESC on or OFF, not good. You know that.

 

[HSKR R/T]

He said 4 Hi.
4 Hi on pavement, ESC on or OFF, not good. You know that.

As long as he's not taking hard turns, and isn't doing it frequently it's not going to hurt anything.

Go 4 Hi, ESC on or off, on pavement and drive. See what happens when you turn.

Bro, did you even read OPs problem?
He's driving on the freeway at "high speed"s

Not good advice. Any turns will cause binding. Will it break something? You try it out and get back with us.

Firstly, you are far, far, infinitely far from one of my Bros.

I did read his issues.

There has been some bad advice given by you.

 

[HSKR R/T]

I've driven in 4-high on pavement before. Truck still works just fine. I run at the drag strip in 4-high and don't flip back to 2wd when hitting turn off at the end.

Can go straight all day long with no binding. Come on man.

Like I said, hit the turn off still in 4-high, and have made multiple passes without ever switching out of 4-high. Do the tires chatter in corners, sure but not destroying anything

Enforcing the idea that 4 Hi, ESC partial or Full Off is not bad turning on pavement is wrong.

 

[HSKR R/T]

So is it ”don‘t flip back to 2WD when hitting the turn at the end“ or “hit the turn still in 4- high”.

Enforcing the idea that 4 Hi, ESC partial or Full Off is not bad turning on pavement is wrong.

Once agains I'm not saying it's something that should be a regular practice, but every now and then isnt going to destroy your truck. Such as troubleshooting for the OP.

The OP is talking 65 -70 MPH turning on the highway on a turnoff.

So tell us how to set this up without destroying his drivetrain or killing someone.

Try it, you might like it.

 

[Ramroo]

Im waiting on how the OP should set this up in 4Hi ESC off on a turnoff from the expressway at 65-70 mph to ”troubleshoot“.

Can he just pull the fuse to completely disable for this test? Instead of just being partial off and in 4 hi?
