Kill-switch for electronic nannies

[olyelr]

Abs is the one that I cant stand. It's also the only one I have to deal with. Tomorrow I'm going to measure resistance across the abs sensor and see if I can Bypass the abs system and unplug the abs pump. I was talking to an old timer Chrysler mechanic and he thinks it might work and keep the comp happy.

Edit;
Also this is my other thought. Make sure the abs system loses power right when it kicks on

Gotchya. So essentially you would leave it all connected and in working order, but when the ABS is supposed to suddenly kick on you would have something connected to the system that would shut the power off to it? That what you are saying? Sounds like that would be a difficult thing to do.

No it should actually be easy. Yes to what you described. The abs fuse is what a 30amp? Well it only kick in to that kind of draw when the pump kicks on. For the rest of the time it draws just enough power to keep the sensor running. Remember this is just theory. I need to try it to find if it works but I will attempt to read current draw when the truck is running. My thought is installing a 5-15amp auto resetting circuit breaker then when the pump kicks on it would act like a blown fuse. Sure the lights come on. But when you restart the truck the breaker closes and off you go again. Again. Theory. Also going to see if I can find the sensor resistance values and see if there is a way to trick the whole system to just reading the rear sensor. Since the rear is the one used for the speedo. I've broken a front sensor line and the speedo keeps working. Ripped off the rear sensor once and no speedo.

I would be extremely careful about implementing this approach. Think about what the ABS pump is doing - it's re-pressuring your brake system after a pressure release to allow the wheel(s) to turn again. If your system is still able to release pressure but can't re-pressurize, then you lose braking ability.
Just have to hope that the system won't release pressure to all four wheels at once - so you have at least some braking.

I and others used to bypass the system in the 99-2001 years. The pump could be removed or bypassed as it defaults to open system regardless. It should act no different than pulling the fuse. But I don't disregard your advice. That's why my testing is all done here on the farm.

[Bill2014]

When you pull the ABS fuse, the ABS system will not release pressure (we have all seen that)

But, If you have a lower amperage auto resetting "breaker", it may still release pressure and trip on re-pressurizing.

[nts007]

Well it would be no different than the fuse popping. The circuit breaker shouldn't reset until all voltage is gone. So truck off. But I don't know. I need to grab the amp draw from the system

I must have a special truck because mine has driver controlled/operated hill decent.

Alright update on the abs. The computer sends a amp burst through the 40amp fuse to test it. It's a brief second. The burst is on average 6.3 to 6.8 amps. Then the draw drops below what I can read. My multimeter nomaly has a 10amp fuse but I replaced it with a 5 amp. So my theroy still is that after the test the computer just needs to see a connection. I had the wife push the brakes too and the amperage never came up. It should only come up when the pump kicks in. And if the pump loses power it does not affect the brakes and do weird stuff. It defaults to closed state which is what it rests in. Mechanical spring return. So in essence by tripping the fuse the instant it draws power will disable the pump and throw the abs light. Restart the truck and a circuit breaker should reset and give the computer an 'all good" signal and no light. Here's a quick vid. I'm going to make this work today and go for a drive.

Unfortunately I only have a 20amp circuit breaker so I'm going to use a 5amp fuse to test this out. See if the fuse pops and what happens

you go man, cool idea!

ABS works very well in my truck, I only want to override it for off road purposes.

[nts007]

I got it boys!! Test one two and three all popped fuses. Test 1 was a 5amp. Key on it popped. Test 2 was a 7.5amp. Key on it popped. Test 3 was a 10amp. Key on it popped. Then 15amp... Key on. No problem. Alright took it for a drive. Hammered brakes on the driveway. Abs kicked on for about a second then it popped the fuse and I got full braking power. Love it!! I tried my 20amp circuit breaker but it wouldn't trip like the 15 amp fuse. I am going to buy a 10amp and 15 amp breaker and try those when I get to the city. But there is the magic number. Here is a vid of my 3rd test with the 15amp fuse

I would bet for those that want a manual control then a switch in the cab would do the same thing. You could also get one of those resettable type push button breakers that pop up when they trip and have that in the cab and manually reset. Some of you may like abs that's fine. I have had way too many close calls where I've had to hit the ditch because abs took over my braking power when I had more than enough traction. I drive a lot of gravel and if abs wouldn't have kicked in and let me skid tires I wouldnt have hit deer among other things. I don't know about you guys but I can feel my wheels lock up and I can easily lift braking pressure and feel them let go. Maybe driving habits have something to do with these electronic nannies being installed.

I feel like my truck locks up way too soon. I've never ran the Toyo MT's before so maybe it's the tires? It's too easy in my mind to lock up tires on this truck, I don't know if that is common or not.

From what I have dealt with in my truck, the ABS is WAAAAYYY less intrusive then other vehicles I have driven. The only time it has pissed me off is when off road.

[nts007]

Well abs is really easy to bypass. Throw a relay and switch setup on that 40amp pump fuse and you're good to go. And for me its the only intrusive component I deal with for the most part

Thats just it, though, us guys with newer trucks have all sorts of other bullshit to contend with. But when pulling one of the ABS fuses (either one), they all disappear

[nts007]

Computers. Think they are so smart. Until we pull the plug. Take that skynet!
