ABS on this truck is dangerous...

Yeah except to be recalled it has to be seemed by NHTSA a safety issue. The same organization says that ABS will extend your breaking distance in bad condition so in essence what we getting is "Normal" for ABS.

Yeah we been down that road. It happens on stock tires, it happens on aftermarket.
If it was related to tire size people would get that issue more often.
I dotn think anybody will be able to solve this in 100% with out looking into the ABS logic and changing it.
I understand how the problem is happening but not much can be done by us. Toyota has to fix this, and they won't unless there is another class action suit hanging over them.

 

This might be a stupid question, but here it goes...

Probably close to 3 years ago, my ABS module crapped on me and hasn't been working since. And I actually like it that way, because like many of you, I think it's crap. Question is, since I'm not even using the unit, can I completely take it out of the engine bay? I want to put a second battery under the hood and it looks like that would be a good place to put it. At the very least, I'll probably move it like this guy did:

 

You could remove it but:
1 You need to get replacement splitter so the front line powers front brakes and rear line powers rear brakes.
2. You would need to get proportioning valve for rear wheels.

 

If a similar problem is reported by enough people then the NHTSA will investigate it thoroughly. Better to try to get everyone who is having issues to report it and hope they demand a fix to it than be cynical and do nothing at all.

 

See, I don't think that would be 100% true. Even a slight variation can cause a parameter to fall within the requirements for ABS activation. Just a thought I was having mind you. Something to think about.

That is my point. With a larger tire, you DO have a different change in rotational speed when braking. thus the thought that it COULD possibly contribute to a problem.

 

If the Brake Pedal went to the floor that isn't the ABS. Air in the line, Brake Master cylinder etc...

 

Mehhh. I'll just move the abs module like the picture lol

 

Nope, it was the ABS. It only happened the two times. Try taking your '05 off road, have one or two wheels off the ground and press on the brake. The pedal will go to the ground with absolutely no braking!

 

This seems to be the heart of the matter.
I doubt if the design (not reality) was ever intended to relieve all of the pressure.
I mostly off-road in PA, which is rarely flat, and have often had one or two wheels off the ground while descending.
If this were to happen more often, with the number of Tacos, and the hours of wheeling, there would be a lot more stories.
I am wondering if this is a vehicle specific problem with intermittent mechanical problems that the system is not able to compensate for.

 

My last ABS engagement behaved this way too , the pedal slowly went all the way to the floor while I held constant pressure on it , ABS pulse happening the entire time , then it slowly started pushing back against my foot and started returning back up

 

I filed my complaint on March 13, 2014. The Vehicle Safety Hotline is (888)327-4236. Your complaint may be filed by going to https://www-odi.nhtsa.dot.gov/ivoq/

I asked if they would like to examine the vehicle, but they declined. Currently, there are no open investigations for the 2005 Tacoma (http://www-odi.nhtsa.dot.gov/owners...ia.make=TOYOTA&searchCriteria.prod_ids=216309) Only 2 complaints are reported for 'SERVICE BRAKES' problems, but there are 86 complaints for 'VEHICLE SPEED CONTROL' problems. I don't think they will open an investigation with only 2 reports (they did on the 86 complaints, I believe).

 

I wonder if the issue could be with the ABS simply not shutting off when traction is regained. Like ABS should be kicking off after a few seconds but isn't.

Both times it's happened to me the ABS would not shut off while on the brake for a very long time and at very slow speed. When I let of the brake completely for a second ABS stopped. Then as soon as I lightly touched the brake, ABS was instantly in full force just barely touching the brake pedal again, hardly enough to actually even brake the truck.

 

The fact they told you only 2 cases were open pretty much tells us that no one from here is reporting there problem, even though they consider it enough of an issue to cut some wires and disable the system...

 

Actually for the 2005 Tacoma, there were only 2 reports against 'SERVICE BRAKES'. I looked again and found many more under 'SERVICE BRAKES (HYDRAULIC)". I could find nothing listing 'ABS'. Suspecting the problem is related to 2005-2009 Tacoma, I started looking at other years. The 'pedal to the floor' complaint came up quite a bit on the 2006 Tacoma under the hydraulic brake category. With all the complaints, I don't understand why there hasn't been an investigation! Does anyone know how to get this done?

 

Because ABS not slowing down a vehicle is deemed by government "normal" Thats why there is a note that ABS in bad condition can extend braking distance by a lot.
Therefore stupid ABS is stupid.

 

I have a brand new Nissan Rogue, the ABS is great, works awesome, not scary, it is very predictable and i like it. I think it helps. I have a Toyota SCION TC, the abs is very effective, and works very well in snow, ice, rain etc, just like the Nissan Rogue. I have a 08 Toyota Tacoma, the ABS IS ABSOLUTELY F'N DANGEROUS. So bad I refuse to let anyone drive my truck in snow or icey conditions. Straight up, dangerous. My ABS recenly quit working and it's the best damn thing that has happened to this truck.

Oh, and yes, I filed a complaint with toyota the first winter I had teh truck. They acted like I was the only person to ever mention such a thing.

And to the naysayers; this is not a tire thing, this is not a driver thing, this is not a few isolated incidents....this is a PROBLEM WITH THE ABS SYSTEM. You all can back up toyota all you want, and blame the driver, or the tires or whatever you want so you don't have to face the facts. I don't know if they fixed it after my trucks year 2008, but god help the owners who let others drive their trucks in snow and ice. You have to completely change how you are used to driving a typical vehicle on snow. There is nothing SAFE about my ABS system.

 

Seen a 14' tacoma off the road in a ditch this weekend, buried up to the roof in snow. I offered the man & his wife a ride and the first thing he told me was the ABS came on and he completely lost control. Thank god I have an off-road with the ABS killswitch, best mod yet

 

I agree with every word of this, and you do have to totally change the way you drive versus other vehicles.

I'm on my third 2nd gen, and every one of them has been like that.

My FJ did not share this trait. It was above and beyond excellent in the snow, especially in regard to braking.

 

FWIW - I drove in to work this morning after the ice storm that hit last night. My driveway and the street I'm on was a solid sheet of ice as was the parking lot at my office. The secondary streets were mostly ok but with ice patches in shady areas. I'm also on OEM Rugged Trails (granted they're newish with ~2400 miles on them). I kept waiting on the tires to slip and/or the ABS to kick in and cause me to slide off the road but neither ever happened. I spent most of the time in 2wd with occasional 4hi. I drive a 2014 TRD OR if that matters.

 

That's good news! Maybe they fixed or adjusted their flawed ABS breaking system of years past.
