The Toyota traction systems were designed to control the vehicle on curves and slippery roads. There effectiveness off road is just a bonus so to
speak.

If the car/truck manufatures could design an ABS system that works off road I would be really impressed. GM has the best just pull the 60 amp fuse in
the engine compartment. That allows the proportioning valve to work where the 10 amp fuse by the drivers dash side doesn't.

The ABS is disabled when you are in Low Range 4WD on the Tacoma. I would have liked it also to not work in 4-Hi on my 2005... It is much much better
on my 2010.
The '05 would almost crash into things as the brakes wouldn't brake well on wet or dirt roads... dealer said that was 'normal' for ABS. The '10 has
been great.
VSC (Vehicle Stability Control) uses TRAC, but has seperate duties and sensors and prevents the truck from spinning out of control if driver
over-correction occurs at speed.
The driver can diable the TRACTION systems if he desires open differential running with free spinning tires... otherwise:
2WD TRAC (limited slip, with engine regulation) helps the truck move from a stop by reducing tire spin.
2WD AUTO LSD (limited slip, without regulation) helps get moving from a stuck. Like Posi-Traction, very helpful for those with 2WD only trucks.
4WD TRAC (limited slip, without regulation) helps keep the truck moving through unequal road surfaces.
4WD A-TRAC (almost no slip) keeps the truck moving over surfaces that would otherwise halt movement.

I am so happy that my Jeep includes none of this MOMMY-tuning from the factory in OHIO. The Honda that I drive occassionally has so much MOMMY
Hen-pecking from the factory, that you cannot make the front tires spin out! BOO!

A spinning tire has no traction my friend (and a rolling stone gathers no moss) 
Don't be affraid of new technology... and as I said, you can turn off the traction controls so you will have just plain old open differentials where
the tires with less traction get the power... plus the Off Road Tacoma still has a locking rear differential.
Spinning tires also damage the terrain, making ruts and increasing erosion... All I can say is don't knock it until you try it. The A-TRAC allows me
to go places with confidence... and that is key as I usually don't go four wheeling in groups like you do, so I need a vehicle that will not break
down or get stuck!

No more All-Terrain tires on a road like this for me!

I would think, Mike Leon Jr. would have used their tractor to scrape the washouts after the winter rains.. But, until a Nomad we know can post details
and photos of the road heading up the mountain from Mike's, it is anyone's guess. The washed out bridges are from accumilated water flow at the base
of the mountains, near the coast... Mikes' is at 4,000 feet, quite a ways up the water flow, damage would be less, as the streams are smaller. For
sure, they can be mud and boulder slides to deal with... as at Rancho Concepcion's road (not too far south of Mike's). |
I'd love to hit that trail. Maybe in May when I have time off. My Rubicon is getting new tires early next year, so with enough support, I wouldn't
mind doing it.
In my Ford Ranger, I slipped past the boulder that blocks part of the route. My spotter (Gretchen) got real nervous since I had open differentials
and near a cliff, I began to lose traction. No more All-Terrain tires on a road like this for me.
This is why I bought the Rubicon with factory lockers (front AND rear) in order to handle sections of Baja trail like this. I also plan on running a
capable Mud-Terrain tire with extreme traction in order that my runs are safe.
