Disabling electronic traction devices

Hello Forum,

I was just researching some info on traction control devices. My '08 SR5 PreRunner just has mechanical LSD and no electronic traction aids at all. I will eventually buy a Tacoma 4WD but I would hate to buy another '08 just to avoid the electronic stuff. Id like to buy a newer one.

I read this post from "doitright" from the Yotatech forum. He doesn't specify if it's an SR5, TRD O/R, or Sport but it is 4WD.

Has anyone here tried this?

doitrights answer on the Yotatech post:
Yes, it can be turned off permanently. The skid control ECU has an input labelled "LO", which is used to disable ATRAC/ALSD/VSC while the transfer case is set to low range.

Remove the glove box, and find "instrument panel junction box no 2 behind it. It is a white-ish box with 6 plugs oriented vertically.

Find PIN 9 of the THIRD plug from the top. It should be yellow with a black trace.

Clip the wire off, and tie it (harness side, NOT plug/jb side) to negative/chassis. You should be able to find any of several WHITE wires with a black trace anywhere on that junction box.

What this will do, is feed the low range signal to the skid control ECU, which will disable ATRAC/ALSD/VSC in response.

Now I'm not certain, but doing this may cause the skid control ecuto throw an error (and therefore possibly disable ABS along with it). It might expect a 4wd signal to be sent to it along with the low range signal. If it throws an error, then you are also going to have to locate PIN 10 of the SAME plug, which should be LIGHT GREEN with a black trace, and do the same thing with that one.


Now obviously, this presupposes that you have a 4wd, otherwise you don't even HAVE a transfer case. HOWEVER, I don't think that they actually use a different skid control ECUon 2WD units, and they usually stick with the same wiring harness.... so this will probably work on a 2WD anyway. If those wires don't exist on that plug, then you will just have to find the pins on the actual skid control ECU(under the hood, passenger side, close to the firewall with the ABS pump) and do it there. Consult a wiring diagram.

 

I haven't tried this wiring trick to disable the electronic nannies but you can also just pull the abs fuses and it will disable them.
