Differential Lock Engagement

[Patton]

Is their an easy way to make my rear differential lock engage in 4wd Part-Time Hi or dare I say..... 2 Hi for doughnuts in the snow. Speaking of that, does it have any RPM limits when it is locked.

I'm guessing there is some pretty simple sensor that keeps it from happening unless your in 4wd Lo that could be bypassed. Any ideas? Thanks!

it sounds like you want a grey mod

check on yotatech or ttora.com for more information on this mod.

The locker ECU comes with two built-in safety interlocks. One safety requires you to be traveling below 5mph for the locker to engage (once engaged, there is no speed limit). The second safety requires you to be in 4LO. To disable the 4LO safety, you have to cut the '4WD' line, which is pin #8 (blue/red) on the ECU, and ground it (after the wire is cut, the pigtail running from the ecu is grounded). The locker will now work in 2HI, 4HI, and 4LO.

You've all been a great help, thanks for everything!

Sorry to revive an old thread. Found this, and I'm curious. Presumably toyota has some reason for the "don't drive over 5MPH the with the locker engaged" sticker that's on the driver's side door.

Anyone know what Bad Stuff

No problem, Toyota didn't have a limit on the locker, just for the engagement of it....at least on my 2000. In fact, in 4Lo, you can easily exceed it. I have spent a lot of time in 2WD going up to 40 and 50 and have had the rear wheels spinning at an indicated 90MPH in the snow (while just being stupid). I never had so much as a hickup with it locked.

I could only imagine Toyota putting that on the window because of the potential handling disruption that you could experience with the rear wheels locked together, if you tried to drive around town like that.

Hi hope this helps.

For the same reason you see warnings on hair dryers "do not use in shower".

I'm afraid that's not helpful in the least. What might be damaged and how? or is nothing going to break? Is it just a question of being more difficult to control the vehicle or something?
