Unplugging transfer case plug to stop diff lock.

[Brad_kosij Member Find all posts View Profile Close Brad_kosij]

So I have done research and for what I can see to stop centre diff lock engaging its either unplugging it or doing the 7 pin mod.

Since I don't have the time for the wiring mod I want to know about unplugging transfer plug and what effect it had on things. I read it leaves things uninformed like abs etc. but does this make it unsafe?

Ill be towing approx 2.4T of car trailer and 4by soon and may need low range to take off (d4d diesel manual) but will unplugging it render it dangerous being i will be running electric brakes and heavy load?

What's your thoughts?

Thanks brad

Why do you want to unplug it?

Right now you sound like a bit of a muppet wanting to unplug it when you're about to tow at capacity...

If you need to tow in low range the trailer is to HEAVY for the car, JMO

The load should be about 2.4T inc trailer.. It's only to take off every now and then to make it easier on clutch.

Why call me a muppet mate? I'm asking the question, I'm still within limits. You sound like a w$&!?3

Exactly. Only time I've ever towed in low range is shifting a broad acre sprayer when I didn't have a tractor free.

I still don't understand why you want to permanently disengage the centre diff? Is there some secret to towing I don't know about?

You shouldn't have to take off in low range.

I have reversed a heavy trailer around the farm in low range but in an auto the centre diff doesn't lock unless you ask it to. I am guessing that is what the op wants to do except on the road and low range will give the clutch less of a hard time. So low range without a locked centre diff to cause transmission wind upl I have to say though it is one thing starting off in low range and another entirely getting back out of low range. My only suggestion is to avoid leaving the rig in a place where you have to slip the clutch to get going even if that means parking away from your house. I wouldn't be leaving plugs undone.

It's not permanent just a temp thing, I can take off as normal but was more to give me the choice if it is steep or stop/start (heavy traffic) to take it easier on clutch

Thanks mjrandom, your right what your saying, I have a 06 GXL so it automatically locks centre diff when you shift into low it's not because I HAVE to but to make it easier in certain situations.

This isn't a regular thing ill be towing, and its not like I'm towing 2.4T around Australia

Changing back from low range to high range will be a struggle though won't it? Probably end up just getting frustrated trying to twin stick it.

You can't 'shift on the fly' like you can with other 4wd's

My hilux I can, just back off clutch in pull in neutral clutch out-in then back in hi range clutch out..

No that is not correct, it depends on whether you have the traction control or not as to how the diff locks. If your transfer lever has only H-N-L then you will have another button to lock the centre diff, this is on the Grandes or lower specs with the right option pack. GXL's and lower without an option pack will H-HL-N-LL on the transfer lever in which case as soon as you select Low range (LL) or Low Locked the centre diff locks.

Its about the only thing I like about the upspec models such as the Grande. This has been discussed before about how to disable the centre diff lock, I know I looked into it and then put it in the too hard basket.

I do remember reading about it but it was a more permanent option, where as I'm looking at weather I can do it this once if its even safe to do so, care to she'd any light in it Andrew or point me in right direction, I have looked but can't find answers to what I'm asking.

Ill look into doing 7pin mod later but as I said its only for odd occasion I'd really want to anyway.. If its a straight no dont touch the plug then I won't if its as simple as that.

Thanks

OK I was referring to my ex 120 GX with option packs and the 150 GXL. Both of which have the separate button.

Isn't the centre diff lock a mechanically operated unit except for those with traction control?

[Guest Close Guest]

In that case, I don't see how you can disconnect the diff lock via the 7pin mod on the OP's manual Prado. The 7pin mod sounds like an electrical mod.

But all that lever does it operate solenoids on the prado I thought? It not like the older cruisers which actually have two sticks to the gearbox.
