4WD Dash Indicator Light

[Tomtwhite]

My 4WD indicator light is “4 Wheel Drive Lock”. What exactly is locked? The front diff? Front and rear diffs? The transfer case?

TIA

The transfer case. You can also see a closed lock on the transfer case on the off-road pages, if equipped.

AWD, or full time 4WD, will have an engaged transfer case but it woundn’t be locked (similar to a differential).

Our 4Runner has a transfer case that can be locked or unlocked. It makes for 5 modes and is pretty awesome. 2WD, AWD-Hi, AWD-Lo, 4WD-Hi, and 4WD-Lo.

I’d love a transfer case like that in a pickup. I do so much dirt road towing that I end up in 4WD more than needed to try and save some tires. AWD would be a better option.

Thanks. But doesn’t the transfer case lock on all typical part time 4WD systems?

Yes. AWD axles are coupled but not locked

Correct.

Full time has some sort of differential within the transfer case. Some are a Torsen style that puts more power tongue rear axle, and some are more similar to a FWD car.

Kind of unusual. Of the 5 PT 4WD trucks I’ve had this is the 1st that says Locked.
Thanks again.
