Central Diff Lock LC100 Stuck On!

Hi,
Can I assume that you locked it for a reason or has it malfunctioned in some way?
You could try to roll forward on a loose surface in nutural activating and deactivating the switch (allow about 3 secs to let the electric motor lock and unlock the CD) but I would say that jacking up the vehicle and letting the "wind up" dissapear as this is usually why it will stay on.
Otherwise crawl underneath and disconnect the plug on the transfer case.
Alternatively do the "7 pin Modification" as detailed on LCool so you can use low range for towing and manouvering without it automatically locking.

Have you checked the fuses or the plug to the low range motor? Its a motor driven change, can you hear the motor trying to change from low to high?

Cheers

Did you put it in 4wd and can't get it back? Jack up a front wheel.
Did it put itself into 4wd? Electrical issue - they 'fail' to CDL locked setup in the absence of power - check your switch connection in the dash(model dependent), check the activating solenoid and make sure they're o.k.

Thank you both for the idea's I will check with the mechanic, I know he did check fuses.

Try disconnecting the battery for 5 mins. CPU will reset upon reconnection. No guarantees but can't hurt.

Thanks Everyone

We left with the mechanic and when they went to work on it the next morning it has righted itself.

Cheers
