Rear Diff Lock problem, need advice

[Tiny Howarth]

Tiny, a couple of questions first:
1) is the vehicle in 4L
2) Have you tried driving slowly in a circle or weaving from side to side?

Peter no, quote embarrassed did not have in 4 wheel low, will try the weekend and give feed back later.

My 4.5 can engage the Diff Lock in 4H and 4L. Attached is the diff-lock layout.

Diff Lock.pdf

The vacuum comes fro the engine. It is swished between locked and open with a solenoid valve on the left side of the car via the control in the cabin. It then runs to the actuator in the back. There is an electrical switch on the diff with the actuator. Anny of these can give a problem. Take some compressed air and clean the piping. Q20 the switch and electro/contactor clean the cabin switch.

Good Luck

Thanks for the download

Gents thank you for the feedback, much appreciated, my first default is that i did not put in low range, however is it normal that the ABS light also flashes?

Hi Tiny

Yes it is normal.
The ABS deactivates when diff lock engages.
So ideally, if everything works correctly, the diff lock switch stops flashing once engaged, and the ABS continues to flash.

Gents, happy to say my rear diff lock works fine, low range then engage rear diff lock is the answer, must say i am revealed for being blonde, at the same time i tested the 4 FWD System and Hub all works awesome. Thanks all. but happy.
