Hi Guys, dont really use the patrol to go 75km to work, but today I did and as I got into the city driving , I notice that the electic diff lock dash light was coming on when I stopped at traffic lights, then went away when moving . I don't why the light is coming on as I haven't touch the diff switch in a long time. any answers will have me cheers Alex
Switch may be stuffed possibly or check the sensor wire on the back of the diff. Maybe thats fell off

30km down the road , the light and alarm came back , pulled over and another "tap tap" and light go's away , just be4 home light comes on . hmmm what could it be ? cheers Alex
Have you pulled the vac hoses off the diff solenoid or checked them for damage? If the vac line to keep the actuator out (disengaged) it could be creeping back a touch just enough to trip the sensor to set the alarms off.
Or there is a possibility that the vac solenoids in the engine bay are stuffed causing the issue by either passing or being seized.
Check to see if there is vac pressure at the diff too while your at it. It wont be a hell of a lot but usually noticeable with a finger over the end.
Stick it in 4L and hit the diff lock switch. Pull one off and see whats getting the vacuum. Then turn it off and see what line has vac then.
You can also play about with it and stick the hose with vac on the other nipple to see if you can hear the actuator and fork moving inside the diff.

? because I never used the diff lock before, hard to tell if it's working going by the dash light , So I'm in low range ,turn on and it flashers , that means it on or something else. in the car manual ,something about ABS in which I have .... please help Alex
Diff lock light will flash until its engaged. Once it is engaged it will stay light solid. Sometimes takes a bit to engage with the factory solenoids. Few slow tight turns left to right usually help engage it. ABS light will flash as it will disable when the diff lock is selected.

Hi Guys , had time today to do some Solenoids checks and both are working as they should. maybe the rear diff hose as they are very hard in rubber wise , e.g. couldn't get them loose ( so tight ) . regards Alex
