Stuck in 4wd

Yes it has vaccum hubs. The metal connector was fractured . When i checked yesterday it was not hanging down. I wonder if the vacuum locked the hubs in , then split from the pressure etc. It's definitely in 4wd. The push buttons do nothing and the 4wd light just flashes all the time.

Try jacking each front wheel one at a time and spinning it. As this points more to the transfer box switch fault.

Just hope it can be sorted. My girlfriend is a pet sitter and has had to cancel all business. It's a nightmare.

I would think its worth trying to short out the vac system and see if you can get the t-box to shift then.

Easy to do.

The vac manifold is below the battery. there is a pair of white wires going into a sensor from the wiring loom on it. unplug this connector, short the two pins.

Try running the engine, then pushing the buttons to swap around the t-box options. clutch needs to be pressed in for 4L.

This shorting trick isolates the vac hub system from the rest of it, allowing you to diagnose if the fault is with the transfer box or the vac hub system. I would bet that its the hubs causing the problem. I believe its necessary for the 4x4 controller to see a closed signal from the vac hub system before it will allow the transfer box to do any swapping of modes. This shorting of wires 'fools' the 4x4 controller into believing the hubs have done as asked, and will then try to move the transfer box as desired.

hope that helps explain how it works

I will try this. Is this the sensor near the tiny air filter. How do I short it, just put a word over both connectors or something. Thanks again!

A wire I meant

There is a plug/socket thing. unplug and hold a wire between the two terminals in the part connected to the wiring loom (not to the part with the blue air filter on it). This is fooling the 4x4 ECU into thinking it has achieved a vacuum, thus allowing the transfer box to operate (hopefully).

The blue filter goes to a connector and the connector to the loom. Just short the loom side then. Will give it a try. If it works what does it say is the problem is?Thanks so much

You mentioned you had a leaking vac pipe near the axle somewhere? this will be the problem ( a leak on the vac system), if this test works and allows the transfer box to shift as desired.

the answer is to fit manual hubs and leave the wiring bypassed as above. easiest and most reliable thing to do

Yes the top pipe on passenger side front wheel was disconnected. I've reconnected it with a plastic hollow t piece as metal one rotten but it has not helped with anything. When pressing the 4wd button originally I heard the hubs click in but light just kept flashing and now it stuck.

So far on the jimny I've put in a new radiator, changed alternator and ps belts, changed difff oil and serviced it but this is the most difficult bit so far by a long way, I'm not great with wires . When its running well it is an awesome vehicle though . I have no electrical knowledge apart from using dialysis machines and life support equioment lik ventilators etc!
