@Joe90, did you get to the bottom of the fault code 74, I get this one a few time of late, all seem well with the suspension though. If it dont work.......burn it!

If the IId tool cant fix it.......burn the FF.

If the FF cant be fixed......buy a Land Cruiser!

If the LC cant be fixed..............................................BUY a horse !!

Not yet, have temporarily setup a workaround of fixing the EAS in Motorway height.

When I get a moment, planning on stripping down the valve block on the reservoir and checking if the reservoir is full of water. if the one way valve in the valve block is stuck I may be able to get it going again.

2nd hand valve blocks (with no guarantee they are any better than mine) are @ £180 so this is worth a shot. .

So after the last fault, I reset all faults.

Is this a temperature issue? (reservoir pressure static when filling)

Today, temp outside was @ 14 degrees, no fault registered on drive to work. Coldest it has been for several weeks.

Bet it faults on the way home once it has warmed up!

Oh, and when it does fault, there is no "bong" just message display....

No fault when taken out for lunch (24 degrees)

No fault on the way home (24 degrees)

Is it something else (another fault) causing the EAS to fault? Next time I'll run through all the ECUs as opposed to just clearing the lot... .

Very interested in what you find Tim. I did a long run over the weekend with no issues with the ff and the eas, low and behold coming home tonight, message on display, NO bong, I rest and went home, as soon as I turned ignition off bong message up as before, I restarted and did the lock to lock and turned her off, all ok.......till next time
Now do you when you have reset with tool and cleared fault ( mine is 74 fault also) do the lock to lock on the steering?

I have not done the prv yet though. If it dont work.......burn it!

If the IId tool cant fix it.......burn the FF.

If the FF cant be fixed......buy a Land Cruiser!

If the LC cant be fixed..............................................BUY a horse !!

Forgot to mention I put the relief valve back on!

Not been doing any lock to lock work after resetting with IIDTool, not needed afaik... .

Nothing there I can see that might make it chuck a fault other than the LCM one, but I am guessing this fires after the EAS faults. .

Joe have you replaced the pressure sensor in the air reservoir

I had seen somwhere that pressure switch can be problematic, but which is more likely, switch, compressor pump, valve block.....all 3 !
I my case its not the PRV as I have by passed it and getting the same fault code time after time. Code 57 in the LCM and code 74 in eas. If it dont work.......burn it!

If the IId tool cant fix it.......burn the FF.

If the FF cant be fixed......buy a Land Cruiser!

If the LC cant be fixed..............................................BUY a horse !!
