Have a 2005 Land Cruiser and some months ago the AHC off light switched on and off continuously, the control itself not seeming to function; depressing of the button caused the hi or low indicator light to flash before returning to normal, effectively there was no control. Took the vehicle out yesterday and noticed the off light was not flashing and the mode indicator was showing lo setting; drove off and the vehicle took off like a camel crossing the sands. Checked and topped up the reservoir, listened for the pump when trying different modes, dit deaf so cannot say it the pump is running, however judging by the height of the vehicle I imagine it is! Again took the vehicle on a run and again was in the up and down operation and the suspension height was some 20cm from top of tyre to bottom of wheel arch, hot rod style. Parked the car up for a while, 3 hours, an on starting again with the body still elevated was a bit surprised when it lowered to normal height and the off light was again flashing. Drove for about 20 minutes with the handling as normal as ever, no bounce and no concern other than the flashing indicator. Stopped the vehicle and parked up for about 10 minutes, switched on and started up only to notice the indicator had dropper down to lo and the light was out, drove off and again the bounce was back. Any observations and advice that may bring a modicum of comfort here in rural France!
