I encountered problem with my EAS system it seems after hitting a small roadside flood with the left front wheel.
I received the Kit from Datatek and the following readings came up:

I'm no whizz on these computers can anyone advise what's the next step?
 
must be water thats got into connections to a height sensor or something, not too clued up on the p38 system but i would be trying to check connections in the wheel arch to make sure there not wet.

I do not wish to be offensive but have you pressed the "UNLOCK EAS" button then followed the procedure laid down i.e.swith off, disconnect diagnostic socket and restart ?
 
FL signal incorrect is likely to be water in the height sensor or in the connector. The other faults are a consequence of the incorrect signal. Vehicle has moved can be ignored.
Do an unlock and the re-read the faults, they may clear if it has dried out. Otherwise you may need a new sensor.

Ok thanks TAKdriver. I wasn't sure of the next step and I didn't want to cause any more problems to the system.

I'll try that this evening.

Thank you Datatek. At least I got a communication link between laptop and diagnostic socket. I'll try the unlock this evening. I'm wary enough about delving to much into it in case I end up changing a setting by accident.

I'll spray some contact cleaner around the plug later on,unlock EAS and initialise the process and see how that goes.

You can't change a setting by accident on that screen. However if you do go into reading sensors, write all the presents down before you start playing, or you can open a bag of worms.

As long as you stay away from the calibration tab, you won't change anything by accident.:)
 
I got around to this last night. I discovered the you tube videos linked on the rsw site and found them a great help.
So I went through the procedure and the left front was showing as a fault.
I got in under it and discovered the plug had disconnected from the socket of the sensor.

It seems as I hit the puddle the force of the water bent the guard,forced it against the plug and caused the plug to disconnect.
I gave it a good clean and spray with contact cleaner,readjusted what was left of the gaurd and reset the faults. No fault showed up when I reran the software so of I went for a spin and all is good.
Thank you to everyone who helped me out it was very satisfying doing my first electronic fix.
Now it's back to the big Spanners and hammer. :clap2:
 
Well that is a coincidence Datatek. Are those guards there to deflect water? They are broken now on mine. Those connections are easily parted. If they were wrapped in denso tape it would help keep them waterproof.

Wrapping them in Denso tape would just keep the water in I'm afraid. Coating the plug in silicone grease is my preferred method.:)
 
If you want any advice on how to fix it give me a shout. :D:D:D:D:p:p

The odd thing is that it has failed in exactly the same way but with different fault codes on the same piece of road. It's an up hill steeply cambered S bend on a dual carriage way crawling in traffic to the traffic lights. On the first left hand bend it goes up to wading height, soft fault, on the second bend cranked over the other way it drops to the bump stops. The first time the fault was pressure signal constantly high. It's been OK for 2 weeks until the same piece of road in slow moving traffic. Curious:confused: The sensor is relatively new. Hopefully it's just water in the connector although the road was dry both times.:)

A funny one Keith. Dropping to stops usually means no air. You could always avoid that piece of road. :D:D:D

Plenty of air, rises immediately the fault is cleared:) Unfortunately I can't avoid that piece of road when I go shopping at the moment as the new TGV line is under construction and all the lanes I usually use are closed.
Pretty sure it's the front left sensor giving erratic readings.
 
I must see how that silicone grease goes so. It strikes me that these connections are not really suitable for immersion in water. It's a pity Land Rover didn't use some of the better quality waterproof connections that are available to prevent water penetration.

LR always liked the cheap but overly complicated method of car building.:D

Better still they could have used strain gauge technology for the sensor, mounted them higher up with long wires to a connector located away from water. Trouble is they might have lasted the life of the car and we wouldn't want that would we?

That would never do Keith. Far too accurate and cheap to produce. How would they justify charging up to £145.00 for something you could get from CPC for a couple of quid.
