What do my fault codes mean?

Thanks for the replies guys, yes already checked the usual suspects (pre-tensioner plugs in door posts and the under seat plugs, had that prob on a freelander a while ago) they all seemed fine but cleaned/re-connected them anyway, as per previous post the dash has to come out anyhow to replace some of the instrument back lighting so I'll do this sooner rather than later and check out the 2 srs lights at the same time, - thanks again for your input/help
 
What with Christmas and a bit of working away only just got chance to pull the dash out, Wammers and Datatek your diagnosis was spot on, one of the srs lights was up the chute, all replaced and now no fault lights, bit strange, I sorta got used to it being there, thanks again for the input
 
Which height sensor is fr? Front right, but are you standing in front of the RR or inside? I think ir refers to the passengers front height sensor on a RHD! Anybody know?

Borrow the next doors kids trampoline. Place it behind your car as close as it will fit. Face the tail gate and proceed to bounce on it doing star jumps. When a considerable height above roof of car is achieved. Jump forwards onto the roof in the star position. After landing you should be face down spread eagled on the roof. As you land be careful of your nuts and chin. When you regain consciousness the part of the car your left hand is pointing to is the left front. The part of the car your right hand is pointing to is the right front. I think you maybe able to extrapolate from previous information to which areas at the rear your left and right leg will be indicating. Take a note of this for future reference. ;)

Ha ha ha ha ha ha :D

Instead of a trampoline, you could always use a truck loading dock, reverse up to it and simply run towards the car. No trampolines involved and a better chance of a direct hit :p
 
You guys are hilarious, should be doing stand up! Thanks for the answers. Was about to order new height sensors when the old girl has dropped to the bump stops with the 35mph message. Read faults and this is what it says

2 FR signal incorrect
6 RR signal incorrect
7 Vehicle has moved
2 Cannot lower RL
2 RL Valve stuck closed

So two sensors required, but unsure as to why it " cannot lower RL "? I rebuilt the compressor and block last year. Is it as it sounds and there is a problem with the valve? Or is the sensors causing it to drop to bump stops and giving false/misleading messages?

First thing you need for EAS functionality is high pressure air. Make sure you have air then clear faults and see what you get. Sensors maybe duff. If you have Nanocom you should be able to open and close corner valves with it. Check they click when you do that. This function in EAS Outputs area along with compressor on off etc. .
 
Hi Wammers, cleared faults and started her up , fairy lights on dash and eas fault message but compressor working and went to what looks like normal height. Haven't got Nanocom, just unlock software and lead. Just plugged back in to read codes and this is what it says
2 FR signal incorrect
7 Vehicle has moved
Before the hard fault I would come out in the mornings to find the rear right was at its highest level and the front would be kneeling down! I cleared the codes again and it is sitting at normal height and working properly again! Not sure if it's relevant but the compressor seems to cut in and out a lot.

Front right sensor has a problem. Vehicle has moved means nothing other than it has dropped since last switched off. Sounds like you have a leak.

This EAS fault could stem from corroded connectors in the left hand side kick panel. Get the panel off & check the two white multiplug connectors.

Those faults are spurious as previously mentioned.
 
Thanks for the comments guys , I soldered up the connectors behind the panels left and right inside when I first got the beast. Have done the soapy water trick. I replaced the front air bags last year when I rebuilt valve block and compressor. If the general consensus is a leak I will look again! Could it be the height sensor playing up?

The plug on the N/S A post base is the connection from the height selector switch to the ECU. Even if the sensor has a fault when the EAS switches on every six hours to self level nothing should drop more than 8 mm at a time. A 15 mm drop over 24 hours is acceptable. If one bag is dropping to the bump stops overnight and all the others are not it is more than likely a leak. Check wiring to sensor for contamination, disconnect it and move it through it's range connected to a multimeter, readings should be linear with no glitches. Remove timer relay and see if it still drops, if it does it is leaking.
 
Took the front right height sensor off and checked with a multimeter and all seems ok. On ohms it goes from about 1200 to 1700 without any glitches. Just the timer relay to take out overnight to see what happens. If it drops then from what you say Wammers it must be a leak. Could it be a non return valve? Not closed? Does it have one for each corner? Take it they are part of the valve block that I rebuilt, so maybe I put it back together wrong? No wiring contamination at plug or socket. I can't hear or see any leaks with the soapy water test. Front bags were renewed last year.

FR & RR signal incorrect will be height sensors or corroded connectors. Check the connectors behind the panels in front of the front door jambs as well as the ones on the sensors. You may need to replace the sensors.
The other 2 messages are likely to be low battery voltage.

To save me trawling through all the threads hoping to find some pics of the location and method to find and clean the connections next to the door jambs, can you direct me to a description, youtube link, etc please. I've got an intermittent RR signal incorrect fault that is driving me nuts. Thanks.

In the footwells, at the bottom of the A posts you will find a plastic panel. Remove these and there are the white block connectors.
