Thread: Suspension Fault Normal Height Only

You can get the new one much cheaper than that from the U.K. About $500AUD delivered if I remember. Even if they charge an hours labout to fit (shouldn't take that long) and update the software it still going to be about half price.

I have been getting intermittent Normal Height Only for about a week now. With this wet weather and reading this thread I was thinking it was probably dryer. Took Graeme's suggestion back in thread and read the fault codes.
C1A31 - Front Left Corner Valve - General Electric Failure - Intermittent.

1 month out of warranty now. Any suggestions where to start wiggling the wires. Bit hard while its intermittent but worth a visual inspection if I knew where to look.
I have reset to see if it comes back. looks like with the Faultmate you could do a bit of diagnostics, lets you see voltage, current, % open etc.

regards,
Gerry

If you have the NAV with the 4x4 display, what I do is call up the 4x4 display and when driving around, watch how the individual wheels display. Often, one wheel will appear frozen or full up or down. If so, that may be the corner where the problem is.

If you can figure out what corner it is, then the problem may be in the conductors to that corner or hopefully, a wheel height sensor. The odds are that it is the wiring, (broken / corroded single conductor), as that is harder to figure out.

If you have a Llams kit fitted then most likely the cause will be a poor connection on one of the sockets in the grey connector at the suspension ecu in which case the loom should be sent to me for adjustment. Reseating the connector may fix the problem but its bound to come back at some time whilst ever the connector sockets aren't tightened. The wires for the 3 front valves occupy the sockets most susceptible to loosing contact due to the poor design of the ecu connector (the retaining clip is off-centre and the shell flexes too much) in conjunction with the ecu mount angle when Llams is fitted to RHD Land Rovers.

If no Llams is fitted then I would suspect the connector at the front valve block, especially if a bull-bar has been fitted and the electrical connector wasn't well seated when the bar was fitted. Additionally, with my ECB bar the loom was exposed near the valve block when fitted according to the installation instructions and would have chaffed if not protected. The front valve block is mounted forward of the front right wheel, accessible from below.

Hi Graeme,

I just installed my LLAMS yesterday. All went withoutproblem. Then when I was driving to workthis morning, I received the “SuspensionFault Normal Height Only” message. Ipulled it all out, the fault disappeared and I went through the installationagain. Again no problems. I put all the panels back and went for a testdrive and frustratingly, the fault returned.

Iwas justabout to write up a description of everything I did to see if you couldtell me what was wrong. I found this thread and thankfully I keptgoing and when I got to the end, I found your post from 2 days ago. Bloody connectors! I went straight down to the car and pushed thewires up into the connectors, to make sure the pins made contact and relief –fault gone.

I must have been putting a bit of downward pressure on thewires in the process of putting the LLAMS control box into my mounting spoteach time. There’s not tension on them,but a bit of wiggling must have made them loose.

Are they likely to come loose again on corrugated roads? Is there anything else I can do to make surethey stay seated properly?

Thanks for a great product – I can’t wait to try it out onFraser Island in a few weeks time.

Cheers

Greg

Greg, the particular connector these days shouldn't give problems if it is pressed right in and wires not subsequently pulled. It needs quite a firm push for the last bit and once done it wont normally work loose of its own accord especially if the joined connectors are stashed amongst other wiring for support. If pushing wires overcomes bad connections then I suspect the connector is not fully home, perhaps only a one end. However if faults occur with the connector fully home then the connector sockets aren't up to scratch so I will swap the loom.

Driving the Savanah Way from Perth last week in our MY08, got the "Normal Height Only" when doing very slow rocky creek crossings. It resets when the ignition is turned off. Cairns dealer replaced the compressor last week (slow to raise error) with the Hitachi uprgade, and replaced the rattling LCA bushes. We had to disconnect the LLAMS for the compressor updates to download.
All great until a slow rocky creek crossing on the Bloomfield Track yesterday. Same error, but now sometimes in conjunction with "Special Programs Not Available". I have put the whole system is back to standard - LLAMS is disconnect and GOE's Emergency Air Up is been removed. I am now back in Cairns trying to get it diagnosed. Technician's laptop is still pointing to the compressor, but it is only 2 days old! He is going to look for air leaks in the morning. I'll get him to reseat the front valve block connector and the ECU connector as Graeme suggests. Any other thoughts or ideas would be appreciated as SWIMBO is stranded up at Cooktown with the camper and no tow horse!

Make sure when Llams is reinstalled that a cable-tie is fitted around the 2 grey connectors (through the wires) near the long end from the off-centre clip. Some of the pins in the grey Llams loom connector weren't really long enough until a new connector was recently introduced. The Llams connector at the ecu was found to not be causing any problems.
