Suspension Fault..Newbie

[domdom]

Does this software tool tell you the calibration values? I am not familiar with that product at all.

It does show the values and allows you to recalibrate to the correct values. Actually, you can calibrate the suspension heights to whatever you desire. BTW, what are the correct suspension heights for normal mode? 3 of my tires are in the 186-188 range.

Using the IIDTool the normal range for calibration values are between 150 and 250. (If I recall correctly). I'm not sure if that is different with the RSW software. The values relative to each sensor matter too.

THat's good to know. If anyone can track that down and post, that'd be great. I've ordered the left rear height sensor and will install as soon as it arrives. Then I'll re-check the codes using the RSW system and let you know what's going on.

There were a few other codes on the electrical side of things. Something about 'low voltage' for cruise control. Sound familiar?

 

[Houm_WA]

Doesn't sound familiar. Say, when you install that new sensor you are likely going to have to re-calibrate the EAS. I hope your user's manual has instructions for that.

 

[domdom]

Me too! I'm looking into it now.

Thanks for the heads up.

Here's the full Results of my last diagnostic done this morning. Let me know if you guys can help me decipher these / trouble shoot.

Thanks a ton!

Greek to me, your best bet is to either talk to your Land Rover Tech or the Support Department of the RSW Software company. I would also try just clearing those out and seeing which of them come back, if any. They seem like "soft faults" to me and I wouldn't lose sleep over them. Latent voltage irregularities and mis-communication on the CANBUS can cause these things and they are inconsequential.

Good thoughts, Houm_WA. I installed a new rear left sensor, re-calibrated the EAS, and then cleared the faults. It seemed to work for about 5 minutes, but after testing different ride heights there is a new fault titled "Left Rear Corner Valve".

Also, It rained perry heavy here the last couple days and I'm seeing some leaking down each of the front air bag side covers. Does that sound weird?

 

[Houm_WA]

Sounds like you could have a leak somewhere...I'm not trying to be a smart a$$. My LR Tech told me (today in fact) that a leaky valve block can generate a fault similar to a bad sensor.

Many things can register as a sensor fault. A shock going bad, a shock leak, etc. Anything that disrupts the normal function of the shock motion can cause a sensor fault. At least if you know which corner it is you can focus the attention. How old are the shocks? Might need to replace them.
