As the canbus is terminated behind the instrument cluster I am beginning to think that maybe where the problem is. Loose or bad connection, bad solder joint etc. Just a thought.

when you say "behind the instrument cluster" are you referring to the connection to the IC?

hmm. as i had mentioned i resoldered the IC harness connector. a visual inspection of the board didn't reveal anything silly... although.. i went in there in the first place because of sooooo many "lost comm with IC" codes

Maybe recheck - solder "dags" can be troublesome Embarassed

yesterday was a long workday, and i didn't venture into the garage afterward.

today, i'm taking a part day, and i'll be:

removing, inspecting, and refitting the engine bay fuse box (slightly melted compressor relay socket)
checking the wiring harness behind the FL wheel well liner
chasing after the VDC as apparently it controls the valve operation NOT the EAS
will test ohm on can bus MS pair
i plan to do some further can bus testing after finding this:
https://www.landroversonly.com/forums/f41/...tem-86337/

i welcome any/all suggestions that don't involve paying somebody else to fix it. happy to buy parts/tools.. i found a nifty CanBus diagnostics kit with oscilloscope, but it's $1,000USD...

in my experience of laptop repair, bad solder joints can definitely cause intermittent issue, but physical disturbance of the board/assembly should cause a state change.

i've played tetherball with the IC on harness, not so much as a minor hiccup

no satisfaction thus far.

i've removed and inspected the fusebox under the hood. it definitely is a little melted around the relay socket, but everything beneath looks perfect. doesn't smell foul either.

does anybody have a network topography map of the MS can bus? like which order the components are connected in? i have read on various forums that the bus runs from diagnostic port to IPC, but it would be helpful to know in which order the ECUs populate the bus...

it's been a very busy week and i haven't had much time at all to really dig in, but tomorrow i plan to hoist the car and remove the LH wheels to inspect the cable connections behind the front liner and the main body hardness connections behind the rear wheel. I haven't found anything funky so far...

somebody about 30min away from me is parting out an 06 RRS like mine, so i'm thinking of going to yank a bunch of parts, that way i'm not spending an arm and a leg on the guessing game.

also, contemplating sending the IPC out for refurbishment as quite a few have reported the same issues and resolution in the form of IPC repair.

i have read lots of "yes you can" and "no you can't" perspectives on swapping with a used cluster. has anybody tried that? if i can walk off with this used cluster for dirt cheap, i am equipped to flash my CCF and same software back onto it. i'd love to hear if anybody has any experience in the used-IPC realm.

SUSPENSION WORKING!!!!

well, I sorted the suspension it seems. I went and stripped a bunch of parts off of another 2006RRS today, and I replaced the reservoir valve and the ATC module, and lo and behold, we have liftoff. about 3/4 of the way through rising to off-road height, the sonofabitch went into crash mode...

still have the MS can bus issue to sort out, but it's lifting!

thanks much to all who've chimed in thus far, particularly gstuart.

still looking for ideas on the canbus

cheers

Hi buddy

Happy days you’ve made some progress, which one is the ATC module please, is it the terrain one

Just looked on here , see it’s the hi can bus circuit if that’s the one I’m thinking of

https://blackbox-solutions.com/help/SM129.html

If it goes into off road that can be a faulty height sensor but more than likely needs its height calibrating to ensure it’s height settings are loaded correctly so the height sensors know what height to stop at

Did u have any joy about getting the instrument panel tested plse

Really pleased for you’ve made some progress

Spent a few evenings trying to find some more info but alas nothing new I’m afraid

Plse keep up updated of how it goes, know that’s not much help
