Well, im at my wits end here and I kinda want to cry. I am hoping that I am overlooking something and once again turning to the forum in a hope and a prayer.

For background here is a very abridged overview:

Truck: 2013 L320 johnson rods, skid plates, full exhaust..ill keep it brief, it's not heavily modified, but weekend warrior status id calls it. Sits up nice and has so go to it and wheels nicely, but im not Overlanding or rock crawling. Pic on left if off-road height other normal

So i have been busy as hell at work and took the plunge and schedule service with the dealer (ill leave them out for now as im trying to get them to own and fix this **** show) for a basis oil change, annual service, and the once over as well as change both pumpkins fluid and the t case as I beat on it a little this summer. A month goes by, I dont hear from them on the scheduled day for pick up, call repeatedly and finally get a reply mid day and they send a guy immediately to pick it up. Great. I call the service guy and ask, do you know when I will have it back, moreover do you know what your doing? (no one ever called to discuss) . Ok so I tell him what I want and that Id likes to talk to the mechanic after he goes over it as im sure all you do, as preventative maintenance is my mantra. Also I throw in an alignment.

Oh, very important fact, 0, I mean 0, dummy lights on when they picked it up, and i scanned it and had two mirror heat faults due to a short i did. nbd.

Spare you the drama.

They tell me they cant do the pumpkins, t case, or . alignment. Former due to the skid plates /(2 days later) and alignment because its lifted. Dont put me on the phone with the mechanic, mentions some suspension fault and I reply yeah it can happen, i have had to adjust it from time to time, chagre me 800 and send the truck back with a driver.....

here is how I got it back..

These are the faults from my idtool:

RLM-Suspension

• C1A27-14 (AF) Compressor circuit - General electrical failure - circuit short to ground or open

The compressor is not turning on at all fyi...In my humble opinion, i think its possible that the compressor died while in their possession, (75 miles with lift) and thye just ignored it and drove the truck back which made all of this compounded and caused more damage, or somehow they screwed the computer/something happened to knock the suspension offline. The delivery guy barley put in park and i noticed the seconde i got behind the wheel and called....and was told that i was informed of a suspension fault and to call tripple a and have it towed back if i wanted them to fix my truck that they would get me an estimate timely. Unreal luck I have eh.

Thank you in advance for any and all help. At this point, im just sooo frustrat4ed and have tried everything gi could get off we/id tool limited knowledge. I got a truck sitting unusable and the dealer says not thier fault etc... I dont want to have to get into a battle with them so im hoping there is something stupid I missed that someone can point out or that I can at least get a little confidence in prognosis/ next steps and the proper fix from one of you gents. SAVE ME

Wow! Can I ask you a question? when was the last time you changed the battery? I mean it is getting cold, batteries loosing capacity as temp drops, may be just may be it just a coincidence and all that dramma due to deteriorated batter, I mean given bunch of horror stories to do with these truck being sensitive to battery condition. Just saying. It seems rather too many issues at once, unless they took it overhauling and rock climbing which is unlikely.

 

[rquinn12]

Thank you for the reply and for your time. I agree and that was my first inclination. The battery was changed last year and i tested it and its running a pretty consistent 14.4-14.6 . Thinking about changing it just to make sure. On that note, I did, however, attempt the reset where you disconnect the battery and fully discharge right when I got it back . That didn't seem to help at all.

Don't know how much pilfering the dealer did, but maybe a ground (earth) wire is now loose?

Late reply but if you have Johnson rods and do not have an sya kit on there when the suspension drops all the way down it will not recover itself and you will get height sensor faults. The sensors move beyond their range of operation. This can probably be resolved by jacking the car up a little front and rear and then do a reset on the RLM. Sounds like they jacked the car up and when they dropped it back down it went to access height. I have seen this offroading before.

Special Ed thanks for the suggestion. I do have Johnson rods so I’m gonna try it today. Basically need to get both ends up the length of the rod right? And then flash the ccf? Or just reset suspension rlm ?

also just thinking would it help to put stock rods on or it’s already damages due to passing sensors and needs reset regardless? Thanks a ton

 

[Special Ed]

Just jack up a bit front and rear and clear the faults. You can also swap the stock rods on and reset the faults. Either should work if thats the issue.

 

[rquinn12]

OK, so I replaced battery, jacked her up and cleared faults and I still got the suspension fault. I loaded live values for the main components and found this...

Anyone care to confirm for me if the compressor reading 0 volts is the cause of the issue or if it is shut down due to the system being in fault mode due to the sensors being passed by?

Im getting there...thank you all for reading and those who have commented and messaged. I need a vehicle back!!!
