Righto, moving on from my battery drain issue, I have replaced the battery (again) so it's not that at fault but I have every single module failed in the car according to it but also, everything works just fine(ish).

I could list all of the faults out but you will die of boredom scrolling through so here's a taster:
ACM-Audio System

  • U0159-00 (2A) Lost communication with parking assist control module

  • C1A60-16 (50) Rear left tire pressure sensor and transmitter assembly - General electrical failure - circuit voltage below threshold
  • C1A62-16 (50) Rear right tire pressure sensor and transmitter assembly - General electrical fail
The only thing that comes up on the dash is a suspension fault and guess what, yeah, that's every single component too! According to GapIID even the interior lights aren't working but they are. I will add that as soon as these faults are cleared they all instantly reappear.

I don't have a parasitic drain on the battery and although it was only just over a year old, it wasn't healthy so that and the alternator have been replaced. I've checked earths etc. but I no longer think it's a voltage issue per se, it feels more like it's a Canbus issue (or whatever the 2010 L322 runs on). I could almost ignore it if I didn't get the suspension warning as I may have had this issue for months but not known about it until now.

Any ideas where to start? I feel like something is killing the canbus but I can't think how to find the culprit and equally I don't want to convince myself this is the issue and go headlong down the wrong path. Have any of you seen this before?

If the CAN bus was down, I doubt anything would be working normally, other than that I do not know.
 
Agreed. What is the common denominator here? What goes and checks everything when you turn on the ignition? Is it the BCM? I must have something failed that is common to everything else I wouldn't get the same failure on every module which is all "lost signal/short to ground/etc."

I don't know, just guessing but I suspect your list of faults are phantom faults caused by poor comms so that is where I would start at the OBD connector.
 
Will look up those codes tomorrow, do you actually have TPMS (tyre pressure monitoring system)?
on our winter wheels we don’t and will get a warning on the dash cos it can’t see them.

Do you have a rear lockable diff, probably not.

Your suspension issue maybe the “acceleration“ sensor.

Did you tell it a new battery was fitted?

Have you been in and changed anything by mistake?

J
 
I don't have those things fitted. I haven't changed anything at all and no,I haven't told it that it has a new battery, didn't know I needed to on this one, never seen it as an option.

I think we can ignore the not-fitted items as it is just communicating so poorly that it can't seem to get a read on anything properly. For the sake of clarity though, here is the full list of faults (scroll at speed here!). It feels like this is everything it has/could have:

Have now done a Battery Replacement routine (that was embarrassing). It made 100 yards almost before suspension fault but other than that, no change. Same faults.

I really think that the suspension fault is just the issue it will show on the dash, not necessarily the cause of my problems.
 
Live and learn, everyday can be a school day:).

I will look up some (not all that lot) for you.
Does the dash message just say suspension fault?


J
 
if it was an addressable fire alarm id say you had a rouge device, try disconnecting them one at a time and see if or when you can clear the faults
 
Have you tried just turning on ignition but not starting the car and then clear the faults. See if they all come back doing it that way first.
 
Have looked at the fault codes (for a 2011 but consider the same)
As you have said you cleared and they all came back.
All I can do is agree with those above about the CAN line being broken causing so many comms issues. With all the "U" faults
Some of them say "module needs coding" If you haven't changed any modules, and don't have many of those fault categories, (TPMS, Keyless entry, rear diff).

I will say that I usually ignore the odd U fault, but as yours is throwing up so many other faults.

My take is, if it cant communicate then it cant see all the sensors, or does but cant send it back so you could get the other faults.


J
 
I've started the process of removing all the modules to see which one is causing the bother and decided that the smart move would be to go with the one thing that I know for sure doesn't work, the FBH. It wasn't that but at least it made me remove it so that I can fix that later; every cloud and all that.

I've pulled the amp connectors, sub, bluetooth, parking aid etc. and the fault remains but it does at least know those parts are missing so I can probably rule them out as the rogue device. As I was on call last night and it was a pretty grotty evening I decided I should test the ABS function and I can confirm that works (I'd have e expected a dash warning if it was inoperable but it occurred to me that I hadn't had cause to use that function).

I do want it to be the air suspension module (or any one isolated thing) as I don't mind the car breaking, it's old and well used.

Does anyone have a list of module locations? I'd rather not be guessing as to where everything is and I don't want to miss one.

Side note, it might be the Keyless module but I'll never know as I unplugged that one and then of course couldn't turn on the ignition to see if the problem had gone away :)
 
Also, don't do a generic "scan all modules". Instead read & clear each module separately, and see what responds.

You could also try pulling fuses for some ECU's so they cannot respond, but beware many vehicles have the CAN lines go in & out to the next module, rather than connected in parallel.
