I was thinking the same thing...or salt/corrosion from East Coast weather...I'm starting to lean that way too.
Multiple codes from multiple systems ---- and they are all electrical in basis.
At this point, I'd forget about the Suspension and focus on looking for generalized electrical problems ---- weak primary chassis ground points and / or wider spread wiring and connector issues (corrosion, for example).

Also, and I hate to even bring it up, but are you 100% certain that your car has never been caught in a flood area ? It does not take very much water to do a lot of damage to a car's electrical systems ---- and it often does not show up until years after
Suspension ECU Failure ???
My car is a 2008 GranTurismo Auto w/ Skyhook Suspension.
Went for a nice drive the other day --- about 45 minutes, just easy cruising around and was not driving the car hard at all. When I turned onto my street to head home, only going about 25mph, all of the sudden the car started bouncing / bucking at all four corners ---- felt like all 4 shocks were out at the same time. “Check Suspension” message and Suspension icon light immediately came on.
So, after I limped it into the garage, I got out my scan tool to see what errors were present, and I retrieved the following 4 (active) codes from the Suspension ECU ----
C1201 Right front solenoid valve – Minimum threshold exceeded
C1202 Left front solenoid valve – Minimum threshold exceeded
C1203 Right rear solenoid valve – Minimum threshold exceeded
C1204 Left rear solenoid valve – Minimum threshold exceeded
So, these are all basically the same issue affecting all 4 shocks, which tells me right away, it’s a system wide problem, not a shock problem (no way they could all fail simultaneously).
I’m guessing that “minimum threshold exceeded” means some sort of electrical power fault ---- low voltage, low current, etc. ?
I’ve already had the battery checked thinking it might be weak, but it’s not ---- perfectly good static voltage and dynamic load delivery specs. So, it’s definitely not a battery issue. I’ve also checked the relevant fuses --- they are good.
From what I’ve heard, the Skyhook ECUs do have a history of failing, so I am assuming that is the problem here. But, of course, I hope it might be something else (simpler / cheaper). So, before I go drop a bunch of $$$ on a new ECU, does anyone here have any ideas of what else the problem could be that I should check out first --- wiring short / open circuit, etc. ???
Thanks in advance for your help, folks.

HiR u in bahrain? I am in Al Khobar, would u plz share with me the name and contact # of the workshop that u r dealing with ? I will visit bahrain tomorrow
I changed the shock absorber control with brand new ine and the error is gone
I changed the shock absorber control with brand new one $ 550 and the error is goneDid you ever get the issue / problem sorted out on your car ?
Regards,
David
Congratulations on getting it fixed !I changed the shock absorber control with brand new one $ 550 and the error is gone
May I ask where did you purchase the control unit from ? That is a very good price for a new one. As I am seeing US$1,000+ at suppliers I have looked to so far.
From Eurospares, exactly 452£ + shipping Good luck 😇Congratulations on getting it fixed ! May I ask where did you purchase the control unit from ? That is a very good price for a new one. As I am seeing US$1,000+ at suppliers I have looked to so far.
Thanks. Currently their website has it priced at $1,315 USD ---- so you got a very good deal indeed !From Eurospares, exactly 452£ + shipping Good luck 😇
This was my part # 290747 (Suspension control unit) maybe yours having a different code and priceThanks. Currently their website has it priced at $1,315 USD ---- so you got a very good deal indeed !

Scuderia is $650 on it that’s where I usually get my parts.Thanks. Currently their website has it priced at $1,315 USD ---- so you got a very good deal indeed !
If i understod you wright you are refering to the WHEEL ACCELERATION SENSOR, that part have nothing to do with this susspention control and it is the cause of the error.Scuderia is $650 on it that’s where I usually get my parts.
eurospares is
But the part number he listed is a control unit that sits on top of the shock not the shock ECU
Look it was a long jurney of suffering and try and error until it was over. I lost alot of money and time following wrong assesments from different technisions

It is under the drivers legs and it is the correct one and the cause of the problem, What error code u have
You also said:My code was code 1203

Maserati Part 290747 SUSPENSIONS CONTROL UNIT

The above is for 2010MY GranCabrio which at todays exchange rate $575. Its unusual that the price varies so much for what effectively does the same thing compared to the GranTurismo. I asked the question on the forum before if they were interchangeable and no clear answer so I went for the exact part number replacement for 2014MY GTS Part no 285374 for M145HL at $1250.
As Sock Tucker said this unit is also available on Scuderia and my dealings with them have been excellent with them willing to offer a 10% discount or match the price at the very least....IF you ask :>)
