Suspension Malfunction??

Hey folks. I have this warning coming up on my F430 dash (see attached photo). The book says "Suspension Malfunction". In fairness, the car was just shipped across the country and the warning was not on when the car was loaded into the trailer. Has anyone seen this before? Any idea how to reset it? Thanks!

I would drive the car 15-20 minutes to see if its something with low voltage in your battery. This way you rule out first easy issues.

 

Thanks. Did try that. Car starts and runs fine. Ran it solid for a good 30 minutes. Re-started and it's still on. Wild guess, but I wonder if the transporter left the key in ignition for 3 days. Think it might be a battery/electrical current issue?

 

• Faulty shock or shock absorber electronic control unit:
• Faulty wiring:
• Suspension ECU fault:
• Worn suspension parts:
• Low battery voltage:

 

maybe disconnect batter with switch/key in the front of the car under the front trunk and see to switch it back on after 10 mins and see.

 

Could be anything from and battery to a valid issue

Get your a good reader like ap200 (gray and white older version) and pull codes and erase if appropriate

 

Pull codes.

 

Well, it won't be a fuse issue. The same fuse which feeds the Suspension ECU feeds the alternator and the E-Diff.

Was it an open transporter? Did rain get in somewhere it shouldn't have?

 

I had this in my 360… the fix was the rear suspension accelerometer sensor… ferr parts hooked me up …. Still working years later.


Need to pull the codes.

 

This. check under panels either side of engine for sensor. Needs a scan to tell exactly which one.

 

So ZERO TroubleCodes on the OBD2 scan, and battery tested fine at 12.46v. Two w arning lights remain on dash. 1. Suspension Malfunction and 2. Washer Fluid Low. (Washer Fluid is FULL). Very weird. Ideas?

What scan tool is that ..it seems it only reads obd error codes ..you need something like I mentioned above posts to get to the Ferrari specific codes

 

Each shock absorber has an electrical plug- check they are connected

 

I use eobd facile to read my 360 ecu’s…

 

Surely any scanner would give you a code? It's just up to us to decode it.

Warning lights with zero faults does seem unusual. Surely a disconnected component plug would generate a fault code?

Did the scanner identify the car automatically or is the display showing your selection?

The Ferrari specific codes are not usually displayed by generic obd readers unless they are causing a check engine light

So not sure what you mean

 

It’s because the reader you are using doesn’t support the suspension codes. Not weird at all. But n the 360, the rear vertical acceleration sensor is usually the culprit. Not sure of the 430 but you need a computer that’s capable of reading suspension codes.

 

I assumed that any OBD reader would pick up all codes generated (It just reads a sequence of data bits and generates a Pxxxx value). i.e. It doesn't have to know which car it is hooked up to generate a code alone.
For example, I don't have a scanner which has a Ferrari 355 selection so I select an Audi or BMW V8. Codes are generated, but they don't always have the right descriptions... so I use the Ferrari description list for the codes generated. I assumed Ferrari just designs the ECUs so that they generate a particular code for a particular fault. Audi may assign that same code to a different fault. Only the P0xxx codes are standard.

Having said that, my OBD port is only wired into one ECU on my F355, the Motronic ECU. I don't know if there is any special data formatting for other ECUs.

(EDIT: Because no one appears to have a proper decoding list for the F355, I use the 360 list. Sometimes it generates codes for items not fitted to my car. I still have a code, however. I just need to figure out what it means on my F355.)

Most generic OBD readers just read the ECU and don't even scan the other ecu's in the Ferrari so that's why you will miss codes

 

Another vote for accelerometer in the engine compartment. I usually dislike throwing parts at something but it's cheap (in a Ferrari sense) and easy enough to just try it IMHO.

 

That is what fixed my car on pointy blocks warning.

 

It truly surprises me that for $60 to buy an ap200 and see exactly what's wrong people rather throw parts at a car...

Don't get me wrong I bought parts when an error points to two or three things and the time to figure that out you buy one of the three and take a chance but we haven't gotten to that point here

 

Don't overlook battery voltage: You stated you have 12.46v static, this does not show voltage when cranking.
When I first purchased my F430 this display would illuminate when first starting but never again on second or third start, new to the product I tested the battery and it static tested perfectly, but when cranking it could drop voltage below 10v which upsets the suspension CU causing this display.
New interstate battery problem solved its been now around 6+ years later no issues.
Also: If there is any CU/harness/ or sensor issue you will have this display even after clearing codes.
Take Flash32 advice and invest in a better scan tool, you will need that data to get accurate diag.
Good Luck!.
Most importantly enjoy your new toy.

 

I had no idea that was a thing and that it could diagnose a suspension fault. . I've never hooked up more than a basic reader to my 360.

Which is funny because I have VCDS HW/SW for my VW and even something for my Ducati 848s. I had the full VIDA DICE set up when I had a Volvo too.
