    I see that on occasion. Generally when the battery voltage is a little low or I tried to start it too quickly (not waiting for the dash to completely settle down before starting). Also "Electrical Malfunction" once in a while. I've never noticed any difference in the steering when that light comes on.

    It would be nice to know what that light is telling you-- my guess is it's saying steering ECU failed self test.

    Give it a few start/stop cycles and see if goes away. That's what I have found. Or, maybe it actually is broken?

    Could have been a low voltage issue that caused a fault, and it just needs cleared out? As ever you need to get yourself a tool to scan and clear codes.

    its not obd2 code easy to clear , i have foxwell 510 scanner and autel ap200 both cant clear the code
    selected both option
    – Scaglietti (F137)
    – Scaglietti MY (F137 MY)

    i think mine 2005 is the F137

    I don't have a good answer for you-- mine has always gone away after usually one, but sometimes two or three, start/stop cycles.

    That’s curious; does the Autel connect to the steering module? My autel does on my 2005 612. Maybe the ecu itself is bad, and that’s why you can’t connect to it.

    Do any of the other modules have a fault listed that would indicate lack of communication with the steering ecu?

    If you can connect, but just can’t clear the fault, that’s usually because the fault is persistent, so you’ll need to cure the cause of the fault before it will go away.

    its connecting i see error code C1014 ( WARINING LIGHT MALFUNCTION) doesnt say much .
    i clicked on erase code ( erased suscessful but wont go away )
    i did notice in LIVE DATA
    voltage = 11.6v ( on old and new battery ..)
    this low, NO?

    I'll have a look at what the Ferrari diagnostic help has to say about that specific code. Doesn't sound as if there's a fault with the Autel though; its telling you that there is a fault present all the time. Its a very basic ecu though, so not sure what its self diagnostic capabilities are.

    if i search by generic obd2 for C1014

    C1014 Possible Solution:


    Power Steering Pressure (PSP) Switch Signal Malfunction The PCM counts the number of times vehicle speed transitions from 0 to a calibratable speed. After a calibratable number of speed transitions the PCM expects that the PSP input should have changed. This DTC is set if the transition is not detected. Vehicle towed with engine running Power steering hydraulic concern was repaired but DTC was not erased PSP switch/shorting bar damaged SIG RTN circuit open PSP circuit open or shorted to SIGRTN PCM damaged Check, if possible, if vehicle was towed or power steering service was performed. Observe PSP V PID while checking wires for intermittents.

    I believe what happens is that the different ECUs don't always start in the order that they are supposed to. Most of the time they do, but sometimes they don't, and errors are the result.

    Also, 11.6v seems low to me, but I'm not sure what the spec value is.

    11.6 volts is way low, Don, and that can cause all kinds of spurious electrons floating around.

    TAZ 11.6 in the live data in (steering module)
    The main battery is new and it’s 12.8

    I see, said the blind man.

    I hate to ask and the pros will kick me because it can hurt diagnosis, but did you try a master reset with the battery cut-off switch?

    Annoyingly the diagnostic manual doesn’t list the fault codes against the various fault conditions for the power steering module. Below are the screen shots for all of the possible fault conditions that will register with this module, along with the suggested diagnosis.

    Could be onto something with the low voltage theory.

    Just reading the screenshots above I see that the threshold for low voltage causing an error in the steering module is 10V, so I think you can rule this one out as the cause of the warning light.

    Thank you for screen shots :)

    so its probably something else, not the voltage ..

    That’s a good step forward!

    Also, as an aside, good to know that autel are still developing this product.

    I assume the solenoid valve is on the steering rack itself and is the means by which the hydraulic pressure is varied in the steering system.

    update
    since the battery died first time in over a year, one expert tech suggested to touch ( ziptie) positive and negative
    to Clear ecu FROM stored faults.
    i did, so left it overnight .. charged the new battery
    put them togethher install new battery .. the code still there.. once i turned the key on.. not even started the car
    i did the drive cycle to reset the smog .. still there

    Sounds like something has gone wrong with the solenoid then...

    After a bit of googling and looking at steering racks listed on ebay, you can see the valve is mounted on the rack just next to where the steering column attaches. Ferrari don't sell the solenoid on its own, but its not unreasonable to think you would be able to get something like this and bolt it in:

    https://www.ebay.co.uk/itm/MASERATI-QUATTROPORTE-M139-07-11-4-2-STEERING-RACK-SOLENOID-VALVE/264437615121

    In any case, I would remove the solenoid valve for testing. Apply 12V across the terminals and carry out a visual check that it is functioning properly. Also check the resistance across the terminals; if its infinite, then you have a confirmed bad solenoid (open circuit). If its too low, then you have a short circuit, though I dont have the specs on what the resistance should be.
