    The dashboard maintains memory of old errors.

    Engine oil sensor faults:
    The dashboard will reveal oil pressure faults as well as sensor faults. The oil sensor fault is detected with engine stopped and key in on position, if the sensor is not conducting (open circuit). This fault is indicated by lightening the warning “service” that will remain lit also with engine running.
    Abnormal oil pressure is indicated with engine running at an rpm higher than 2000 rpm and the sensor conducting (shorted). In this case the fault is indicated by lighting the icon “oilcan.” In both cases codes are stored in the diagnostic memory of the dashboard.

    By the way, any idea if:
    Are the error codes sent once & then cancelled by ECU to dashboard special "clear" command / looped every x seconds from the ECU to dashboard?/ once on ignition ON etc or whenever?

    Error Code 60, stepper C.A. What does the CA stand for?

    I've never seen the stepper motor on a wiring diagram. Why is this?

    I Guzzi calls it the automatic choke or automatic air. Depends on the diagram.

    These codes are really strange for all the error codes. They mean something to the engineer, but I've never seen an explanation of the codes. It sure would help everyone if the codes could be better interpreted.

    What Guzzi bikes use the "5AM ECUs" ?

    Specifically, does the 2-Valve 2007 Moto Guzzi Norge 1200 USA use the 5AM ECU ?

    Thanks!

    The 5AM was used on all the CARC bikes came in to US.
    The manual is set up w/codes ending up at a specific pin connector usually. Investigate that connector group.
    Stepper has 4pin connector and the only place wires go is brown side of ECU connector. 09,17,18,19. pin on ecu.
    When you are done cleaning pins, work stepper w/software to see if it works properly.
    There are many threads here on operation & diagnosis of the Idle motor(another name they use).

    Wow, plastic stepper is now $721.69 USD list. Should have bought one w/they were $200

    With Guzzi being such a low volume production company, I can only guess that said stepper motor technology is used in other applications. It is manufactured by Magneti Marelli, so could likely be used in automotive applications. With no restrictions upstream of the stepper, it is capable of flowing a fair bit of air (I have spent a fair bit of time experimenting with this set-up), which could be ducted (split) to the intake manifolds of a 4 cylinder engine. Maybe the small Fiats that have been such a big hit in North America could be using this arrangement??

    Let the search begin!
    An affordable replacement from a source other than MG would be a nice find.

    All CARC models the world over use the 5AM ECU, and yes, lots of stuff Guzzi use is common with Fiat. And Fiat prices are generally much lower.

    There was another thread where it was mentioned that Ducati uses the same stepper.

    A few years ago my Jackal needed a new TPS. $350 from MG, $95 from a Ducati dealer in San Diego. Not the Harley TPS which was different, but the correct match for the failed unit.

    A = Active
    M = Memorized

    You also have your wrench displayed indicating a service is due. Perhaps you have already done the service but haven't reset the display?

    To clear this and the memorized errors, turn the selector near the light switch to MODE.

    Enter the MENU function by briefly pressing the selector button in until MENU is displayed. Then select DIAGNOSTICS by pressing the same button again, holding to enter.

    You will be asked for the Service Code (which is 28315), enter by the same method by briefly pressing SET and releasing until the required number is displayed, then confirm the selection by pressing and holding the same button.

    Toggle through to the "RESET ERRORS" selection, press and hold to clear the memorized errors. Note that active errors cannot be cleared, only when the fault is fixed.

    Use the same procedure to get the the RESET SERVICE function. Press and hold to clear the wrench (spanner).
