RentAGuzzi Motorcycle Rentals & Tours – Los Angeles CA
  1. Ciao Guest, Happy 2019! Note all of our products and custom bike builds are now on our sister site; You may need a new username and password to get into the new GTM Store system - pending and past order info is available there. NOTE: We are not Amazon, we are a tiny one man operation. Thanks for your patience on orders. GuzziTech is now back to our origins; Enjoy the Guzzi Community Forum and Resources here. There is zero tolerance on personal attacks and off-site links to other Forums or competing products. Note there's decades of Guzzi hands-on experienced help on this site, all whom give endless amounts of their time for free - be courteous. For those who are new here, the owner of this site (Todd - GT-Rx®) has been immersed in Guzzis since 1999. He's raced and wrenched for two-thirds of his life, both Pro dirt-track and road-race, and contributed to Cycle World Magazine from 2000 until 2007. He began Guzzi dyno performance modifying and fuel tuning in 2001, and has been wrenching them full time since 2007. His GT MotoCycles workshop has been open for ~4 years in Orange, CA. We do not have a phone number for this site or GTM, we're online only... do not ask us to call you. Click on the Service tab above for more info or to book an appointment -- it is not a retail shop to visit. If you're in L.A., you can come sample our work via our rental fleet - click the image link above. In a few short years will hit the 20 year mark of providing advice and tech tips for free. Understand that this is a privately paid for website, not a free social media platform littered with ads to help pay for it. Donations appreciated via the Account upgrade (see Site Support section below) or the Donate tab above, which unlocks all of the content here along with the Classifieds, Ask the Wrench sections and our Seasonal discount notices. Thank you for all of the continued support and contributions.

    The dashboard receives from the central computer only actual faults
    Vcc = + 5Volts. Gnd = Ground or Frame C.C. = Component connector (this is my guess)

    ECU Error Code 16 - Air temperature C.C. Vcc
    ECU Error Code 17 - Air temperature C.C Gnd
    ECU Error Code 20 - Low battery
    ECU Error Code 21 - Lambda sensor (O2 Sensor in exhaust)
    ECU Error Code 22 - Ignition coil 1 C.C. Vcc
    ECU Error Code 23 - Ignition coil 1 C.C. Gnd

    ECU Error Code 26 - Injector 1 C.C. Vcc
    ECU Error Code 27 - Injector 1 C.C. Gnd
    ECU Error Code 30 - Injector 2 C.C. Vcc
    ECU Error Code 31 - Injector 2 C.C. Gnd (This is not listed but I suppose that this is the function)
    ECU Error Code 36 - Pump relay
    ECU Error Code 37 - Local Loop-back
    ECU Error Code 44 - Relay starter C.C. Vcc
    ECU Error Code 45 - Relay starter C.C. Gnd
    ECU Error Code 46 - Canister C.C Vcc
    ECU Error Code 47 - Canister C.C. Gnd
    ECU Error Code 50 - Battery high
    ECU Error Code 51 - ECU general
    ECU Error Code 54 - Instrument panel
    ECU Error Code 55 - Autoadaptation Tito I (I have no idea what this is.)
    ECU Error Code 56 - Vehicle speed
    ECU Error Code 60 - Stepper C.A.
    ECU Error Code 61 - Stepper C.C. Vcc
    ECU Error Code 62 - Stepper C.C. Gnd
    ECU Error Code 00 - Unknown


    DSB 01 - Immobiliser fault: key code read but not recognised or key code not read
    DSB 02 - Key not present or transponder broken
    DSB 03 - Immobiliser fault: Antenna broken (open or short-circuit)
    DSB 04 - Immobilizer fault: internal controller fault
    DSB 05 - Fuel sensor fault
    DSB 06 - Air temperature sensor fault
    DSB 07 - Oil sensor fault DSB
    DSB 08 - Oil pressure fault

    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?
