De 'ECU Diagnose'

De diagnose-led, meestal een rode led op het dashboard, geeft aan dat er electronishe storingen zijn ontstaan. Het gegeven signaal is afhankelijk van de ernst van de storing waarop dan de evt maatregelen dienen te worden genomen .Gaat bv de led knipperen of constant aan bij draaiende motor, dan moet de motor worden uitgezet.Andere,minder ernstige storingen verschijnen pas wanneer men de ECU een 'zelf diagnose' laat uitvoeren.Een aantal keren knipperen van het controle lampje staat dan voor een bepaalde foutmelding.

Hoe zelf ECU fouten uitlezen:

Scooter staat compleet uit. --> Volgas geven en vast houden , contact aanzetten, lampje gaat uit, lampje gaat aan --> gaslos laten

Nu gaat het ECU Diagnose lampje knipperen, tel hoevaak hij dit doet .Kijk daarna bij de onderstaande code's wat deze foutmelding betekent.

Doordat de ECU echter alle fouten bewaard totdat deze word gereset ,kan het wat onduidelijk zijn welke resent zijn en welke van bv een jaar geleden

-Daarom kun je beter regelmatig en/of eerst ressetten VOORDAT je hem uitleest

Hoe zelf je ECU fouten resetten:

Scooter staat compleet uit. --> Volgas geven en vast houden , contact aanzetten, lampje gaat uit, lampje gaat aan --> gaslos laten

Nu gaat het ECU Diagnose lampje knipperen,--> Laat alle aanwezige fouten ,min 4X achter elkaar (niet onderbreken) paseeren

-Oude fouten die 4x zijn gepaseered zullen worden gewist ,en alleen fouten die nog aanwezig zijn worden dus 5x (of meer) vertoond
