Kalibrering

Etter at ACC-enheten har vært strømløs kjører den automatisk en kalibrering når bilen startes. Dersom ACC-enheten ikke kjører kalibrering automatisk etter at batteriet har vært utladet eller frakoblet må dette gjøres manuelt. Ved mistanke om feil på AC-anlegget vil en kalibrering oftest indikere hva som er galt ved hjelp av feilkoder i displayet.

Kalibrering igangsettes ved å trykke [AUTO] og [OFF] samtidig. Motoren skal være i gang.

Kalibreringsprosedyren tar ca 30 sekunder.

9-5

Etter kalibrering vises antall feilkoder til venstre i displayet og feilkoden(e) til høyre i displayet. Hver feilkode vises i ca 3 sekunder.

9-3 / 900

Etter kalibrering vises antall feilkoder vha. antall stolper i vifteseksjon på displayet og feilkoden(e) i temperaturseksjonen i displayet. Hver feilkode vises i ca 3 sekunder.

This fault code means the ACC software is corrupt, this will require reflashing by a dealer using tech2. Most ACC systems will work normally with this code.

*1) Se feilkode 11. I original dokumentasjon er det oppgitt at brudd i aksel eller løst spjell på høyre side også gir feilkode 8 som for venstre side. Det er observert at feilen gir feilkode 8 for venstre side og feilkode 11 for høyre side. Uklart om dette skyldes oppdatert programvare eller feil i dokumentasjon.

*2) Kan skyldes at spjeldet er ute av posisjon uten at noe er brukket/skadet.

Programmering

Se Owners Manual

Programmering

Av når bilen startes

First, I set up the ACC's memory:
-start car
-press and release AUTO
-press and release OFF
-press OFF and REAR DEF (the one with the rectangle) simultaneously to save; the display will blink to confirm.
-turn off the car

Now the AC should be in the OFF postion when you start the car.
