Co oznacza kod BMS_a122

Battery Management System — mózg baterii wysokonapięciowej. Pilnuje napięcia poszczególnych ogniw, temperatury, rezystancji izolacji i dopuszczalnej mocy. To najczęściej sprawdzana grupa kodów przy autach używanych, bo po niej poznaje się kondycję baterii. Kody dotyczące izolacji lub niestabilności ogniw warto sprawdzić jak najszybciej.

Powaga — a

Najczęstszy typ. Auto zapisało zdarzenie i mogło je pokazać na ekranie. Skala jest szeroka — od drobiazgu, który znika sam, po sprawę wymagającą naprawy.

Wewnętrzna nazwa alertu

Tak błąd nazywa się bezpośrednio w firmware auta. Przy kodach bez opisu to najdokładniejsza istniejąca wskazówka — sama nazwa mówi, czego dotyczy zdarzenie.

Co z tym zrobić

01

Zapisz cały kod

Przepisz go dokładnie, razem z literą i numerem. Najpewniej jest zrobić zdjęcie ekranu — kody często różnią się jedną cyfrą, a pomyłka prowadzi zupełnie gdzie indziej.

02

Spróbuj uśpić i obudzić auto

Część kodów znika po restarcie ekranu albo po kilku godzinach postoju zamkniętego auta. Jeśli kod nie wraca, zwykle był to jednorazowy zanik.

03

Obserwuj, czy się powtarza

Jednorazowy wpis i kod pojawiający się po każdej jeździe to dwie różne sprawy. Serwisowi bardzo pomaga wiedza, kiedy dokładnie się pojawia.

04

Przy układach bezpieczeństwa nie zwlekaj

Przy poduszkach, hamulcach, układzie kierowniczym i wysokim napięciu czekanie nie ma sensu. Przy pozostałych grupach można poczekać i zobaczyć, czy kod w ogóle wróci.

Zanim zaczniesz działać na podstawie kodu. Ta strona jest słownikiem objaśniającym, a nie instrukcją naprawy. Tłumaczy, co oznacza dany skrót i czego dotyczy — nie stawia diagnozy Twojemu autu. Ten sam kod może mieć różne przyczyny, a jego znaczenie zmienia się dodatkowo między wersjami firmware. We wszystkim, co dotyczy hamulców, układu kierowniczego, poduszek lub wysokiego napięcia, jedź prosto do serwisu.

Kupujesz używaną Teslę?

Kody błędów to tylko część obrazu. Przy autach na TesLiście widzisz dodatkowo stan baterii pobrany prosto z samochodu i kalkulator ceny, który z aktualnej oferty wylicza, ile dane auto naprawdę dziś kosztuje.
