Den Code CC_a044 hat im Fahrzeug das Steuergerät „Wandladegerät (Wall Connector)“ gemeldet. Der Buchstabe „a“ in der Mitte ordnet ihn den Einträgen vom Typ alert zu.
Das Steuergerät des Tesla Wall Connector. Die Codes beschreiben den Zustand der Hausinstallation — Steckertemperatur, Pilotsignal, Erdung, Netzspannung. Die Ursache liegt also an der Ladestation oder der Elektroinstallation, nicht am Fahrzeug.
Der häufigste Typ. Das Fahrzeug hat das Ereignis protokolliert und möglicherweise im Display angezeigt. Die Bandbreite ist groß — von einer Kleinigkeit, die von selbst verschwindet, bis zu etwas, das behoben werden muss.
So heißt der Fehler direkt in der Fahrzeug-Firmware. Bei Codes ohne Beschreibung ist das der genaueste vorhandene Anhaltspunkt — der Name selbst sagt, worum es geht.
Der folgende Text stammt aus der technischen Dokumentation von Tesla. Wir belassen ihn im englischen Original, damit sich die Bedeutung durch die Übersetzung nicht verschiebt.
Wall connector relay coils are at an unexpected voltage, usually due to overheating or other damage
Relay coil voltage is out of the expected range for the current state of the relays
Relay coil voltage returns to normal levels
Wall connector requires configuration via the web UI before it can operate
Wall connector does not have necessary parameters configured
All needed configuration items are complete
The Wall connector will not charge vehicles
More than one wall connector is configured as a master on the sharing network
info from manualCC_A022
More than one wall connector configured as a master was detected on the sharing network
Wall connector detects only one master on the sharing network
Wall connctor input wiring temperature too high
info from manualCC_A012
Wall connector input wiring temperature exceeds 100 C
Wall connector input wiring temperature falls below 80 C or user interaction if charging was stopped
Cotactors opened due to measured current exceeding configured unit current limit or sharing network allocated current
info from manualCC_A006
Measured current exceeds configured limit or sharing network allocation by 10 percent + 1 A RMS
Contactors opened for 10 seconds and less than 4 automatic retry attempts or charge cable cycled
Wall connector will stop charging and retry at most three times before waiting for the cable to be cycled
Wall connector internal watchdog timer expired and the unit is about to reboot
A software bug or upset caused the watchdog timer to expire
Condition will clear upon reboot
Charging will be momentarily interrupted
The UHF receiver reset behavior has successfully recovered communication with the UHF receiver
The charge port (CP) has detected a missing control pilot signal while a charge cable is connected, which usually indicates the charge station does not have power. Charging may not start, and it may be necessary to try a different charge station.
info from manualCP_A053
Proximity is detected with no control pilot signal and no digital communications, and the vehicle is not charging.
The charge handle is unplugged, or proximity with either a control pilot signal or digital communications is detected.
Door is closed but prox or pilot are still sensed
The door is detected closed with proximity or pilot detected present
The door is detected closed with neither proximity nor pilot detected
Charge port door assembly may be broken, door may not operate as designed
GB DC charger faulted due to connector issue
info from manualCP_A067
GB DC charger sends stop message with connector faulted bit set
GB DC charging may not start or may be interrupted. Issue could be caused by charge station
Expected user interface (UI) controller area network (CAN) messages are missing. Charge port door may not open when request is made via the user interface (UI) or mobile app.
Charge port (CP) does not receive all expected controller area network (CAN) messages from the user interface (UI).
Charge port (CP) receives all expected controller area network (CAN) messages from the user interface (UI).
Charge port (CP) door may not open with user interface (UI) or mobile app controls.
GB CC1 or CC2 unexpectedly disconnected during charge
CC1 or CC2 is detected as disconnected while in the active GB DC charging state
The door inductive sensor reports the door is closed
Charging may be interrupted unexpectedly, possible damage to charge inlet if live disconnected under load
DC pin temperature has exceeded the maximum allowed temperature for more than 500ms
Charge cable is unplugged or DC pin temperature is irrational
Charging may be interrupted unexpectedly
The charge port DC pin temperatures have entered a region where its thermal foldback limits are dynamically changing
The charge port DC pin temperature hits its active threshold
The charge port DC pin temperature drops 5C below its active threshold
DC charge current may be limited
Silent alert to indicate that the proximity based thermal foldback was detected
The CP has detected that the CHAdeMO adapter has measured a temperature at which charging should begin to fold back
The CHAdeMO adapter reports a temperature that is higher than desired steady state operation
Cleared if the charge cable is disconnected
Supercharging is unavailable because the post is out of service
The Supercharger reports to the vehicle that the post is out of service
The cable is unplugged or the Supercharger reports that it is no longer out of service
Charging will not start at supercharger stall
PlcForward module detected an error has occured
Schreiben Sie ihn exakt ab, samt Buchstabe und Nummer. Ein Foto vom Display ist am sichersten — Codes unterscheiden sich oft nur in einer Ziffer, und eine Verwechslung führt in die Irre.
Ein Teil der Codes verschwindet nach einem Neustart des Displays oder wenn das Fahrzeug einige Stunden verschlossen steht. Kehrt der Code nicht zurück, war es meist ein einmaliger Aussetzer.
Ein einmaliger Eintrag und ein Code, der nach jeder Fahrt erscheint, sind zwei verschiedene Dinge. Der Werkstatt hilft es sehr, wenn Sie wissen, wann genau er auftritt.
Bei Airbags, Bremsen, Lenkung und Hochvolt lohnt sich kein Abwarten. Bei den übrigen Gruppen kann man beobachten, ob der Code überhaupt wiederkommt.
Fehlercodes sind nur ein Teil des Bildes. Bei Fahrzeugen auf TesList sehen Sie zusätzlich den direkt aus dem Auto ausgelesenen Batteriezustand und einen Preisrechner, der aus dem aktuellen Angebot ermittelt, was ein Fahrzeug heute wirklich wert ist.
