Kód HVP_w043 nahlásila vo vozidle jednotka „Vysokonapäťová ochrana“. Písmeno „w“ uprostred kódu ho radí medzi záznamy typu varovanie.
Ochranná jednotka vysokého napätia — stýkače batérie, meranie prúdu a bezpečnostná slučka HVIL, ktorá rozpojí vysoké napätie, len čo sa niekde uvoľní konektor. Kódy sem spadajú po nehodách aj po servisných zásahoch.
Vozidlo upozorňuje, že niečo nie je v poriadku. Ísť sa zvyčajne dá, ale niektorá funkcia môže byť obmedzená.
Takto je chyba pomenovaná priamo vo firmware vozidla. Pri kódoch bez popisu je to najpresnejšie vodidlo, ktoré existuje — názov sám hovorí, čoho sa udalosť týka.
Nasledujúci text pochádza z technickej dokumentácie Tesly a necháme ho v pôvodnom anglickom znení, aby sa prekladom nezmenil význam.
Warn if pack contactors are forced open
Warns if the BMS node is mia on HVI CAN
The BMS node is mia on HVI CAN
The BMS node is not mia on HVI CAN
CAN messages are not received from BMS or other nodes on vehicle
Warns if the HVP detects unintended loss of contactor control (V or I)
The HVP detects loss of contactor power or coil current
Contactor power or coil current is dropped below threshold
The contactors opens unintentionally
Warns if the voltage and temperature readings from primary BMB chain are mia
The voltage and temperature readings from primary BMB chain are mia
The voltage and temperature readings from primary BMB chain are not mia
The secondary bmb chain is used exclusively for voltage and temperature protoection
Alerts if any of the pyro diagnostic has failed or the pyro has blown
One of many pyro diagnostic has failed including the pyro having blown
Clears after all the diagnostic has passed
Sorry, Contactors are not allowed to close.
Warn if pack contactors are not allowed to close
This meta alert will set if any of the reasons for preventing contactors to close (listed in this alert payload) are still present. This alert is always set with an accompanying alert that provides more specific information for the fault.
Pack contactor blocking condition is cleared
While this alert is set, HV contactors will not be able to close. This will prevent drive, charge and 12V support and eventually the 12V battery will be fully discharged and the vehicle will go offline.
The PCS node is mia on HVS CAN
The PCS node is not mia on HVS CAN
CAN messages are not received from PCS node
Warn if FC contactors are not allowed to close
FC contactor blocking condition is cleared
warn if shunt temerature exceeds high threshold value
shunt temperature falls below low threshold value
This is an indication that there could be a high impedance joint and prolonged time at this temp could affect the properties of the manganin
Warn if the CPIL fault is detected
Warns if the HVP detects series arc at FC contactor
The HVP detects series arc at FC contactor
The arc condition is not detected at FC contactor
Warns if the CP version mismatch
HVP cannot trust the CP indication, thus it is not safe to charge
warn if if the thermistor sense line is not connected
This is an indication that shunt thermistor is not in place/missing/bad
Warns if the crash signal is detected by HVP
The crash signal is detected by HVP
The ENS idle siganl is detected on ENS line
Warns if the low voltage battery is below minimum voltage threshold
The low voltage battery is below minimum voltage threshold
The low voltage battery is above minimum voltage threshold
The contactors may not remain closed
A brick voltage is below minimum voltage limit
A brick voltage is below minimum voltage limit for X duration (in seconds)
All brick voltages are above minimum voltage limit
The conactors may open immdediately or pyro fuse may blow
The Gateway node is mia on HVS CAN
The Gateway node is not mia on HVS CAN
CAN messages are not received from Gateway node
Warns if the pack current (discharge or charge) is above max current limit.
The pack current (discharge or charge) is above max current limit.
The pack current (discharge or charge) is below max current limit.
Warns if the pack discharge is above max discharge current limit
The pack current is above max discharge current limit for X duration (in msec)
The pack current is below max discharge current limit
The contactors will open immdediately or pyro fuse may blow
A pack module temperature is above maximum temperature limit
A pack module temperature is above maximum temperature limit for X duration (in seconds)
All pack module temperatures are below maximum temperature limit
The HVP part number may be missing, incorrect, or unsupported
The HVP is unable to initialize parameters related to PCBA configuration
Warns if the HVP detects series arc at pack contactor
The HVP detects series arc at pack contactor
The arc condition is not detected at pack contactor
A brick voltage is above maximum voltage limit
All brick voltages are below maximum voltage limit
Odpíšte ho presne, vrátane písmena a čísla. Odfotiť displej je najistejšie — kódy sa často líšia len jednou číslicou a zámena vedie inam.
Časť kódov zmizne po reštarte obrazovky alebo potom, čo vozidlo necháte pár hodín zamknuté. Ak sa kód nevráti, zvyčajne išlo o jednorazový výpadok.
Jednorazový záznam a kód, ktorý naskočí po každej jazde, sú dve rôzne veci. Servisu veľmi pomôže, keď viete, kedy presne sa objavuje.
Airbagy, brzdy, riadenie a vysoké napätie nemá zmysel vyčkávať. Pri ostatných skupinách sa dá počkať, či sa kód vôbec vráti.
Chybové kódy sú len jedna časť obrázka. Pri vozidlách na TesListe vidíte navyše stav batérie stiahnutý priamo z auta a cenovú kalkulačku, ktorá z aktuálnej ponuky spočíta, čo dané auto dnes reálne stojí.
