Kód DIF_a202 nahlásila vo vozidle jednotka „Menič pohonu — predný“. Písmeno „a“ uprostred kódu ho radí medzi záznamy typu alert.
Predná pohonná jednotka pri vozidlách s pohonom všetkých kolies. Význam kódov zodpovedá skupine DI, len sa týkajú predného motora.
Najbežnejší typ. Vozidlo si udalosť zapísalo a mohlo ju zobraziť na displeji. Škála je široká — od drobnosti, ktorá zmizne sama, po vec, ktorú treba riešiť.
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.
Drive Inverter Warning: Ambient under temperature
Ambient temperature (refer to pcbTemp) drops below lower temperature threshold
Ambient temperature rises above lower temperature threshold
No direct impact. Could damage drive inverter if temperature is continuously too low.
Drive Inverter Warning: High gear lash angle measured
Drive Inverter Warning: Stator sensor 2 bad
Drive Inverter Warning: Stator over temperature
Stator temperature exceeds upper temperature threshold
Stator temperature drops below upper temperature threshold
No direct impact. Could damage drive unit if temperature is continuously too high.
Drive Inverter Warning: Outlet over temperature
DI coolant outlet temperature (refer to outletTemp) exceeds upper temperature threshold
DI coolant outlet temperature drops below upper temperature threshold
No direct impact. Could damage drive inverter if temperature is continuously too high.
Drive Inverter Warning: Phase A peak over current detected in hardware
Drive Inverter Warning: Phase B rms over current
Drive Inverter Warning: Heatsink over temperature
Heatsink temperature (refer to heatsinkTemp) exceeds upper temperature threshold
Heatsink temperature drops below upper temperature threshold
Drive Inverter Warning: ABS CAN node is MIA
Drive Inverter Warning: Torque limited because rotor is too hot
Drive Inverter Warning: no motor speed as encoder irrational and abs mia
Drive Inverter Warning: Loss of motor control
Motors are not responding to DI commands
Drive Inverter Warning: No Stator sensor available
All stator sensors are giving abnormal measurements
At least one stator sensor returns to rational measurements
Drive Inverter Warning: Track A Disconnected
Drive Inverter Warning: Phase B current sensor bad
Drive Inverter Warning: Track B disconnected
Drive Inverter Warning: Phase C rms over current
Drive Inverter Warning: Unit graceful power off triggered
Diagnostic alert for software trigger of mechanical three phase short
Inverter detects a shorted switch. See payload signals for information on which trigger algorithm occurs
Clears when LV power is removed from drive unit or a non-drive/drive cycle occurs
Drive unit may become permanently disabled
Drive Inverter Warning: Phase A peak over current detected in software
Drive Inverter Warning: Hardware latched fault response in an unexpected state
Measured latched fault response does NOT match with expected request from DI
Measured latched fault response matches with expected request from DI
In the event of a sudden LV loss at speed, latched fault response may not match expectations, exposing drive unit to unexpected torque
Drive Inverter Warning: Phase B current offset too big
Drive Inverter Warning: Low flow rate of fluid
Insufficient cooling to the drive inverter is detected
Cooling is sufficient and a drive cycle is executed
Drive Inverter Warning: External torque command error
Drive Inverter Warning: Phase A current sensor bad
Drive Inverter Warning: Phase A current offset too big
Drive Inverter Warning: Motor speed mismatch
Drive Inverter Warning: Outlet under temperature
DI coolant outlet temperature (refer to outletTemp) drops below lower temperature threshold
DI coolant outlet temperature rises above lower temperature threshold
Diagnostic alert for software trigger of mechanical two phase open
Drive Inverter Warning: Power stage applied a safe state
Drive Inverter Warning: Battery over voltage detected in software
HV bus voltage (refer to busVoltage) exceeds upper voltage theshold (refer to busHighLimit)
HV bus voltage drops below upper voltage threshold
Drive Inverter Warning: Battery sensor bad
When HV bus is up, DI measured bus voltage very low or disagrees with BMS reported voltage
When HV bus is up, DI measured bus voltage matches BMS reported voltage
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.
