Kod OCS1P_w142 zgłosił w aucie sterownik „Rozpoznawanie pasażera”. Litera „w” w środku kodu zalicza go do wpisów typu ostrzeżenie.
System rozpoznawania zajęcia fotela pasażera. Na podstawie masy i pomiaru pojemnościowego decyduje, czy uzbroić przednią poduszkę powietrzną. Kody oznaczają, że auto nie ma pewności — poduszka może więc pozostać wyłączona.
Auto sygnalizuje, że coś jest nie tak. Zwykle da się jechać dalej, ale któraś funkcja może być ograniczona.
Tak błąd nazywa się bezpośrednio w firmware auta. Przy kodach bez opisu to najdokładniejsza istniejąca wskazówka — sama nazwa mówi, czego dotyczy zdarzenie.
Poniższy tekst pochodzi z dokumentacji technicznej Tesli i zostawiamy go w oryginalnym angielskim brzmieniu, żeby tłumaczenie nie zmieniło znaczenia.
The temperature or humidity measurement is invalid
Communication with the temp/humidity sensor has been lost
Communication with temp/humidity sensor is restored
The sandwich sensor is not calibrated
The seatback self capacitance sensor is low
The passenger airbag installed is not allowed with an OCS with no sandwich
The OCS determines that an incorrect airbag is installed
The passenger airbag is replaced to match the expectation of OCS
The cushion self capacitance sensor is shorted to ground
Adjacent sensor noise detected.
Set when the sensor internal temperature is over 150deg C.
Cleared when sensor internal temperature is below the hysteresis level 10degc below set point
Sensor function will be impaired, park assist features will be disabled.
Invalid communication from SCCM
At least 3 consequitive invalid messages (of same message type).
Clears automatically when messages are received
Some park assist functionality not availble
Overvoltage detected by the ECU
Sets when the ECU supply voltage is > 16V for 10 seconds or more.
Resets when when the ECU supply voltage is <15.5V for 10 seconds or more.
This error is detected by the ECU. Sensor short to GND or short to plus or broken sensor line and all LIN errors
Five consequitive internal errors occured.
As soon as error condition is no longer present (no power cycle required)
This error is detected by the ECU. Sensor dirt can be detected through any or all of these methods 1. high attenuation time 2. constant echos when vehicle is in motion . 3. low attenuation time 4. jittering attenuation time.
Five consequitive samples of blockage condition being set.
Blockage condition is no longer present (no power cycle required)
Undervoltage detected by the ECU
Sets when the ECU supply voltage is < 9V for 10 seconds or more.
Resets when the ECU supply voltage is >9.5V for 10 seconds or more.
Failed to read or write NVRAM.
Failure to read or write NVRAM.
Clears on next normal boot cycle where read is succesful
Default calibration parameters are used.
Invalid communication from EPB
Invalid communication from EPAS
Expected messages from DAS/APP missing.
Messages missing for more than 3 nominal cycle times.
Sensor internal failure occured - like sensor damping resistor error or broken or disconnected membrane error, self diagnosis error or sensor reset or sensor resonator drift
Expected messages from RCM missing.
Sensor supply voltage outside of specificaiton
Park assist functionality unavailable.
Expected messages from DI missing.
Expected messages from ESP missing.
ECU recovered from a SW watchdog reset.
ECU was previously reset due to watchdog event.
Clears on next normal boot cycle
The secondary controller area network (CAN) bus is in the busoff state.
More than 255 consecutive messages must be missing from the secondary CAN bus.
Messages are received on the secondary CAN bus.
No expected impact on vehicle functionality.
Invalid communication from VCFRONT
Invalid communication from DAS/APP
Expected messages from EPAS missing.
Invalid communication from ESP
CRC of the calibration block in D-Flash mismatched.
On boot, the CRC of the calibration block does not match.
Requires a 12v reset and the fault condition to be cleared
The default calibration is used.
Expected messages from EPB missing.
The calibration block in D-Flash is missing or not available
On boot, the calibration block cannot be read.
Expected messages from SCCM missing.
Hardware watchdog not pet within a specified time.
Clears automatically as ECU will reset
Park assist functionality not availble
Expected messages from VCFRONT missing.
Invalid communication from RCM
RAM/ROM failure on startup, NVM corruption and ECC failure. (ECC Failure DTC, memory failures, checksum failure for appication)
Requires a 12v reset, and the fault condition to be cleared
Park assist features are unavailable
PCS DCDC LV bus voltage reading differs from VCFRONT LV bus voltage reading by an excessive amount
DCDC converter low voltage bus voltage sensor mismatches front vehicle controller's sensed value on CAN for more than three seconds
DCDC converter low voltage bus voltage sensor matches front vehicle controller's sensed value on CAN for more than 500ms
Inability to precharge HV bus, inability to support 12V system, inability to drive
PCS DCDC timed out attempting to precharge HV bus
DCDC converter timed out when attempting to precharge HV bus
DCDC converter state machine clears faults
Charger's input voltage sensor cannot lock the AC input waveform when commanded to start AC charging
Charger phase state machine clears faults for phase
Reduced AC charge rate or inability to AC charge
PCS DCDC detects pack voltage is higher than the safety threshold to continue its operation
DCDC converter detects that high voltage bus voltage exceeds overvoltage threshold
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.
Część kodów znika po restarcie ekranu albo po kilku godzinach postoju zamkniętego auta. Jeśli kod nie wraca, zwykle był to jednorazowy zanik.
Jednorazowy wpis i kod pojawiający się po każdej jeździe to dwie różne sprawy. Serwisowi bardzo pomaga wiedza, kiedy dokładnie się pojawia.
Przy poduszkach, hamulcach, układzie kierowniczym i wysokim napięciu czekanie nie ma sensu. Przy pozostałych grupach można poczekać i zobaczyć, czy kod w ogóle wróci.
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.
