Caution / Notice / Hint
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2024 Lexus UX 250h, 2023 Lexus UX 250h, 2022 Lexus UX 250h, 2021 Lexus UX 250h, and 2020 Lexus UX 250h. However, it is still accessible from the selected car via links, so may be relevant.
HINT:
- If the vehicle is left with shift lever in N selected (parked or stopped) for a long time, the battery cannot be charged. In this case, the SOC may drop below the lower limit and DTC P300000 may be stored. (This is not a system malfunction.)
- When the engine cannot be started, DTC P300000 may be stored because the HV battery cannot be charged.
- Repeated engine start checks may cause the SOC to drop, resulting in DTC P300000 being stored. In this case, charge the HV battery using the THS charger.
- Cranking the engine once causes the SOC to drop approximately 1%.
- Charging the HV battery once (10 minutes) using the THS charger restores the SOC approximately 2%.
- Charging the HV battery using the THS charger takes approximately 10 minutes when the battery temperature is 25°C (77°F) or approximately 30 minutes when the battery temperature is 0°C (32°F).
- The THS charger is a supplemental charging device that enables the hybrid system to start (READY-on state).
- If the result of this inspection is to charge the HV battery, clear the DTCs and then charge the HV battery using the THS charger.
