DTC P0C76-00: Hybrid/EV Battery System Discharge Time Too Long [10/2018 - ]: Description

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.

For a description of the inverter.

Refer to DTC P0D2D-16: Drive Motor "A" Inverter Voltage Sensor(VH) Circuit Voltage Below Threshold; DTC P0D2D17: Drive Motor "A" Inverter Voltage Sensor(VH) Circuit Voltage Above Threshold; DTC P0D2D1F: Drive Motor "A" Inverter Voltage Sensor(VH) Circuit Intermittent [10/2018 - ]

DTC No.	Detection Item	DTC Detection Condition	Trouble Area	MIL	Warning Indicate
P0C7600	Hybrid/EV Battery System Discharge Time Too Long	The inverter voltage (VH) does not drop during discharge. (Discharge: Offsetting of the residual pressure in the high-voltage side after power switch is turned off) (1 trip detection logic)	Inverter with converter assembly Wire harness or connector Hybrid vehicle control ECU	Does not come on	Master Warning: Comes on

HINT:

When the power switch is turned from on (READY) to off, the MG ECU discharges voltage stored in the inverter by allowing current to flow to motor (MG2) without generating torque. When the vehicle is normal, VH voltage becomes approximately 0 V after discharging. If VH voltage exceeds a specified value, this DTC is stored.
