Refer to DESCRIPTION
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Warning Indicate |
|---|---|---|---|---|---|
| P0C76-523 | Hybrid 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) |
|
Does not come on | Master Warning Light: 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.
