DTC P0C76-523: Hybrid Battery System Discharge Time Too Long [08/2013 - ]: Description

WARNING: This page is about a different car, the 2014 Lexus ES 300h. However, it is still accessible from the selected car via links, so may be relevant.

For a description of the inverter. Refer to DESCRIPTION .

DTC No. INF Code DTC Detection Condition Trouble Area
P0C76 523 Inverter voltage (VH) sensor offset malfunction
  • Inverter with converter assembly
  • Wire harness or connector
  • Power management control ECU

HINT: 

When the power switch is turned off, the MG ECU applies current to MG2 in a way that does not generate torque, in order to discharge the residual voltage in the inverter. When the hybrid system is normal, the VH value is almost 0 V after discharge. This DTC will be stored if the VH value is more than the specified value after discharge.
