OBD-II code · Powertrain (generic, extended)
P2AD5 Intermediate System Voltage High
The intermediate (DC-link) system voltage in the hybrid power electronics is above the expected window. Common during regenerative braking when energy recovery exceeds storage capacity.
Is it safe to drive with P2AD5?
The car may go into limp mode (reduced power). Get it diagnosed before a long trip.
Common causes
