What is the condition?
This Customer Support Program provides coverage as it applies to the Intelligent Power Module
(IPM). The specific condition covered by this program is failure of the Intelligent Power Module (IPM)
located inside the inverter assembly of the hybrid system. This condition is indicated by hybrid
system diagnostic trouble codes (DTCs): P0A94, P324E, P3004, and/or P0A1A that your dealer can
find by use of a special diagnostic tool. If one or more of these DTCs are detected, various warning
lamps on the instrument panel will also illuminate and the vehicle will enter fail safe driving mode.

Q1a:

What is the Hybrid System Inverter?

A1a:

The hybrid system inverter converts high-voltage direct current (DC), stored in the HV battery,
into high-voltage alternating current (AC) for the motor generator. It also converts AC into DC
during regenerative braking for storage in the HV battery.
