The power inverter module, also called the drive motor generator power inverter module, contains two motor control modules. Each motor control modules measures hybrid battery high voltage with several internal sensors. The hybrid powertrain control module 2 also monitors high voltage with several internal sensors. The hybrid powertrain control module 2 high voltage measurement is broadcast over serial data.
P1AEC and P1AED
The motor control modules compare the values in order to verify the hybrid battery high voltage measurement is accurate.
P1AEE and P1AEF
The motor control modules monitors for high voltage that is greater than the system allows during normal operation.
