VCSEAT2R_a108_DIF_MIA	One or more of the messages the vehicle controller receives periodically from the front drive inverter (DIF) electronic control unit (ECU) is not received, indicating the DIF ECU may be unavailable (MIA).	One or more of the expected messages from the DIF ECU is not received.	Vehicle speed and power may be limited. Thermal management system features depending on DIF functionality may be limited or unavailable.
VCSEAT2R_a100_CANbus_MIA	More than half of the ECUs on a either the VEH or PARTY bus are missing more than half their messages while the bus should be active.	If 50% or more of the ECUs the local ECUs listens to are MIA, and the local ECU receives from more than 3 ECUs on this bus. An ECU is MIA if more than 50% of its messages are MIA and that ECU is considered CAN active (see specific ECU's MIA alert for CAN active conditions).	Vehicle functionality may be degraded.
