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.
One or more of the messages the vehicle controller receives periodically from the Restraint Control Module (RCM) is not received, indicating the RCM may be unavailable (MIA).
The vehicle controller does not receive one or more of the expected messages from the RCM within the expected time frame.
Vehicle functions that depend on the RCM may be unavailable or may not function as expected.
One or more of the messages the vehicle controller receives periodically from the front passenger seat controller (VCSEATP) is not received, indicating the VCSEATP may be unavailable (MIA).
One or more of the expected messages from the VCSEATP is not received.
Front passenger seat features depending on VCSEATP functionality, including seat buckle and heating pad, may be limited or unavailable.
One or more of the messages the vehicle controller receives periodically from the driver seat controller (VCSEATD) is not received, indicating the VCSEATD may be unavailable (MIA).
One or more of the expected messages from the VCSEATD is not received.
Driver seat features depending on VCSEATD functionality, including seat buckle and heating pad, may be limited or unavailable.
One or more of the messages the vehicle controller receives periodically from the onboard charger (CHG) electronic control unit (ECU) is not received, indicating the CHG ECU may be unavailable (MIA).
The vehicle controller does not receive one or more of the expected messages from the CHG ECU within the expected time frame.
Charging may not start or may be interrupted unexpectedly.
One or more of the messages the vehicle controller receives periodically from the 1st row passenger occupancy classification system (OCS1P) electronic control unit (ECU) is not received, indicating the OCS1P ECU may be unavailable (MIA).
