U1002 - Lost Communication with Gateway Module (Main Body)
DESCRIPTION
* The main body ECU will store this DTC when no signals can be received from the ECUs that have been memorized as those that are
connected to the CAN MS bus.
* When the main body ECU receives a response signal from the ECUs connected to the CAN MS bus, the main body ECU recognizes and
memorizes that the ECU is connected to the CAN MS bus. Based on this memorized data, the main body ECU monitors for malfunctions in
the ECUs connected to the CAN MS bus when communicating with those ECUs. If the main body ECU cannot receive response signals from
the ECUs that have been memorized as those connected to the CAN MS bus, the main body ECU determines that a malfunction exists.
