U1002 - Lost Communication with Gateway Module (Power Management2)
DESCRIPTION
* The power management control 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 power management bus.
* When the power management control ECU receives a response signal from the ECUs connected to the power management bus, the power
management control ECU recognizes and memorizes that the ECU is connected to the power management bus. Based on this memorized data,
the power management control ECU monitors for malfunctions in the ECUs connected to the power management bus when communicating
with those ECUs. If the power management control ECU cannot receive response signals from the ECUs that have been memorized as those
connected to the power management bus, the power management control ECU determines that a malfunction exists.
