DTC U1002: Lost Communication with Gateway Module [10/2014 - 09/2017]: Description
- The hybrid vehicle control ECU stores this DTC when no signals can be received from the ECUs that have been memorized as those connected to the sub bus 11.
- When the hybrid vehicle control ECU receives a response signal from the ECUs connected to the sub bus 11, the hybrid vehicle control ECU recognizes and memorizes that the ECU is connected to the sub bus 11. Based on this memorized data, the hybrid vehicle control ECU monitors for malfunctions in the ECUs connected to the sub bus 11 when communicating with those ECUs. If the hybrid vehicle control ECU cannot receive response signals from the ECUs that have been memorized as those connected to the sub bus 11, the hybrid vehicle control ECU determines that a malfunction exists.
- If 2 or more DTCs are output during the DTC check, one side of the CAN branch wire may be open (one side of the CANH [CAN branch wire]/CANL [CAN branch wire] of the ECU and/or sensor is open).
