      3.CHECK CAN COMMUNICATION SYSTEM

      1. Check for output DTCs.

        HINT:
        The absorber control ECU is connected to the CAN communication system. Therefore before starting troubleshooting, make sure to check that there is no trouble in the CAN communication system.


      		.
      CAN COMMUNICATION SYSTEM DTC IS OUTPUT: PROCEED TO CAN COMMUNICATION SYSTEM

      		.
      NO CAN COMMUNICATION SYSTEM DTC IS OUTPUT: GO TO STEP 4

      4.CHECK MULTIPLEX COMMUNICATION SYSTEM

      1. Check for output DTCs.

        HINT:
        The absorber control ECU sends the signals from each indicator light to the gateway ECU via CAN communication, and the gateway ECU sends the signals to the combination meter assembly via the multiplex communication system (BEAN).


      		.
      MULTIPLEX COMMUNICATION SYSTEM DTC IS OUTPUT: PROCEED TO MULTIPLEX COMMUNICATION SYSTEM

      		.
      NO MULTIPLEX COMMUNICATION SYSTEM DTC IS OUTPUT: GO TO STEP 5

      5.CHECK DTCS
