DESCRIPTION

  • *1: for Radio and Display Type

  • *2: for Navigation Receiver Type

  • The combination meter assembly communicates with the ECM via the CAN communication system.

  • The combination meter assembly communicates with the brake actuator assembly (skid control ECU) via the CAN communication system.

  • The combination meter assembly communicates with the power steering ECU assembly via the CAN communication system.

  • The combination meter assembly communicates with the main body ECU (multiplex network body ECU) via the CAN communication system.

  • The combination meter assembly communicates with the airbag sensor assembly via the CAN communication system.

  • The combination meter assembly communicates with the radio and display receiver assembly*1 or navigation receiver assembly*2 via the CAN communication system.

  • The combination meter assembly communicates with the Driving support ECU assembly via the CAN communication system.

DTC No.
