System Description
Multi AV system means that the following systems are integrated.
- AV control unit functions by transmitting/receiving data one by one with each unit (slave unit) that configures them completely as a master unit by connecting between units that configure the MULTI AV system with two AV communication lines (H, L).
- Two AV communication lines (H, L) adopt a twisted pair line that is resistant to noise.
- AV control unit is connected by CAN communication, and it receives a data signals from the ECM, unified meter and A/C amp. It computes and displays fuel economy information values with the obtained information. The transmitting/receiving of data signals is performed by the BCM. In addition, it transmits the required signal of vehicle setting and receives the response signal.
- AV control unit is connected with display and serial communication, and it transmits the required signal from the display and the display control and receives the response signal from the front display. Also, it is connected with satellite radio by serial communication, and it transmits the operating signal and receives the display signal.
NOTE:
AV control unit can perform CONSULT-III self-operating function and on board self-diagnosis.
- CONSULT-III self-diagnosis: refer to AV-37, "CONSULT-III Function (MULTI AV)". CONSULT-III Function (Multi AV)
- On board self-diagnosis: refer to AV-28, "Diagnosis Description". Diagnosis Description
AUXILIARY INPUT SYSTEM
- Image and sound can be output from an external device by connecting a device with auxiliary input jacks.
- Operation can be performed by the multifunction switch and steering switch. Multifunction switch transmits operation signal to AV control unit with communication.
