FUNCTION DIAGNOSIS
MULTI AV SYSTEM
System DiagramINFOID:0000000001728627
System DescriptionINFOID:0000000001728628
Multi AV system means that the following systems are integrated.
 Two AV communication lines (H, L) connect between units that configure MULTI AV system. NAVI control
unit controls by sending/receiving data one by one with each unit (slave unit) that configures them com-
pletely as a master unit.
 Two AV communication lines (H, L) adopt a twisted pair line that is resistant to noise.
 NAVI control unit is connected by CAN communication, and it receives data signal from ECM, combination
meter. It computes and displays fuel economy information value with the obtained information. Sending/
receiving of data signal is performed by BCM. Also, it sends the required signal of vehicle setting and
receives the response signal.
