When a setting assignment using the multi-display is performed, the smart entry and start system (for Start Function), digital key system*1, audio and visual system*2*3 and navigation system*2*4 will use the device when performing a search. If detected, settings can be assigned. If there is no detection, it is suspected that the radio and display receiver assembly or each system is malfunctioning.
*1: for vehicles which display the assigned settings of Digital key system on the multi-display
*2: for vehicles which display the assigned settings of Bluetooth devices on the multi-display
*3: w/ Audio and Visual System
*4: w/ Navigation System
Before replacing the main body ECU (multiplex network body ECU), refer to Service Bulletin.
Check the problem symptoms.
