Note
Depending on the parts that are replaced during vehicle inspection or maintenance, performing initialization, registration or calibration may be needed. Refer to Precaution for Audio and Visual System.
When replacing the radio and display receiver assembly, always replace it with a new one. If a radio and display receiver assembly which was installed to another vehicle is used, the following may occur:
A communication malfunction DTC may be stored.
The radio and display receiver assembly may not operate normally.
The vehicle battery supplies power to the main body ECU (multiplex network body ECU) via the door control battery. Therefore, before performing troubleshooting, make sure to perform an on-vehicle inspection to confirm that the main body ECU (multiplex network body ECU) power source circuit is normal.*
