If any DTCs are simultaneously output for 2 or more slave units that are connected in series, there may be a problem between the master unit and the slave unit which is closest to the master unit. Therefore, first proceed with troubleshooting of that slave unit.
For example, if DTCs are output for the radio receiver assy and stereo component amplifier assy, there may be a problem between the master unit and radio receiver assy. ( (Scheme 246)and (Scheme 247) below.)
