DIAGNOSIS SYSTEM
Revision: 2006 January2006 M35/M45
Connection Line Between Units Is Yellow (2 or More Lines)
When 2 or more connection lines between control unit (AV control unit, NAVI control) and each unit are dis-
played in yellow, these communication system lines may be open or shorted. The malfunctioning parts can be
detected by the combination of the connection lines displayed in yellow.
