                  DESCRIPTION
                  The combination meter assembly receives signals from this circuit to adjust the illumination of the combination meter assembly. The combination meter assembly sets the illumination level based on the user operation of the light control rheostat.

                        - 
When replacing the combination meter assembly, always replace it with a new one. If a combination meter assembly which was installed to another vehicle is used, the information stored in it will not match the information from the vehicle and a DTC may be stored.
 
                        - 
Before replacing the main body ECU (multiplex network body ECU), refer to smart key system (for Start Function).
