Rear Sunshade Shift-linked Function does not Operate when Shift Lever is Moved to R Position
SYSTEM DESCRIPTION
When the engine switch is on (IG) and the rear sunshade is raised, moving the shift lever to R causes the PNP switch to send a reverse-linked signal to
the ECM. Then the ECM sends the signal through the multiplex communication line to the multiplex network rear ECU, which sends the signal to the
rear sunshade relay. The relay then lowers the rear sunshade.
