RM38T0EC _59 Vehicle Exterior _114986 SLIDING ROOF / CONVERTIBLE _0583911 SLIDING ROOF SYSTEM(Production Date from 2023/04) J

SLIDING ROOF / CONVERTIBLE  SLIDING ROOF SYSTEM(Production Date from 2023/04)  Remote Control System does not Operate  


DESCRIPTION

The main body ECU (multiplex network body ECU) receives remote control signals from the driver door key cylinder or electrical key transmitter sub-assembly. Then, the main body ECU (multiplex network body ECU) activates the power window motor and sends the remote control signals to the sliding roof ECU (sliding roof drive gear sub-assembly) via LIN communication. The sliding roof ECU (sliding roof drive gear sub-assembly) receives those signals and activates the sliding roof motor.

CAUTION / NOTICE / HINT

NOTICE:
·

The sliding roof key-linked function and sliding roof wireless transmitter-linked function can be customized. Make sure that the customize settings of both functions are set to ON.
