Lexus NX: 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 wireless transmitter. Then, the main body ECU (multiplex network body ECU) activates the power window motor and sends the remote control signals to the sliding roof drive gear sub-assembly (sliding roof ECU) via LIN communication. The sliding roof drive gear sub-assembly (sliding roof ECU) 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 both functions are ON.
