Lexus ES: 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.
