Title: SLIDING ROOF / CONVERTIBLE: SLIDING ROOF SYSTEM (for HV Model): Remote Control System does not Operate; 2019 - 2022 MY Avalon HV [04/2018 -        ]

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 assembly) via LIN communication. The sliding roof ECU (sliding roof drive gear 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.
