PANORAMIC MOON ROOF SYSTEM 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 ECU (sliding roof drive gear assembly) via LIN communication. The sliding roof ECU (sliding roof drive gear assembly) receives the signals and activates the sliding roof motor.

CAUTION / NOTICE / HINT

Note


  • The sliding roof key-linked function and sliding roof wireless transmitter-linked function are operative when the power window customize settings "Door Key P/W Up", "Door Key P/W Down", "P/W Up W/Transmit" and "P/W Down W/Transmit" are set to "ON" using the GTS. (The default setting of each is "OFF".) (w/o Canister Pump Module)

  • The sliding roof key-linked function is operative when the power window customize settings "Door Key P/W Up" and "Door Key P/W Down" are set to "ON" using the GTS. (The default setting of each is "OFF".) (w/ Canister Pump Module)

  • If the sliding roof ECU (sliding roof drive gear assembly) is removed and reinstalled or replaced, the sliding roof ECU (sliding roof drive gear assembly) must be initialized.

  • Before replacing the main body ECU (multiplex network body ECU), refer to Service Bulletin.

  • The vehicle battery supplies power to the main body ECU (multiplex network body ECU) via the door control battery. Therefore, before proceeding with troubleshooting, perform an on-vehicle inspection and confirm that the main body ECU (multiplex network body ECU) power source circuit is normal.*
