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.
*: w/o Canister Pump Module
CAUTION / NOTICE / HINT
Note
The panoramic moon roof key-linked function and panoramic moon 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 Down 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 panoramic moon 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) or roof sunshade ECU (sliding roof drive gear assembly) is removed and reinstalled or replaced, the sliding roof ECU (sliding roof drive gear assembly) must be initialized.
The panoramic moon roof system uses the CAN and LIN communication systems. First, confirm that there are no malfunctions in the CAN and LIN communication systems. Refer to How to Proceed with Troubleshooting.
If a sliding roof ECU (sliding roof drive gear assembly) or roof sunshade ECU (sliding roof drive gear assembly) DTC is output, perform troubleshooting for the DTC first.
Before replacing the main body ECU (multiplex network body ECU), refer to Service Bulletin.*
*: w/ Smart Entry and Start System
The vehicle battery supplies power to the main body ECU (multiplex network body ECU) via the door control battery. Therefore, before performing this troubleshooting procedure, make sure to perform an on-vehicle inspection to confirm that the main body ECU (multiplex network body ECU) power source circuit is normal.*
