SLIDING 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 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

Note


  • The sliding roof key-linked function and sliding roof wireless transmitter-linked function can be customized. Make sure that both functions are ON.

  • If the sliding roof drive gear sub-assembly (sliding roof ECU) is replaced, the sliding roof drive gear sub-assembly (sliding roof ECU) must be initialized.

    Click here

  • The sliding 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 the main body ECU (multiplex network body ECU) is replaced, refer to the Service Bulletin.

  • As the door control battery is installed between the vehicle battery and main body ECU (multiplex network body ECU), first perform the inspections in On-Vehicle Inspection to confirm that there are no malfunctions in the power source circuit for the main body ECU (multiplex network body ECU) before performing this troubleshooting procedure.*
