Remote Control System Does Not Operate

SLIDING ROOF / CONVERTIBLE: SLIDING ROOF SYSTEM: Remote Control System does not Operate
- 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*1. 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.

* *1: w/ Daytime Running Light Control

INSPECTION PROCEDURE

NOTICE:
* The sliding roof key-linked function and sliding roof wireless transmitter-linked function*1 can be customized. Make sure that both functions are ON Customize Parameters.
*1: w/ Daytime Running Light Control
* When the sliding roof ECU (sliding roof drive gear sub-assembly) is removed and reinstalled or replaced, the sliding roof ECU (sliding roof drive gear sub-assembly) must be initialized Initialization.
* Since the sliding roof system has functions that use LIN communication, first confirm that there is no malfunction in the LIN communication system with the How to Proceed with Troubleshooting procedure How To Proceed With Troubleshooting.
* When sliding roof ECU (sliding roof drive gear sub-assembly) DTC is output, first perform troubleshooting for the sliding roof ECU (sliding roof drive gear sub-assembly) DTC.
