INSPECTION PROCEDURE

Note


  • When the sliding roof drive gear sub-assembly (sliding roof ECU) is reinstalled or replaced, the sliding roof drive gear sub-assembly must be initialized Click here.

  • Since the sliding roof system has functions that use BEAN communication, first confirm that there is no malfunction in the communication system by inspecting the BEAN communication functions in accordance with the How to Proceed with Troubleshooting procedure. Then, conduct the following inspection procedure.
