INSPECTION PROCEDURE

Note


  • Inspect the fuses for circuits related to this system before performing the following inspection procedure.

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

  • Since the sliding roof system uses the LIN communication system, first confirm that there is no malfunction in the LIN communication system. Refer to the How to Proceed with Troubleshooting procedure Click here.
