CAUTION / NOTICE / HINT

Note


  • When using the GTS with the power switch off to troubleshoot:

    Connect the GTS to the vehicle, and turn a courtesy switch on and off at 1.5 seconds intervals until communication between the GTS and vehicle begins.

  • When the sliding roof drive gear sub-assembly is replaced or removed and reinstalled, it requires initialization Click here.*

  • When a power window regulator motor assembly is replaced or removed and reinstalled, it requires initialization Click here.

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


Tech Tips

When DTC B2325 and a LIN communication stop DTC are output simultaneously, first perform the troubleshooting for the LIN communication stop DTC. Then perform the troubleshooting for DTC B2325.
