Inspection Procedure

NOTE:
  • The power window control system uses a multiplex communication system (LIN communication system). Inspect the communication function by following How to Proceed with Troubleshooting. Refer to HOW TO PROCEED WITH TROUBLESHOOTING [08/2013 - ] . Troubleshoot the power window control system after confirming that the communication system is functioning properly.
  • When the front power window regulator motor assembly RH is reinstalled or replaced, the power window control system must be initialized.
  • After a door glass or a door glass run has been replaced, the jam protection function may operate unexpectedly when the auto up function is used. In such cases, the auto up function can be reinitialized by repeating the following operations at least 5 times:
    1. Close the power window by fully pulling up the front power window regulator switch assembly RH and holding it at the auto up position.
    2. Open the power window by fully pushing down the front power window regulator switch assembly RH.
  • When the ECU determines that the front power window regulator motor assembly RH has a malfunction, DTC B2311 is set.
