Inspection Procedure

NOTE:

The power window control system uses a multiplex communication system (BEAN). Inspect the communication function by following How to Proceed with Troubleshooting. Refer to HOW TO PROCEED WITH TROUBLESHOOTING . Troubleshoot the power window control system after confirming that the communication system is functioning properly.
When the power window regulator motor assembly (for driver side) 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 re-initialized by repeating the following operations at least 5 times:
1. Close the power window by fully pulling up the multiplex network master switch assembly and holding it at the auto up position.
2. Open the power window by fully pushing down the multiplex network master switch assembly.
When the ECU determines that the power window regulator motor assembly (for driver side) has a malfunction, DTC B2311 is set.
