DESCRIPTION
When the engine is running or the engine switch is on (IG), the power window regulator motor assembly (for driver side) is operated by the multiplex network master switch assembly. The power window regulator motor assembly (for driver side) has motor, regulator, and ECU functions.
Tech Tips
If the pulse sensor built into the power window regulator motor assembly (for driver side) malfunctions, the power window control system enters fail-safe mode. The remote up/down and auto up/down functions cannot be operated during fail-safe mode. However, the power window can be closed by holding the multiplex network master switch assembly in the auto up position, and opened manually by pushing down the multiplex network master switch assembly.

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 Click here. 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 reinitialized by repeating the following operations at least 5 times:
Close the power window by fully pulling up the multiplex network master switch assembly and holding it at the auto up position.
Open the power window by fully pushing down the multiplex network master switch assembly.
