SYMPTOM TROUBLESHOOTING CHART
Scheme 3
- Always perform basic power window system inspection before troubleshooting.
- Troubleshooting procedures provide information unique to malfunctions of the automatic window return function.
| CAUTION | If any of the following conditions continues indefinitely, the power window motor will heat up causing the protection circuit (integrated in power window motor) to operate. If this occurs, the operation of the power window motor protection circuit temporarily disables the power windows. Continuous up and down operation of the power window. Continuously pulling up the power window switch while the window glass is fully closed. Continuously pressing the power window switch while the window glass fully opened. A malfunction in the power window system will be determined and the system will shift to malfunction mode if the power windows are operated up or down using the power window switch while the power window protection circuit is operating. While the power window system is in malfunction mode, but they do not operate using the auto open/close function. The power window system reverts to normal operation after performing the Power Window Initialization Procedure. |
Note. Initial setting must be performed for the switch of each seat. If the following operations have been performed, initial setting is reset, and auto up/down and two-step down operation are disabled. Therefore, performing initial setting is necessary. Negative battery cable disconnected or power window system power supply fuse removed, (perform initial setting for each door glasses.) Power window switch connector disconnected, (perform initial setting for the switch connected with the connector)
