Electronic vehicle systems have made vehicles more comfortable and convenient to drive. They’ve also increased vehicle safety immeasurably. In your shop, however, they make complex repairs even more complex.
Every vehicle has different initialization and reset procedures for a growing list of systems. Searching for instructions takes time – and money! OE information is a must in order to maintain estimating and repair efficiency.
Here’s the manufacturer’s procedure to initialize the driver’s window and moon roof on a 2009 Toyota 4Runner.
This Technical Service Bulletin outlines the initialization procedure for the driver’s door power window and the moon roof on 2009 4Runners.
If the battery has been disconnected, the ECU won’t be able to detect and memorize the driver’s door power window and moon roof positions, resulting in the following features being inoperative:
• One-touch open and close of driver’s door power window with jam protection.
• One-touch slide open and close of moon roof with jam protection.
• One-touch tilt up and down of moon roof with jam protection.
Use the following initialization procedure whenever the battery has been disconnected.
Always refer to ALLDATA Collision for safety procedures, identification of material types, recommended refinish materials and removal and installation procedures. Always refer to the vehicle manufacturer for questions relating to applicable or non-applicable warranty repair information.
NOTE: Any time the battery terminal has been disconnected, the driver’s door power window and moon roof must be re-initialized.
1. Turn the ignition switch to the “IG-ON” position. NOTE: When not initialized, the power switch for the driver’s door power window will blink (Figure 1).
2. Push the driver’s power window switch “down” to open the window.
3. Pull “up” the driver’s door power window switch until the window closes, and continue holding it for approximately one second until the switch stops blinking and remains illuminated (Figure 2).
4. Check for proper operation of the “one-touch open/close” by pushing the switch briefly to the “down” and “up” positions.
NOTE: The jam protection function is enabled by completing the initialization procedure.
1. Turn the ignition to the “IG-ON” position.
2. Push and hold the “tilt up” side of the switch until the moon roof tilts all the way up and then tilts down slightly, about 10 mm (0.39 inch) at the rear (Figure 3).
3. Check for proper operation of the “one-touch slide open/close” and “one-touch tilt up/down” functions by pushing the switch briefly to the “slide open” and “tilt up” positions.
If the power window is unable to close after initialization, perform the following procedure.
NOTE: If the power window switch is continuously operated for a long time, the power window motor will stop to prevent additional load on the motor. Continuing to press the power window switch even after the motor has stopped will cause the switch to blink and will restrict the auto up/down function and remote up/down function. If this happens, wait for a few minutes before attempting to reset the motor again.
1. Disconnect the negative (-) battery terminal. After 10 seconds, reconnect the battery terminal.
2. Turn the ignition switch to the “on” position. Close the door glass halfway by pressing the switch. Then, fully pull up on the switch until the door glass is fully closed, and continue holding the switch for approximately one second after the door glass is fully closed.
3. Check for proper operation of the auto up/down function.
4. If the power window motor is still unable to close, turn the ignition switch to the “on” position. Close the door glass halfway by pressing the switch. Then fully pull up on the switch until the door glass is fully closed, and continue holding the switch for approximately 12 seconds after the door glass is fully closed.
5. Check for proper operation of the auto up/down function.
