Scheme 2

1. CHECK WINDOW LOCK SWITCH HINT: Before performing the window lock switch operation check, make sure that the window lock switch is off (the switch is not pushed in). Check that the front passenger and rear windows* cannot be operated when the window lock switch of the power window regulator master switch assembly is pushed in. OK Front passenger and rear windows* are disabled. *: w/ Rear Power Window Check that the front passenger and rear windows* can be operated when the window lock switch of the power window regulator master switch assembly is pushed in again. OK Front passenger and rear windows* operate normally. *: w/ Rear Power Window
2. CHECK MANUAL UP / DOWN FUNCTION Check that the driver door power window operates as follows: OK Condition Master Switch Switch Operation Power Window Ignition switch ON (IG) Driver door Pulled halfway up UP (Closes) Pushed halfway down DOWN (Opens) Check that the front passenger door window and rear power windows operate as follows: OK Condition Regulator Switch Switch Operation Power Window Ignition switch ON (IG) Window lock switch off Front passenger door Pulled up UP (Closes) Pushed down DOWN (Opens) Rear LH door* Pulled up UP (Closes) Pushed down DOWN (Opens) Rear RH door* Pulled up UP (Closes) Pushed down DOWN (Opens) *: w/ Rear Power Window
3. CHECK AUTO UP / DOWN FUNCTION Check that the driver door power window operates as follows: OK Condition Master Switch Switch Operation Power Window Ignition switch ON (IG) Driver door Pulled up (One touch operation) AUTO UP (Closes) Pushed down (One touch operation) AUTO DOWN (Opens)
4. CHECK REMOTE MANUAL UP / DOWN FUNCTION Check that the front passenger door window and rear power windows operate as follows: OK Condition Master Switch Switch Operation Power Window Ignition switch ON (IG) Window lock switch off Front passenger door Pulled up UP (Closes) Pushed down DOWN (Opens) Rear LH door* Pulled up UP (Closes) Pushed down DOWN (Opens) Rear RH door* Pulled up UP (Closes) Pushed down DOWN (Opens) *: w/ Rear Power Window
5. CHECK POWER WINDOW OPERATION FUNCTION AFTER IGNITION SWITCH IS TURNED OFF Check that all the power windows can be operated with the power widow regulator master switch assembly and power window regulator switch assemblies (for front passenger door, rear LH and RH doors*) after the ignition switch is turned off. HINT: If the window lock switch is on, the power windows cannot be operated besides the driver door power window. Therefore, turn the window lock switch off before checking the window operation. *: w/ Rear Power Window Check that the key-off operation function does not operate after the driver door or front passenger door is opened immediately. HINT: If the driver door or front passenger door is opened during automatic window operation while the key-off operation function is on, the window will stop operating. Check that all the power windows cannot be operated after more than approximately 43 seconds have elapsed since the ignition switch was turned off.
6. CHECK JAM PROTECTION FUNCTION Check the basic function. WARNING: Do not put your fingers between the door frame and door glass to check the jam protection function. Also, prevent any part of your body from being caught during inspection. HINT: The jam protection function operates during both the auto up and manual up operations while the hybrid control system is started or the ignition switch is ON (IG), and also 43 seconds have elapsed after the ignition switch was turned off. Fully open the driver door window. Set a check jig wrapped with a piece of cloth near the window fully closed position. TEXT IN ILLUSTRATION *a Check Jig *b Cloth Operate the auto up or manual up function to check that the power window stops and goes down after the check jig is caught between the window and door frame, and stops when the opening reaches approximately 200 mm (7.87 in.) or until approximately 5 seconds elapse. HINT: If the check jig is caught when the opening is approximately 75 mm (2.95 in.) or more, the power window goes down for approximately 125 mm (4.93 in.) or until approximately 2.5 seconds elapse. While the power window is moving down, check that the door glass cannot be raised when the power window switch is used.
7. CHECK POWER WINDOW REGULATOR MASTER SWITCH LED ILLUMINATION Check the LED illumination (power window regulator master switch assembly). Check that the LED located on the power window regulator master switch assembly illuminates when the ignition switch is turned to ON (IG).

DATA LIST / ACTIVE TEST [12/2013 - ]

1. DATA LIST HINT: Using the Techstream to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time. NOTE: In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not. Connect the Techstream to the DLC3. Turn the ignition switch to ON (IG). Turn the Techstream on. Enter the following menus: Body Electrical / D-Door Motor or Main Body / Data List. Read the Data List according to the display on the Techstream.

2. ACTIVE TEST HINT: Using the Techstream to perform Active Tests allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests. Connect the Techstream to the DLC3. Turn the ignition switch to ON (IG). Turn the Techstream on. Enter the following menus: Body Electrical / D-Door Motor or Main Body / Active Test. Perform the Active Test according to the display on the Techstream. WARNING: Be careful to avoid injuries as this test causes vehicle parts to move. During the Active Test, the jam protection function will not operate.
