Power Windows: Other Toyota Sienna I

ADJUSTING METHOD FOR JAM PROTECTION

Note. Use this procedure when power window motor has been replaced or when power window motor has been run while removed from vehicle.

To adjust limit switch to OFF position, connect motor to harness connector and operate power window motor in UP direction for 4-5 seconds. This sets limit switch to full UP position (OFF).

Land Cruiser & RAV4

If window reverses when window is being raised in AUTO UP mode, check door glass run, window regulator, window motor or window guide for sign of damage or misalignment. Resistance in window glass movement causes window to reverse direction. Check power window motor limit switch for proper adjustment. See ADJUSTING METHOD FOR JAM PROTECTION under ADJUSTMENTS. If all mechanical checks are okay, replace driver's power window master switch with a known-good unit and retest. See POWER WINDOW SWITCH under REMOVAL & INSTALLATION.

AUTO REVERSE INOPERATIVE WITH OBSTRUCTION IN WINDOW

Note. This test diagnoses inoperative AUTO REVERSE operation (jam function) when foreign object restricts window up operation. AUTO REVERSE mode will not operate when window is within .157" (4 mm) of fully open position.

1. Ensure all power window modes function normally (i.e., UP, DOWN, AUTO UP, AUTO DOWN and key OFF). If all modes function normally, go to next step. If all modes do not function normally, perform appropriate test.
2. AUTO REVERSE should operate when there is resistance to power window motor while raising window. If window opening is greater than 7.874" (200 mm) when window glass travel is obstructed, window will automatically lower 1.969" (50 mm) and stop. If window opening is 7.874" (200 mm) or less when window glass travel is obstructed, window will automatically lower until opening is 7.874" (200 mm) and stop. If operation is as specified, system is okay at this time. If operation is not as specified, go to next step.
3. Check power window motor limit switches for proper adjustment. See «ADJUSTING METHOD FOR JAM PROTECTION»(ref-9144-S38288401962000100600000) under ADJUSTMENTS. Ensure power window motor is installed correctly. If motor is installed correctly and AUTO REVERSE still does not operate as specified, replace power window master switch or power window control switch. See «POWER WINDOW SWITCH»(ref-9144-S14947635282000100600000) under REMOVAL & INSTALLATION.

ONE-TOUCH POWER WINDOW IS INOPERATIVE

Note. When a fault for one-touch mode in driver's power window master switch occurs, AUTO light on power window master switch will output a flash code. After 30 seconds, AUTO light will stop flashing and will stay on. If ignition switch is turned to OFF position during flash mode, flashing will stop.

Scheme 14

1. Turn ignition switch to ON position and toggle power window master switch to UP or DOWN position for driver's side window only. Ensure power window master switch AUTO light begins to flash fault code. (Scheme 14) For fault Code 1, go to next step. For fault Code 2 or 3, go to step 3. If AUTO light does not stay illuminated after 30 seconds, or flashes stop after ignition switch is turned to OFF position, replace power window master switch. See «POWER WINDOW SWITCH»(ref-9144-S14947635282000100600000) under REMOVAL & INSTALLATION.
2. Fault Code 1 occurs when there is an error in power window motor limit switch. Remove power window master switch from door panel, with harness connector attached. See «POWER WINDOW SWITCH»(ref-9144-S14947635282000100600000) under REMOVAL & INSTALLATION. Measure voltage by backprobing between terminals No. 1 and 5 at power window master switch harness connector. Voltage should change from zero volts when window is fully closed, to battery voltage while window is opening. If voltage is not as specified, go to next step. If voltage is as specified, replace power window master switch. If AUTO UP and AUTO DOWN does not work after power window master switch is replaced, replace power window motor.
3. Disconnect power window master switch and driver's power window motor from harness connectors. Check continuity between power window master switch terminals and driver's power window motor terminals. See «ONE-TOUCH POWER WINDOW TESTS»(ref-9144-S39860578572000100600000) table. If continuity is present at all measurements, go to next step. If continuity is not present at any measurement, repair open circuit in affected wire. ONE-TOUCH POWER WINDOW TESTS Application Check Between Master Switch Terminal No. & Driver's Window Motor Terminal No. Land Cruiser (1) 1 & 4 (2) 7 & 3 (2) 5 & 5 RAV4 (2-Door) (1) 4 & 4 (1) 1 & 3 (1) 10 & 5 RAV4 (4-Door) (1) 1 & 1 (2) 7 & 3 (2) 5 & 5 (1) (Scheme 15)and (Scheme 19). (2) see scheme 3and (Scheme 19).
4. With master switch and driver's window motor disconnected, check for continuity between terminals No. 1, 5 and 7 at 14-pin master switch harness connector on Land Cruiser and RAV4 4-door, or terminals No. 1, 4 and 10 on RAV4 2-door. (Scheme 15) See «WIRING DIAGRAMS»(ref-9144-S22975164872000100600000). If continuity is not present, go to next step. If continuity is present, repair short between affected wires.
5. With master switch and driver's window motor disconnected, check continuity between ground and terminals No. 3, 4, 5 at driver's power window motor harness connector. If continuity is not present, go to next step. If continuity is present, repair short to ground in affected wire.
6. Connect harness connectors to master switch and driver's power window motor. Ensure AUTO UP and AUTO DOWN function operates correctly. If AUTO UP and AUTO DOWN function still does not operate correctly, replace power window motor.
