1999-2000 ACCESSORIES & EQUIPMENT
Power Door Locks - Trucks
DESCRIPTION & OPERATION
Power door locks are all controlled through a multipurpose Electronic Control Unit (ECU) or integration relay.
The Land Cruiser is controlled through the instrument cluster ECU. The 4Runner is controlled through the body
ECU, and the Sienna, Tundra, RAV4 and Tacoma are all controlled through the integration relay. Each system
also consists of a door lock motor at each door, tailgate, liftgate and sliding door, a master door lock switch at
driver's door, which controls all other doors, tailgate, liftgate and sliding doors and a switch at each door,
tailgate, liftgate and sliding doors.
To operate door locks from the outside, insert door key into door lock cylinder and turn it to the right
(clockwise) once will unlock the driver's door and turning it a second time will unlock all other doors, tailgate,
liftgate and sliding doors. Passenger door will unlock all other doors when it is unlocked. When either front
door lock is turned to left (counter clockwise) all other doors will lock. The driver's door has a master lock
switch which will lock all doors on the vehicle. Each door and sliding doors have a switch inside that controls
each door lock.

1999-2000 ACCESSORIES & EQUIPMENT
Power Windows - Trucks
DESCRIPTION & OPERATION
Depending on model, system components vary. System components may consist of a power main relay, body
control ECU, integration relay or instrument ECU. See WIRING DIAGRAMS
. All models have power
window switches and power window motors for each door. With ignition switch in ON position, battery voltage
is supplied through power main relay or body control ECU to power window switches. Power window switch
supplies power and ground for power window motors. 4Runner also has a power window switch and lock
switch for tailgate door.
Driver's power window switch offers one-touch operation of driver's window. Driver's power window switch
also includes a lock-out feature to prevent passengers from operating any other power window switches.
ADJUSTMENTS
ADJUSTING METHOD FOR JAM PROTECTION
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).
TROUBLE SHOOTING
WINDOW REVERSES WHEN OPERATED IN AUTO UP MODE (DRIVER'S WINDOW ONLY)
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.
AUTO REVERSE INOPERATIVE WITH OBSTRUCTION IN WINDOW NOTE: Use this procedure when power window motor has been replaced or when
power window motor has been run while removed from vehicle.
NOTE: Trouble shooting available for Land Cruiser and RAV4 models only. For
connector views for trouble shooting diagnostic steps, see CONNECTOR
VIEWS .
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. Remove master switch and disconnect 14-pin connector. Connect jumper wire between 12-volt battery
positive terminal and master switch terminals No. 3 and 10. Connect another jumper between battery
negative terminal and master switch terminal No. 4.
2. Measure voltage by backprobing between specified terminals with driver's power window switch in
specified position. See POWER WINDOW MASTER SWITCH VOLTAGE TEST (4RUNNER)

table. Voltage should be 10-14 volts. If voltage is not as specified, replace power window switch. If
voltage is as specified, switch is okay.

4Runner
Using an ohmmeter, check continuity between specified terminals with back door/tailgate power window switch
in specified position. See POWER WINDOW SWITCH CONTINUITY TEST (4RUNNER
- BACK
DOOR/TAILGATE) table. See Fig. 13 . If continuity does not exist at specified terminals, replace appropriate
power window switch.
