Inspection Procedure

WARNING: This page is about a different car, the 2006 Toyota 4Runner. However, it is still accessible from the selected car via links, so may be relevant.

CHECK WIRE HARNESS (POWER SOURCE)
1. Disconnect the P9 switch connector.
2. Turn the ignition switch ON.
3. Check the voltage between terminal 4 of the wire harness side connector of the switch and the body ground.
  Standard: 10 - 14 V
NG: REPAIR OR REPLACE HARNESS AND CONNECTOR (SWITCH <==> RELAY)

OK: GO TO NEXT STEP

INSPECT POWER WINDOW REGULATOR SWITCH ASSY (PASSENGER SIDE)

Remove the power window switch.

Check the continuity between the terminals of the switch connector when the switch is operated.

Standard:

TERMINAL SPECIFIED CONDITION TABLE

Terminal No.	Switch	Specified Condition
1 <==> 2, 3 <==> 4	UP	Continuity
1 <==> 2, 3 <==> 5	OFF	Continuity
1 <==> 4, 3 <==> 5	DOWN	Continuity

Check the continuity between the P9 switch connector and the body ground.

Standard:

TERMINAL SPECIFIED CONDITION TABLE

Terminal No.	Specified Condition
P9-1 <==> Body ground	No continuity
P9-3 <==> Body ground	No continuity

NG: REPAIR OR REPLACE HARNESS AND CONNECTOR

OK: GO TO NEXT STEP

INSPECT POWER WINDOW REGULATOR MOTOR ASSY RH (PASSENGER SIDE)

Remove the motor (See OVERHAUL ).
Apply battery voltage to connector terminals 1 and 2.

Check that the motor rotates smoothly.

Fig 4: Checking That Motor Rotates Smoothly

Standard:

TERMINAL MOTOR GEAR ROTATION TABLE

Terminal No.	Motor Gear Rotation
Battery positive voltage --> 1 Battery negative voltage --> 2	Clockwise
Battery positive voltage --> 2 Battery negative voltage --> 1	Counterclockwise

NG: REPLACE POWER WINDOW REGULATOR MOTOR ASSY RH (PASSENGER SIDE)

OK: REPAIR OR REPLACE HARNESS AND CONNECTOR (MASTER SWITCH <==> SWITCH)
