WIRING DIAGRAM

INSPECTION PROCEDURE

1. INSPECT POWER WINDOW REGULATOR MOTOR

1. Remove the power window motor.

2. Apply battery voltage to the motor connector according to the table below.

   NOTICE:

   Do not apply battery to any terminals except terminals 1 and 2.

   Standard:

   Measurement Condition	Specified Condition
   Battery positive (+) → Terminal 1 (D) Battery negative (-) → Terminal 2 (U)	Motor gear rotates clockwise
   Battery positive (+) → Terminal 2 (U) Battery negative (-) → Terminal 1 (D)	Motor gear rotates counterclockwise

NG	REPLACE POWER WINDOW REGULATOR MOTOR

OK

2. CHECK WIRE HARNESS (WINDOW REGULATOR MOTOR - MULTIPLEX NETWORK MASTER SWITCH)

1. Disconnect the P19 and P20 (P21) connectors.

2. Measure the resistance according to the value(s) in the table below.

   Standard resistance:

   RHD Models:

   Tester Connection	Condition	Specified Condition
   P19-1 (UP) - P21-2 (U)	Always	Below 1 Ω
   P19-11 (DN) - P21-1 (D)	Always	Below 1 Ω
   P19-1 (UP) - Body ground	Always	10 kΩ or higher
   P19-11 (DN) - Body ground	Always	10 kΩ or higher

   Standard resistance:

   LHD Models:

   Tester Connection	Condition	Specified Condition
   P19-1 (UP) - P20-2 (U)	Always	Below 1 Ω
   P19-11 (DN) - P20-1 (D)	Always	Below 1 Ω
   P19-1 (UP) - Body ground	Always	10 kΩ or higher
   P19-11 (DN) - Body ground	Always	10 kΩ or higher

NG	REPAIR OR REPLACE HARNESS OR CONNECTOR

OK
