3. Check the voltage between the terminal 4 of the wire harness side connector and the body ground.

   Standard voltage

   Terminal No.	Condition	Specified Condition
   P39-4 (B) - Body ground	Ignition switch ON	10 to 14 V

NG → REPAIR OR REPLACE HARNESS AND CONNECTOR (REGULATOR SWITCH - RELAY) 

OK: Go to next step 

1. Remove the regulator switch.

2. Check the resistance between the switch terminals when the switch is operated, as shown in the table below.

   Standard resistance

   Terminal No.	Regulator Switch	Specified Condition
   1 - 2, 3 - 4	UP	Below 1 Ω
   1 - 2, 3 - 5	OFF
   1 - 4, 3 - 5	DOWN

NG → REPLACE POWER WINDOW REGULATOR SWITCH (REAR RH) 

OK: Go to next step 

1. Disconnect the P43 motor connector.

2. Check the resistance between the wire harness side connectors.

   Standard resistance

   Terminal No.	Specified Condition
   P39-1 (D) - P43-2	Below 1 Ω
   P39-3 (U) - P43-1

3. Check the resistance between the P39 regulator switch connector and body ground.

   Standard resistance

   Terminal No.	Specified Condition
   P39-1 (D) - Body ground	10 kΩ or higher
   P39-3 (U) - Body ground

NG → REPAIR OR REPLACE HARNESS AND CONNECTOR 

OK: Go to next step 

1. Remove the motor.

2. Apply battery voltage to connector terminals 1 and 2.
3. Check that the motor smoothly rotates.
   NOTE:

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

   Standard

   Terminal No.	Specified Condition
   Battery positive (+) → 1 Battery negative (-) → 2	Motor gear rotates counterclockwise
   Battery positive (+) → 2 Battery negative (-) → 1	Motor gear rotates clockwise

NG → REPLACE POWER WINDOW REGULATOR MOTOR ASSEMBLY (REAR RH) 

OK → REPAIR OR REPLACE HARNESS AND CONNECTOR (MASTER SWITCH - REGULATOR SWITCH)
