WIRING DIAGRAM
INSPECTION PROCEDURE
| 1.INSPECT POWER WINDOW REGULATOR MOTOR |
Remove the power window motor.
Apply battery voltage to the motor connector according to the table below.
- Do not apply battery voltage 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 |
| | REPLACE POWER WINDOW REGULATOR MOTOR |
|
|
| 2.CHECK WIRE HARNESS (WINDOW REGULATOR MOTOR - MULTIPLEX NETWORK SWITCH) |
Disconnect the M16 (L13) and M3 (L4) connectors.
Measure the resistance according to the value(s) in the table below.
- Resistance:
- LHD models:
| Tester Connection | Condition | Specified Condition |
| M16-1 (DN) - M3-1 (D) | Always | Below 1 Ω |
| M16-6 (UP) - M3-2 (U) | Always | Below 1 Ω |
| M16-1 (DN) - Body ground | Always | 10 kΩ or higher |
| M16-6 (UP) - Body ground | Always | 10 kΩ or higher |
- RHD models:
| Tester Connection | Condition | Specified Condition |
| L13-1 (DN) - L4-1 (D) | Always | Below 1 Ω |
| L13-6 (UP) - L4-2 (U) | Always | Below 1 Ω |
| L13-1 (DN) - Body ground | Always | 10 kΩ or higher |
| L13-6 (UP) - Body ground | Always | 10 kΩ or higher |
| | REPAIR OR REPLACE HARNESS OR CONNECTOR |
