WIRING DIAGRAM
INSPECTION PROCEDURE
| 1.INSPECT REAR POWER WINDOW REGULATOR SWITCH ASSEMBLY LH |
Remove the rear power window regulator switch assembly LH ().
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
| Tester Connection | Switch Condition | Specified Condition |
| 4 (U) - 3 (B) | UP | Below 1 Ω |
| 2 (SD) - 1 (D) |
| 5 (SU) - 4 (U) | OFF | Below 1 Ω |
| 2 (SD) - 1 (D) |
| 5 (SU) - 4 (U) | DOWN | Below 1 Ω |
| 3 (B) - 1 (D) |
| | REPLACE REAR POWER WINDOW REGULATOR SWITCH ASSEMBLY LH ()
|
|
|
| 2.INSPECT REAR POWER WINDOW REGULATOR MOTOR ASSEMBLY LH |
Remove the rear window regulator motor assembly LH ().
Apply battery voltage to the motor connector according to the table below.
Text in Illustration| *1 | Motor Gear |
| *a | Counterclockwise |
| *b | Clockwise |
- OK:
| Measurement Condition | Specified Condition |
Battery positive (+) → 1
Battery negative (-) → 2 | Motor gear rotates clockwise |
Battery positive (+) → 2
Battery negative (-) → 1 | Motor gear rotates counterclockwise |
| | REPLACE REAR POWER WINDOW REGULATOR MOTOR ASSEMBLY LH ()
|
|
|
| 3.CHECK HARNESS AND CONNECTOR (REAR POWER WINDOW REGULATOR SWITCH LH - BATTERY) |
Disconnect the J23 rear power window regulator switch assembly LH connector.
Measure the voltage according to the value(s) in the table below.
- Standard Voltage:
| Tester Connection | Switch Condition | Specified Condition |
| J23-3 (B) - Body ground | Ignition switch ON | 11 to 14 V |

(to Rear Power Window Regulator Switch Assembly LH) |
| | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
|
| 4.CHECK HARNESS AND CONNECTOR (REAR POWER WINDOW REGULATOR SWITCH LH - REAR POWER WINDOW REGULATOR MOTOR LH) |
Disconnect the J23 rear power window regulator switch assembly LH connector.
Disconnect the J22 rear power window regulator motor assembly LH connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
| Tester Connection | Condition | Specified Condition |
| J23-4 (U) - J22-1 | Always | Below 1 Ω |
| J23-1 (D) - J22-2 | Always | Below 1 Ω |
| J23-4 (U) or J22-1 - Body ground | Always | 10 KΩ or higher |
| J23-1 (D) or J22-2 - Body ground | Always | 10 KΩ or higher |
| | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
|
| 5.CHECK HARNESS AND CONNECTOR (REAR POWER WINDOW REGULATOR SWITCH LH - MULTIPLEX NETWORK MASTER SWITCH) |
Disconnect the J23 rear power window regulator switch assembly LH connector.
Disconnect the I31*1 or I26*2 multiplex network master switch assembly connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
for LHD| Tester Connection | Condition | Specified Condition |
| J23-5 (SU) - I31-12 (U) | Always | Below 1 Ω |
| J23-2 (SD) - I31-13 (D) | Always | Below 1 Ω |
| J23-5 (SU) or I30-12 (U) - Body ground | Always | 10 kΩ or higher |
| J23-2 (SD) or I30-13 (D) - Body ground | Always | 10 kΩ or higher |
for RHD| Tester Connection | Condition | Specified Condition |
| J23-5 (SU) - I26-18 (U) | Always | Below 1 Ω |
