for RHD| Tester Connection | Condition | Specified Condition |
| I26-12 (U) - I30-5 (SU) | Always | Below 1 Ω |
| I26-13 (D) - I30-2 (SD) | Always | Below 1 Ω |
| I26-12 (U) or I30-5 (SU) - Body ground | Always | 10 kΩ or higher |
| I26-13 (D) or I30-2 (SD) - Body ground | Always | 10 kΩ or higher |
| | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
|

| I31-12 (U) - J23-5 (SU) | Always | Below 1 Ω |
| I31-13 (D) - J23-2 (SD) | Always | Below 1 Ω |
| I31-12 (U) or J23-5 (SU) - Body ground | Always | 10 kΩ or higher |
| I31-13 (D) or J23-2 (SD) - Body ground | Always | 10 kΩ or higher |
for RHD| Tester Connection | Condition | Specified Condition |
| I26-18 (U) - J23-5 (SU) | Always | Below 1 Ω |
| I26-10 (D) - J23-2 (SD) | Always | Below 1 Ω |
| I26-18 (U) or J23-5 (SU) - Body ground | Always | 10 kΩ or higher |
| I26-10 (D) or J23-2 (SD) - Body ground | Always | 10 kΩ or higher |
| | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
|
| 5.CHECK HARNESS AND CONNECTOR (MULTIPLEX NETWORK MASTER SWITCH - REAR POWER WINDOW REGULATOR SWITCH RH) |
Disconnect the I31*1 or I26*2 multiplex network master switch assembly connector.
Disconnect the J21 rear power window regulator switch assembly RH connector.
Measure the resistance according to the value(s) in the table below.
