3.CHECK HARNESS AND CONNECTOR (SLIDING ROOF DRIVE GEAR - MAP LIGHT) |
Disconnect the R5 drive gear connector.
Disconnect the R7 map light connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection | Condition | Specified Condition |
R5-10 (UP) - R7-19 (UP) | Always | Below 1 Ω |
R5-8 (DWN) - R7-18 (DOWN) | Always | Below 1 Ω |
R5-7 (OPN) - R7-8 (OPN) | Always | Below 1 Ω |
R5-9 (CLS) - R7-7 (CLS) | Always | Below 1 Ω |
R7-17 (GND9) - Body ground | Always | Below 1 Ω |
R5-2 (E) - Body ground | Always | Below 1 Ω |
R5-10 (UP) or R7-19 (UP) - Body ground | Always | 10 kΩ or higher |
R5-8 (DWN) or R7-18 (DOWN) - Body ground | Always | 10 kΩ or higher |
R5-7 (OPN) or R7-8 (OPN) - Body ground | Always | 10 kΩ or higher |
R5-9 (CLS) or R7-7 (CLS) - Body ground | Always | 10 kΩ or higher |
| REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
|
4.INSPECT MAP LIGHT ASSEMBLY (SLIDING ROOF SWITCH) |
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection | Switch Condition | Specified Condition |
19 (UP) - 17 (GND9) | UP switch is pressed | Below 1 Ω |
19 (UP) - 17 (GND9) | UP switch is not pressed | 10 kΩ or higher |
18 (DOWN) - 17 (GND9) | DOWN switch is pressed | Below 1 Ω |
18 (DOWN) - 17 (GND9) | DOWN switch is not pressed | 10 kΩ or higher |
8 (OPN) - 17 (GND9) | OPEN switch is pressed | Below 1 Ω |
8 (OPN) - 17 (GND9) | OPEN switch is not pressed | 10 kΩ or higher |
7 (CLS) - 17 (GND9) | CLOSE switch is pressed | Below 1 Ω |
7 (CLS) - 17 (GND9) | CLOSE switch is not pressed | 10 kΩ or higher |
| REPLACE MAP LIGHT ASSEMBLY (SLIDING ROOF SWITCH) ()
