WIRING DIAGRAM
INSPECTION PROCEDURE
| 1.INITIALIZE SLIDING ROOF DRIVE GEAR SUB-ASSEMBLY (SLIDING ROOF ECU) |
Check that the sliding roof drive gear can be initialized ().
- OK:
- Sliding roof drive gear can be initialized.
Check the DTCs ().
Result| Result | Proceed to |
| No DTC is output | A |
| DTC B2343 is output | B |
| | REPLACE SLIDING ROOF DRIVE GEAR SUB-ASSEMBLY (SLIDING ROOF ECU) ()
|
|
|
| 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) ()
|
|
|
| OK | |
| |
| REPLACE SLIDING ROOF DRIVE GEAR SUB-ASSEMBLY (SLIDING ROOF ECU) ()
