SLIDING ROOF SYSTEM - Sliding Roof Control Switch Circuit |
DESCRIPTION
If either the sliding function or tilt function does not operate, there may be a malfunction in the sliding roof switch assembly circuit.
WIRING DIAGRAM
INSPECTION PROCEDURE
- NOTICE:
- When the sliding roof drive gear sub-assembly is reinstalled or replaced, the sliding roof drive gear sub-assembly must be initialized (COROLLA_ZRE142 RM000001VJR066X.html).
| 1.INSPECT MAP LIGHT ASSEMBLY (SLIDING ROOF SWITCH ASSEMBLY) |
Remove the map light assembly (COROLLA_ZRE142 RM000001I0602AX.html).
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection
| Switch Condition
| Specified Condition
|
O10-4 (OPN) - O10-7 (GND)
| SLIDE OPEN switch pushed
| Below 1 Ω
|
O10-4 (OPN) - O10-7 (GND)
| SLIDE OPEN switch not pushed
| 1 MΩ or higher
|
O10-2 (CLS) - O10-7 (GND)
| SLIDE CLOSE switch pushed
| Below 1 Ω
|
O10-2 (CLS) - O10-7 (GND)
| SLIDE CLOSE switch not pushed
| 1 MΩ or higher
|
O10-3 (UP) - O10-7 (GND)
| TILT UP switch pushed
| Below 1 Ω
|
O10-3 (UP) - O10-7 (GND)
| TILT UP switch not pushed
| 1 MΩ or higher
|
O10-4 (OPN) - O10-7 (GND)
| TILT DOWN switch not pushed
| 1 MΩ or higher
|
O10-2 (CLS) - O10-7 (GND)
| TILT DOWN switch not pushed
| 1 MΩ or higher
|
Measure the voltage using diode test mode.
- Standard Voltage:
Tester Connection
| Switch Condition
| Specified Condition
|
Positive lead → O10-2 (CLS)
Negative lead → O10-7 (GND)
| TILT DOWN switch pushed
| 0.4 to 1.2 V
|
Positive lead → O10-4 (OPN)
Negative lead → O10-7 (GND)
| TILT DOWN switch pushed
| 0.4 to 1.2 V
|
Positive lead → O10-7 (GND)
Negative lead → O10-2 (CLS)
| TILT DOWN switch pushed
| 2.5 to 3.3 V
|
Positive lead → O10-7 (GND)
Negative lead → O10-4 (OPN)
| TILT DOWN switch pushed
| 2.5 to 3.3 V
|
- NOTICE:
- This procedure is for using a digital tester which has diode test mode such as a TOYOTA electrical tester. If a tester which does not have diode test mode is used, the diode may break.
| 2.CHECK HARNESS AND CONNECTOR (MAP LIGHT ASSEMBLY - SLIDING ROOF DRIVE GEAR AND BODY GROUND) |
Disconnect the O11 ECU connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection
| Condition
| Specified Condition
|
O11-1 (OPN) - O10-4 (OPN)
| Always
| Below 1 Ω
|
O11-2 (CLS) - O10-2 (CLS)
| Always
| Below 1 Ω
|
O11-6 (UP) - O10-3 (UP)
| Always
| Below 1 Ω
|
O11-1 (OPN) - Body ground
| Always
| 10 kΩ or higher
|
O11-2 (CLS) - Body ground
| Always
| 10 kΩ or higher
|
O11-6 (UP) - Body ground
| Always
| 10 kΩ or higher
|
O10-7 (GND) - Body ground
| Always
| Below 1 Ω
|
| | REPAIR OR REPLACE HARNESS OR CONNECTOR |
