Inspection Procedure

WARNING: This page is about a different car, the 2009 Toyota Corolla. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: When the sliding roof drive gear sub-assembly is reinstalled or replaced, the sliding roof drive gear sub-assembly must be initialized (See INITIALIZATION ).

INSPECT MAP LIGHT ASSEMBLY (SLIDING ROOF SWITCH ASSEMBLY)

Remove the map light assembly (See SLIDING ROOF SWITCH ASSEMBLY ).

Measure the resistance according to the value(s) in the table below.

Standard Resistance

TESTER CONNECTION SPECIFIED CONDITION CHART

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

NOTE: 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.

NG: REPLACE MAP LIGHT ASSEMBLY (SLIDING ROOF SWITCH ASSEMBLY) (See SLIDING ROOF SWITCH ASSEMBLY )

OK: Go to Next Step

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 SPECIFIED CONDITION CHART

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

NG: REPAIR OR REPLACE HARNESS OR CONNECTOR
