Power Vent Window Motor Circuit: Procedure

1. Disconnect the power quarter window switch connector.
2. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   D3-5 (E) - Body ground	Always	Below 1 Ω

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

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

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

   Standard Resistance

   Tester Connection	Switch Condition	Specified Condition
   D3-1 (B) - D3-3 (OPEN)	Open position → Close position	Below 1 Ω → 10 kΩ or higher
   D3-1 (B) - D3-4 (CLS)	Open position → Close position	10 kΩ or higher → Below 1 Ω
   D3-3 (OPEN) - D3-5 (E)	Open position → Close position	10 kΩ or higher → Below 1 Ω
   D3-4 (CLS) - D3-5 (E)	Open position → Close position	Below 1 Ω → 10 kΩ or higher

OK: Go to next step 

1. Disconnect the power vent window motor assembly LH and RH connector.
2. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   D3-3 (OPEN) - K15-1 (OPEN)	Always	Below 1 Ω
   D3-4 (CLS) - K15-2 (CLS)	Always	Below 1 Ω
   D3-3 (OPEN) - L28-1 (OPEN)	Always	Below 1 Ω
   D3-4 (CLS) - L28-2 (CLS)	Always	Below 1 Ω
   D3-3 (OPEN) - Body ground	Always	10 kΩ or higher
   D3-4 (CLS) - Body ground	Always	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Check the operation of the rear quarter power window control system.

   Result

   Result	Proceed to
