INSPECTION PROCEDURE

1.PERFORM ACTIVE TEST USING INTELLIGENT TESTER (SLIDING ROOF OPERATION)

  1. Select the Active Test, use the intelligent tester to generate a control command, and then check that the sliding roof slides open/closed and tilts up/down (Click here).

    		Test Part
    		Control Range
    		Diagnostic Note
    Slide Roof
    		Operate sliding roof SLIDE CLOSE/TILT UP
    		CLOS/UP: Sliding roof SLIDE CLOSE or TILT UP operation occurs
    OFF: Sliding roof is not operating
    		Be careful to avoid injuries as this test causes vehicle parts to move.
    Slide Roof
    		Operate sliding roof SLIDE OPEN/TILT DOWN
    		OPEN/DWN: Sliding roof SLIDE OPEN or TILT DOWN operation occurs
    OFF: Sliding roof is not operating
    		Be careful to avoid injuries as this test causes vehicle parts to move.
OK:
Sliding roof operates normally.

  1. 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)
