INSPECTION PROCEDURE

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.

      Sliding Roof
      Tester Display 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.

  2. READ VALUE USING INTELLIGENT TESTER (HALL IC)


    1. Use the Data List to check if the hall ICs are functioning properly.

      Sliding Roof
      Item Measurement Item/Range Normal Condition Diagnostic Note
      Hall IC1 Status Hall IC1 status/NORMAL or LOCK

      NORMAL: Hall IC1 is normal.

      LOCK: Hall IC1 is abnormal.

      		 -
      Hall IC1 Pulse Hall IC1 signal/LO or HI

      LO: Hall IC1 output Lo.

      HI: Hall IC1 output Hi.

      		 -
      Hall IC2 Status Hall IC2 status/NORMAL or LOCK

      NORMAL: Hall IC2 is normal.

      LOCK: Hall IC2 is abnormal.

      		 -
      Hall IC2 Pulse Hall IC2 signal/LO or HI

      LO: Hall IC2 output Lo.

      HI: Hall IC2 output Hi.

      		 -
      OK
      Tester displays other than LOCK.

  3. READ VALUE USING INTELLIGENT TESTER (SLIDING ROOF SWITCH)


    1. Use the Data List to check if the sliding roof switch is functioning properly.

      Sliding Roof
      Item Measurement Item/Range Normal Condition Diagnostic Note
      Open Switch Sliding roof switch open signal/ON or OFF

      ON: OPEN switch is pressed

      OFF: OPEN switch is not pressed

      		 -
      Close Switch Sliding roof switch close signal/ON or OFF

      ON: CLOSE switch is pressed

      OFF: CLOSE switch is not pressed

      		 -
      Up Switch Sliding roof switch tilt up signal/ON or OFF

      ON: UP switch is pressed

      OFF: UP switch is not pressed

      		 -
      Down Switch Sliding roof switch tilt down signal/ON or OFF

      ON: DOWN switch is pressed

      OFF: DOWN switch is not pressed

      		 -
      OK
      When the switch is operating, the intelligent tester should display as shown in the table.

  4. INSPECT MAP LIGHT ASSEMBLY (SLIDING ROOF SWITCH)

    A01H189E01

    1. Remove the map light for standard body Click here or long body Click here.

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

      Standard resistance
      Tester Connection Switch Condition Specified Condition
      A-24 (UP) - A-16 (GND9) TILT UP Below 1 Ω
      A-24 (UP) - A-16 (GND9) Off 10 kΩ or higher
      A-23 (DOWN) - A-16 (GND9) TILT DOWN Below 1 Ω
      A-23 (DOWN) - A-16 (GND9) Off 10 kΩ or higher
      B-3 (OPN) - A-16 (GND9) SLIDE OPEN Below 1 Ω
      B-3 (OPN) - A-16 (GND9) Off 10 kΩ or higher
      B-12 (CLS) - A-16 (GND9) SLIDE CLOSE Below 1 Ω
      B-12 (CLS) - A-16 (GND9) Off 10 kΩ or higher
