Inspection Procedure

WARNING: This page is about a different car, the 2008 Toyota Tundra. However, it is still accessible from the selected car via links, so may be relevant.
  1. PERFORM ACTIVE TEST USING TECHSTREAM (SLIDING ROOF OPERATION) 
    1. Select the Active Test, use the Techstream to generate a control command, and then check that the sliding roof operates (see DATA LIST / ACTIVE TEST  ).

      Sliding Roof 

      TECHSTREAM SLIDING ROOF - DATA LIST

      Tester Display Test Part Control Range
      Slide Roof Operate sliding roof SLIDE CLOSE/TILT UP or SLIDE OPEN/TILT DOWN CLOS/UP: Sliding roof SLIDE
      CLOSE or TILT UP operation occurs
      OPN/DWN: Sliding roof SLIDE
      OPEN or TILT DOWN operation occurs
      OFF: Sliding roof is not operating

      OK: Sliding roof operates normally. 

    NG: REPLACE SLIDING ROOF DRIVE GEAR SUB-ASSEMBLY (SLIDING ROOF ECU)  (see DISASSEMBLY  )

    OK: Go to Next Step 

  2. READ VALUE USING TECHSTREAM (SLIDING ROOF SWITCH) 
    1. Use the Data List to check if the sliding roof switch is functioning properly (see DATA LIST / ACTIVE TEST  ).

      Open Switch Sliding roof open switch signal/ ON or OFF ON: SLIDE switch is pressed to open
      OFF: SLIDE switch is not pressed to open      		 -
      Close Switch Sliding roof close switch signal/ ON or OFF ON: SLIDE switch is pressed to close
      OFF: SLIDE switch is not pressed to close      		 -
      Up Switch Sliding roof up switch signal/ON or OFF ON: TILT switch is pressed to up
      OFF: TILT switch is not pressed to up      		 -
      Down Switch Sliding roof down switch signal/ ON or OFF ON: TILT switch is pressed to down
      OFF: TILT switch is not pressed to down      		 -

      OK: The Techstream displays as shown in the table according to the operation of each switch. 

    NG: Go to step 3 

    OK: REPLACE SLIDING ROOF DRIVE GEAR SUB-ASSEMBLY (SLIDING ROOF ECU)  (see DISASSEMBLY  )

  3. INSPECT SLIDING ROOF SWITCH 
    1. Remove the sliding roof switch (see REMOVAL  ).
    2. Measure the resistance according to the value(s) in the table below.
