1. INSPECT TURBOCHARGER SUB-ASSEMBLY


  1. Check the resistance.



      A200305E01
    1. Measure the resistance according to the value(s) in the table below.
      *1
      Component without harness connected
      (DC Motor)

      Standard Resistance:
      Tester Connection
      Condition
      Specified Condition
      1 (M-) - 2 (M+)
      Always
      0.3 to 100 Ω

      If the result is not as specified, replace the turbocharger sub-assembly.



2. VISUALLY CHECK TURBOCHARGER SUB-ASSEMBLY


    A227159E01
  1. Check for deformation and cracks in the turbine wheel on the exhaust side.
    If the turbine wheel is cracked or deformed, replace the turbocharger sub-assembly.

    *1
    Turbine Wheel



3. CHECK TURBINE SHAFT ROTATION


    A230522
  1. Rotate the turbine wheel on the exhaust side with your finger and check that it rotates smoothly.

    HINT:
    Even if it takes effort a little to rotate the turbine wheel, this is not a problem.

    If the turbine wheel does not rotate smoothly, replace the turbocharger sub-assembly.



    A227160
  1. Move the turbine wheel as shown in the illustration and check that there is no looseness* in the shaft and it does not contact the housing.
    If there is any contact with the housing or obvious looseness in the shaft, replace the turbocharger sub-assembly.

    HINT:
    *: A clearance on the order of 100 μm exists between the turbine shaft and bearings. If it is difficult to judge the looseness of turbine shaft, perform same inspection on another vehicle which has the same turbocharger and compare the clearance.
