  4. CHECK HARNESS AND CONNECTOR (TC of DLC3 - ECM)


    1. Turn the ignition switch off.

    2. for 1KD-FTV (w/o DPF):


      1. Disconnect the B72 ECM connector.

    3. for 1KD-FTV (w/ DPF):


      1. Disconnect the B73 ECM connector.

    4. for 2KD-FTV:


      1. Disconnect the B88 ECM connector.

    5. for 1TR or 2TR-FE (w/ Dual VVT-i):


      1. Disconnect the B94 ECM connector.

    6. for 2TR-FE (except Dual VVT-i):


      1. Disconnect the B71 ECM connector.

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

      Standard Resistance
      for 1KD-FTV (w/o DPF):
      Tester Connection Condition Specified Condition
      B72-26 (TC) - H23-13 (TC) Always Below 1 Ω
      B72-26 (TC) or H23-13 (TC) - Body ground Always 10 kΩ or higher
      for 1KD-FTV (w/ DPF):
      Tester Connection Condition Specified Condition
      B73-26 (TC) - H23-13 (TC) Always Below 1 Ω
      B73-26 (TC) or H23-13 (TC) - Body ground Always 10 kΩ or higher
      for 2KD-FTV:
      Tester Connection Condition Specified Condition
      B88-26 (TC) - H23-13 (TC) Always Below 1 Ω
      B88-26 (TC) or H23-13 (TC) - Body ground Always 10 kΩ or higher
      for 1TR or 2TR-FE (w/ Dual VVT-i):
      Tester Connection Condition Specified Condition
      B94-33 (TC) - H23-13 (TC) Always Below 1 Ω
      B94-33 (TC) or H23-13 (TC) - Body ground Always 10 kΩ or higher
      for 2TR-FE (except Dual VVT-i):
      Tester Connection Condition Specified Condition
      B71-41 (TC) - H23-13 (TC) Always Below 1 Ω
      B71-41 (TC) or H23-13 (TC) - Body ground Always 10 kΩ or higher
