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


    1. Disconnect the A37 or A46 ECM connector.

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

      Standard Resistance
      for 2GR-FKS
      Tester Connection Condition Specified Condition
      J12-13 (TC) - A37-33 (TC) Always Below 1 Ω
      J12-13 (TC) or A37-33 (TC) - Body ground Always 10 kΩ or higher
      Standard Resistance
      for 8AR-FTS
      Tester Connection Condition Specified Condition
      J12-13 (TC) - A46-33 (TC) Always Below 1 Ω
      J12-13 (TC) or A46-33 (TC) - Body ground Always 10 kΩ or higher
