RELAY ON-VEHICLE INSPECTION

PROCEDURE


  1. INSPECT STARTER RELAY (ST)


    1. A01WQZQE02

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      3 - 5 Battery voltage not applied to terminals 1 and 2 10 kΩ or higher
      Battery voltage applied to terminals 1 and 2 Below 1 Ω

      If the result is not as specified, replace the relay.

  2. INSPECT MAIN BODY ECU (ACC RELAY)

    Tech Tips

    Before performing the relay inspections for the relay of the main body ECU, inspect the ECU-ACC fuse.


    1. Measure the resistance of the ACC relay circuit.


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

        Standard Resistance
        Tester Connection Condition Specified Condition
        2G-1 - 2H-9 Battery voltage not applied between 2J-18 and 2J-1 10 kΩ or higher
        Battery voltage applied between 2J-18 and 2J-1 Below 1 Ω
