      Standard Resistance

      Tester Connection Condition Specified Condition
      3 - 5 Auxiliary battery voltage not applied between terminals 1 and 2 10 kΩ or higher
      Auxiliary battery voltage applied between terminals 1 and 2 Below 1 Ω

      If the result is not as specified, replace the main relay (EFI-MAIN NO. 1).

  2. INSPECT MAIN RELAY (EFI-MAIN NO. 2) 
    1. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition
      3 - 5 Auxiliary battery voltage not applied between terminals 1 and 2 10 kΩ or higher
      Auxiliary battery voltage applied between terminals 1 and 2 Below 1 Ω

      If the result is not as specified, replace the VVT relay (VVT).

  6. INSPECT NO. 2 IGNITION RELAY (IG2 NO. 1) 
    1. Measure the resistance according to the value(s) in the table below.
      GTY751946Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002

      Standard Resistance

      Tester Connection Condition Specified Condition
      3 - 5 Auxiliary battery voltage not applied between terminals 1 and 2 10 kΩ or higher
      Auxiliary battery voltage applied between terminals 1 and 2 Below 1 Ω

      If the result is not as specified, replace the No. 2 ignition relay (IG2 NO. 1).
