      Standard voltage

      Tester Connection Switch Condition Specified Condition
      E1-18 (VC) - E2-33 (VV1-) Engine switch on (IG) 5 V
      E1-18 (VC) - E4-29 (VV2-) Engine switch on (IG) 5 V
      E1-18 (VC) - E1-33 (EV1-) Engine switch on (IG) 5 V
      E1-18 (VC) - E3-29 (EV2-) Engine switch on (IG) 5 V
    3. While turning the crankshaft pulley by hand, measure the voltage between each terminal. Check that the voltage changes between the Hi range and Lo range shown in the table below.
