      Activate the EVAP Purge VSV
    5. When the purge VSV (No. 1 vacuum switching valve assembly) is operated using the GTS, check whether the port of the purge VSV (No. 1 vacuum switching valve assembly) applies suction your finger.

      OK

      GTS Operation Specified Condition
      ON Purge VSV (No. 1 vacuum switching valve assembly) port applies suction to finger
      OFF Purge VSV (No. 1 vacuum switching valve assembly) port applies no suction to finger

      HINT: 

      Jiggle the wire harness and connector to increase the likelihood of detecting malfunctions that do not always occur.
