  1. Disconnect electrical connector from PAIR VSV. See Figure, Figure and Figure. Using ohmmeter, ensure resistance between electrical terminals of VSV is within 37-44 ohms @ 68°F (20°C).
  2. Ensure no continuity exists between each electrical terminal and body of VSV. Apply air pressure to port "E". Ensure air passes out port "P". Perform STEP 1. See Fig 1.
  3. Connect battery voltage and ground to VSV terminals. Apply air pressure to port "E". Ensure air passes out port "F". Perform STEP 2. See Fig 1. Replace VSV if defective.
