VSV For Pressure Switching Valve: Inspection

REMOVE VSV
INSPECT VSV
1. Inspect the VSV for open circuit.
  Using an ohmmeter, measure the resistance between the terminals.
  
  Resistance: 30 to 36 Ω at 20°C (68°F)

  If the result is not as specified, replace the VSV.
2. Inspect the VSV for ground.
  Using an ohmmeter, check that there is no continuity between each terminal and the VSV body.

  If the result is not as specified, replace the VSV.
3. Inspect the VSV operation.
  1. Check that air does not flow from ports E to F.

  2. Apply battery positive voltage to the terminals.
  3. Check that air flows from ports E to F.
  If the operation is not as specified, replace the VSV.
