Leak Detection Solenoid: Testing and Inspection

INSPECTION




1. REMOVE VSV

2. INSPECT VSV
a. Inspect the VSV for open circuit.
Using an ohmmeter, check that there is continuity between the terminals.

Resistance: 25 - 30 Ohms at 20°C (68°F)

If there is no continuity, replace the VSV.




b. Inspect the VSV for ground.
Using an ohmmeter, check that there is no continuity between each terminal and the body.
If there is no continuity, replace the VSV.

c. Inspect the VSV for operation.




1. Check that air flows from ports E to F.




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

3. REINSTALL VSV
