Solenoid Valve
Apply appropriately fused battery voltage and ground to the solenoid terminals 6 and 4 and verify that the valve opens and closes completely as voltage is applied to and removed from the solenoid terminals. Observe that the valve is not obstructed or leaking.
- If the valve operates incorrectly, leaks, or is obstructed, remove the obstruction or replace the AIR solenoid.
