a) Plug port (C) with your finger and apply pressure to port (B).
Make sure there is circulation between ports (B) and (A).
b) Plug port (C) with your finger and apply vacuum to port (B).
Make sure there is circulation between ports (B) and (A).
3. Check the solenoid valve.
a) Make sure there is no circulation between the ports.
b) Apply battery voltage to the terminals of the solenoid valve.
Make sure there is circulation between the ports.
c) Check the resistance between the terminals of the solenoid valve.
- Nominal resistance (at 20°C) - 32 Ohm
