2. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   Terminal 1 of the solenoid (SL4) valve - terminal 2	20°C (68°F)	5.0 to 5.6 Ω

3. Connect a positive (+) lead from the battery with a 21 W bulb to terminal 2 and a negative (-) lead to terminal 1 of the solenoid valve connector. Check that the valve moves and makes an operating sound.

   OK

   Valve moves and makes an operating sound.

4. Install the solenoid (SL4) valve.
