1. Ensure that the key switch is in the O
2. Disconnect the wire harness electrical connector from the solenoid valve
coil that is to be tested
3. Identify the coil resistance specification by measuring the coil diameter and
coil height (Figure
Note: Before taking the small resistance readings with a digital multimeter,
short the multimeter test leads together. The multimeter displays a small
resistance value (usually 0.5 ohms or less). This resistance is because of the
internal resistance of the multimeter and test leads. Subtract this value from
the measured value of the component that you are testing.
4. Use a multimeter (ohms setting), measure the resistance between the 2
connector terminals on the solenoid valve coil. The correct resistance for
the solenoid coil is identified in the
(page 5–53).
5. If the solenoid coil resistance is incorrect, replace the solenoid coil; refer to
the Lift Control Manifold Solenoid Valve Coils (page
6. After testing the coils, connect the wire harness electrical connector to the
solenoid valve coil.
