GS 430 V8-4.3L (3UZ-FE) (2004)
b. Contact the two leads of an ohmmeter to each of the check points.
If the circuit has diodes, reverse the two leads and check again.
When contacting the negative lead to the diode positive side and the positive lead to the negative side, there should be continuity.
When contacting the two leads in reverse, there should be no continuity.
c. Use a volt/ohmmeter with high impedance (10 kOhms/V minimum) for troubleshooting of the electrical circuit.

DISCONNECTION OF MALE AND FEMALE CONNECTORS
To pull apart the connectors, pull on the connector itself, not the wire harness.
HINT: Check to see what kind of connector you are disconnecting before pulling apart.
