(a) Inspect the relay continuity.
(1) Using an ohmmeter, check that there is continuity between terminals 1 and 2.
If there is no continuity, replace the relay.
(2) Check that there is no continuity between terminals 3 and 5.
If there is continuity, replace the relay.





(b) Inspect the relay operation.
(1) Apply battery positive voltage across terminals 1 and 2.
