1. REMOVE CIRCUIT OPENING RELAY
LOCATION: In the engine compartment relay box. (Marking: CIR OPN)
2. INSPECT CIRCUIT OPENING RELAY





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





B. Inspect relay operation
(a) Apply battery voltage across terminals 1 and 2.
(b) Using an ohmmeter, check that there is continuity between terminals 3 and 5.
If there is no continuity, replace the relay.
3. REINSTALL CIRCUIT OPENING RELAY
