Circuit Opening Relay
- Circuit opening relay is located behind center console of instrument panel. Relay is mounted on bracket attached to ECM. Relay contains a 6-pin Black connector.
- Disconnect electrical connector from circuit opening relay. Using ohmmeter, ensure continuity exists between Black/Orange and White/Black wire terminals and Black/Red and Green/Red wire terminals.
- Ensure no continuity exists between Black/Red and Blue/Black wire terminals. Replace circuit opening relay if continuity is not as specified.
- Apply battery voltage to Black wire terminal and ground White/Black wire terminal. Ensure continuity exists between Black/Red and Blue/Black wire terminals. Disconnect battery voltage.
- Apply battery voltage to Black/Red wire terminal and ground Green/Red wire terminal. Ensure continuity exists between Black/Red and Blue/Black wire terminals. Disconnect battery voltage. Replace circuit opening relay if defective.
