Circuit Opening Relay Inspection:

Inspect Relay Continuity
- Using an ohmmeter, check that there is continuity between terminals STA and E1.
- Check that there is continuity between terminals B and FC.
- Check that there is no continuity between terminals B and FP.
- If continuity is not as specified, replace the relay.

Circuit Opening Relay Inspection:

Inspect Relay Operation
- Apply battery voltage across terminals STA and E1.
- Using an ohmmeter, check that there is continuity between terminals B and FP.
