INSPECTION
1. REMOVE CIRCUIT OPENING RELAY
2. INSPECT CIRCUIT OPENING RELAY CONTINUITY
DENSO made:

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.
BOSCH made:
(1) Using an ohmmeter, check that there is continuity between terminals 85 and 86.
If there is no continuity, replace the relay.
(2) Check that there is no continuity between terminals 30 and 87.
If there is continuity, replace the relay.
3. INSPECT CIRCUIT OPENING RELAY OPERATION
