5. Verify that the spool valve inside the OCV is at the position shown in the figure (position where it is pulled).
- If it cannot be verified, replace the OCV.
6. Verify that the battery is fully charged.
NOTE:
- When applying battery positive voltage between the oil control valve terminals, the connection of the negative and positive cable can be either the A or B terminal.
7. Verify that the spool valve moves to the position shown in the figure (position where it projects) when battery positive voltage is applied between terminals A and B.
- If it cannot be verified, replace the OCV.
8. Stop applying battery positive voltage and verify that the spool valve returns to the original position.
- If it cannot be verified, replace the OCV.
