Spool Valve Operation Inspection
- Remove the OCV. (See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION .)
- Verify that the spool valve in the OCV is in the maximum valve timing retard position as indicated in the figure.
- Verify that the battery is fully charged. (See BATTERY RECHARGING [MZR 2.5]
.)
- Apply battery positive voltage between the OCV terminals and verify that the spool valve operates and moves to the maximum valve timing advance position.
NOTE:
- When applying battery positive voltage between the OCV terminals, the connection can be either of the following:
- Positive battery cable to terminal A, negative battery cable to terminal B
- Positive battery cable to terminal B, negative battery cable to terminal A
- Stop applying battery positive voltage and verify that the spool valve returns to the maximum valve timing retard position.
- Install the OCV. (See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION .)
