Coil Resistance Inspection
1. Remove the battery cover..
2. Disconnect the negative battery cable..
3. Disconnect the OCV connector.
4. Measure the coil resistance between terminals A and B using a tester.
If not as specified, replace the OCV..
6.9—7.9 ohms [20°C {68°F}]
5. Install in the reverse order of removal.
Spool Valve Operation Inspection
1. Remove the OCV..
2. Verify that the spool valve in the OCV is in the maximum valve timing retard position as shown in the figure.
If not as specified, replace the OCV..
3. Verify that the battery is fully charged..
Recharge it if necessary..
4. Apply battery positive voltage between the OCV terminals and verify that the spool valve operates and moves to the maximum valve timing advance position.
If not as specified, replace the OCV..
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
5. Stop applying battery positive voltage and verify that the spool valve returns to the maximum valve timing retard position.
If not as specified, replace the OCV..
6. Install the OCV..
