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 indicated in the figure.
If not as specified, replace the OCV..
3. Verify that the battery is fully charged..
If not as specified, recharge the battery..
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
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..
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..

Tire Rotation
WARNING
Rotate tires periodically:
Irregular tire wear is dangerous. To
equalize tread wear for maintaining
good performance in handling and
braking, rotate the tires every 12,000
km (7,500 miles). However Mazda
recommends to rotate every 8,000 km
(5,000 miles) to help ...
