―  Positive battery cable to terminal A, negative battery cable to terminal B

―  Positive battery cable to terminal B, negative battery cable to terminal A

2.  Verify that the spool valve moves in the direction shown in the figure when battery voltage is applied between OCV terminals A and B.

•  If there is any malfunction, replace the OCV.
