      NOTE:
      • Check that the battery voltage is between 10 and 16 V before performing this test.
      • Perform this test within 10 seconds to prevent the coil from burning out.
      • Always switch the voltage on and off at the battery side, not the oil pressure control valve assembly side.

      If the result is not as specified, replace the oil pressure control valve assembly.
