Reasons for running this test:
• Performance bars are showing red instead of black
• Valves are not meeting performance requirements

IMPORTANT: Before running the valve test, Individual Row Hydraulic Downforce (IRHD) circuit must be connected to the tractor power beyond. At least one SCV must be in continuous detent position in order to provide high pump pressure during the test.
