Reason for running this test:
• Displayed downforce showing erratic peak highs
• Ride quality is degrading
• Suspected accumulator leaks

IMPORTANT: Before running the accumulator test, IRHD circuit must be connected to tractor power beyond. Test must be performed with at least one SCV in continuous detent position in order to provide high pump pressure.

1. Use the following test for verifying the accumulator pressure on each row unit.

   Select Menu >> Planter button >> Diagnostics button >> Tests tab (A).

2. Select IRHD Tests from the drop-down box (B).

3. Select Accumulator Test (C) from the drop-down list.

4. Input selected row units for the accumulator test using the input boxes (D and E).

5. To start or stop the test, select the Start/Stop button (F).

Test Complete appears on-screen when the accumulator test is completed without failures.

If a row unit fails the test, have your John Deere™ dealer replace the accumulator within the IRHD actuator.
