Test 9: Perform KOER On-Demand Self-Test: Notes

NOTE: Before performing KOER ON-DEMAND SELF-TEST make sure high-pressure oil passages are free of air. A recent repair to system may allow air to enter oil passages. To remove air, drive vehicle through deceleration and acceleration cycles at highway speeds for 20 miles.
