Carry Out The KOER On-Demand Self-Test

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2006 Ford RV Cutaway, 2006 Ford Pickup, 2006 Ford F550 Super Duty, 2006 Ford F450 Super Duty, and 2006 Ford Econoline. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Before carrying out the KOER On-Demand Self-Test make sure the high pressure oil passages are free of air. A recent repair to the system may allow air to enter the oil passages. To remove the air, drive the vehicle (with deceleration and acceleration cycles) at highway speeds for 32 km (20 miles).
