Test 8: KOEO Injector Electrical Self-Test: Purpose
WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2003 Ford RV Cutaway, 2003 Ford Pickup, 2003 Ford F550 Super Duty, 2003 Ford F450 Super Duty, and 2003 Ford Excursion. However, it is still accessible from the selected car via links, so may be relevant.
The purpose of this test is to determine if injector solenoids and valves are operating properly by buzzing all injectors together for about 2 seconds, then each injector will buzz for about one second in numerical order (1-8). Injector Driver Module (IDM) stores all history IDM DTCs. To ensure DTC is a hard fault, you must first clear Continuous Memory DTCs (ensure all IDM DTCs are recorded before clearing). After clearing, repeat self-test. A fault must be present at time of testing for KOEO INJECTOR ELECTRICAL SELF-TEST to detect fault. If a fault is detected, a DTC will be output at end of test when requested by a scan tool. Only a hard fault DTC will be displayed.
