Recommended Procedure

WARNING: This page is about a different car, the 2003 Ford Pickup, 2003 Ford F550 Super Duty, 2003 Ford F450 Super Duty, 2003 Ford Excursion, and 2003 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: If no DTCs are present or the test does not complete, go to the next step.

NOTE: This test determines if the injector circuits and solenoids are electrically operating without fault. All injectors will first click together for approximately 2 seconds, then each injector will click for approximately 1 second in numerical order (1 through 8). If a fault is detected, a DTC will be output on the data link at the end of the test when requested by a scan tool. Only a hard fault DTC will be displayed.

To perform self-test, turn ignition off. Ensure test equipment is properly attached. If vehicle is equipped with an auxiliary powertrain control system (RPM control), it must be turned off before performing self-test. Using NGS tester, perform the following steps:

Perform necessary vehicle preparation and visual inspection. See QUICK TEST in SELF-DIAGNOSTICS - 6.0L DIESEL article.
Refer to the scan tool manufacturer manual for scan tool instructions.
Select KOEO INJECTOR ELECTRICAL SELF-TEST (CLICK TEST).
Follow operating instructions from the menu.
Record DTCs and perform appropriate system test. See DIAGNOSTIC TROUBLE CODE DEFINITIONS in SELF-DIAGNOSTICS - 6.0L DIESEL article.
After test has been completed, cycle ignition off before performing other self-tests or driving vehicle.
