Note: Diagnose all crankshaft position (CKP) sensor, camshaft position (CMP) sensor, glow plug system or high pressure oil system DTCs before entering this pinpoint test.
Note: For E-Series, the scan tool may have a delayed response in displaying the FICM_LPWR and FICM_VPWR PIDs actual values. If the peak voltage values meet the specification the vehicle should start and run normally.
Note: The fuel injectors will click for approximately 20 seconds after the ignition is turned to the ON position. The fuel injectors cycling for approximately 20 seconds is an indication that the FICM is operating correctly.
