Diagnostic Procedure

Step	Inspection		Action
1	VERIFY FRONT BODY CONTROL MODULE (FBCM) DTCs AGAIN • Clear the DTC for the front body control module (FBCM) using the M-MDS. (See CLEARING DTC [FRONT BODY CONTROL MODULE (FBCM)].) • Switch the ignition ON (engine off or on) and wait for 5 s or more. • Retrieve the front body control module (FBCM) DTCs using the M-MDS. (See DTC INSPECTION [FRONT BODY CONTROL MODULE (FBCM)].) • Is the same Pending DTC present?	Yes	Go to the next step.
1		No	Go to Step 4.
2	INSPECT CURRENT SENSOR • Inspect the current sensor. (See CURRENT SENSOR INSPECTION [SKYACTIV-D 2.2].) (See CURRENT SENSOR INSPECTION [SKYACTIV-G 2.5T].) (See CURRENT SENSOR INSPECTION [SKYACTIV-G 2.5 (WITH CYLINDER DEACTIVATION)].) (See CURRENT SENSOR INSPECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5 (WITHOUT CYLINDER DEACTIVATION)].) • Is the current sensor normal?	Yes	Go to the next step.
2		No	Replace the current sensor, then go to the next step. (See CURRENT SENSOR REMOVAL/INSTALLATION [SKYACTIV-D 2.2].) (See CURRENT SENSOR REMOVAL/INSTALLATION [SKYACTIV-G 2.5T].) (See CURRENT SENSOR REMOVAL/INSTALLATION [SKYACTIV-G 2.5 (WITH CYLINDER DEACTIVATION)].) (See CURRENT SENSOR REMOVAL/INSTALLATION [SKYACTIV-G 2.0, SKYACTIV-G 2.5 (WITHOUT CYLINDER DEACTIVATION)].)
3	VERIFY THAT REPAIRS HAVE BEEN COMPLETED • Clear the DTC for the front body control module (FBCM) using the M-MDS. (See CLEARING DTC [FRONT BODY CONTROL MODULE (FBCM)].) • Switch the ignition ON (engine off or on) and wait for 5 s or more. • Retrieve the front body control module (FBCM) DTCs using the M-MDS. (See DTC INSPECTION [FRONT BODY CONTROL MODULE (FBCM)].) • Is the same Pending DTC present?	Yes	Replace the front body control module (FBCM). (See FRONT BODY CONTROL MODULE (FBCM) REMOVAL/INSTALLATION.) Go to the next step.
3		No	Go to the next step.
4	VERIFY IF OTHER DTCs DISPLAYED • Are any other DTCs displayed?	Yes	Repair or replace the malfunctioning part according to the applicable DTC troubleshooting. (See DTC TABLE [FRONT BODY CONTROL MODULE (FBCM)].)
4		No	DTC troubleshooting completed.
