7	CHARGING SYSTEM WARNING LIGHT ILLUMINATED/MESSAGE RELATED TO CHARGING SYSTEM MALFUNCTION INDICATED IN DISPLAY
DESCRIPTION	•  Charging system warning light illuminated. •  Message related to charging system malfunction indicated on the center display. (With center display) •  Message related to charging system malfunction indicated on the LCD in the instrument cluster. (Type A instrument cluster)
POSSIBLE CAUSE	•  Erratic signal to PCM ―  Generator or related circuit malfunction •  Battery malfunction •  Generator malfunction •  Instrument cluster malfunction

Diagnostic Procedure

STEP	INSPECTION	RESULTS	ACTION
1	VERIFY PCM DTC •  Retrieve PCM DTCs using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-D 2.2].) •  Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [SKYACTIV-D 2.2].)
		No	Go to the next step.
2	VERIFY CURRENT INPUT SIGNAL STATUS Caution •  While performing this step, always operate the vehicle in a safe and lawful manner. •  When the M-MDS is used to observe monitor system status while driving, be sure to have another technician with you, or record the data in the M-MDS using the PID/DATA MONITOR AND RECORD capturing function and inspect later. •  Access the following PIDs using the M-MDS: (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-D 2.2].) ―  ALTT V •  Do the PIDs indicate the correct values under the trouble condition? (See PCM INSPECTION [SKYACTIV-D 2.2].)	Yes	Inspect the related sensor and circuit. •  If there is any malfunction: ―  Repair or replace the malfunctioning part according to the inspection results, then go to Step 6. •  If there is no malfunction: ―  Go to the next step.
		No	Go to the next step.
3	INSPECT BATTERY •  Inspect the battery. (See BATTERY INSPECTION [SKYACTIV-D 2.2].) •  Is the battery normal?	Yes	Go to the next step.
		No	Recharge or replace the battery, then go to Step 6. (See BATTERY RECHARGING [SKYACTIV-D 2.2].) (See BATTERY REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
4	INSPECT GENERATOR •  Inspect the generator. (See GENERATOR INSPECTION [SKYACTIV-D 2.2 (WITHOUT i-ELOOP)].) (See GENERATOR INSPECTION [SKYACTIV-D 2.2 (WITH i-ELOOP)].) •  Is the generator normal?	Yes	Go to the next step.
		No	Repair or replace the malfunctioning part according to the inspection results, then go to Step 6. (See GENERATOR REMOVAL/INSTALLATION [SKYACTIV-D 2.2 (WITHOUT i-ELOOP)].) (See GENERATOR REMOVAL/INSTALLATION [SKYACTIV-D 2.2 (WITH i-ELOOP)].)
5	INSPECT INSTRUMENT CLUSTER •  Inspect the instrument cluster. (See INSTRUMENT CLUSTER INSPECTION.) •  Is the instrument cluster normal?	Yes	Go to the next step.
		No	Replace the instrument cluster, then go to the next step. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
6	Verify the test results. •  If normal, return to the diagnostic index to service any additional symptoms. (See SYMPTOM DIAGNOSTIC INDEX [SKYACTIV-D 2.2].) •  If a malfunction remains, inspect the related Service Information and perform the repair or diagnosis. ―  If the vehicle is repaired, troubleshooting is completed. ―  If the vehicle is not repaired or additional diagnostic information is not available, replace the PCM. (See PCM REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
