INSPECT A\/C COMPRESSOR FOR INTERFERENCE NOISE<\/div>\n
\u2022 Is there a rattling or vibrating sound (interference noise)?<\/div>\n<\/td>\n
\n
Yes<\/div>\n<\/td>\n
\n
Go to Step 7.<\/div>\n<\/td>\n<\/tr>\n
\n
No<\/div>\n<\/td>\n
\n
Go to the next step.<\/div>\n<\/td>\n<\/tr>\n
\n
3<\/div>\n<\/td>\n

\u2022 Is there a jingling, popping, beeping, or buzzing sound (A\/C compressor vane noise)?<\/div>\n<\/td>\n
\n
Yes<\/div>\n<\/td>\n
\n
Replace the magnetic clutch, then perform the repair completion verification.<\/div>\n
(See MAGNETIC CLUTCH DISASSEMBLY\/ASSEMBLY [SKYACTIV-G 2.0, SKYACTIV-G 2.5]<\/a>.)<\/div>\n<\/td>\n<\/tr>\n
\n
No<\/div>\n<\/td>\n
\n
Normal (Verify malfunction symptom.)<\/div>\n<\/td>\n<\/tr>\n
\n
4<\/div>\n<\/td>\n
\n
INSPECT DRIVE BELT<\/div>\n
\u2022 Inspect the drive belt. (See DRIVE BELT INSPECTION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))]<\/a>.) (See DRIVE BELT INSPECTION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))]<\/a>.)<\/div>\n
\u2022 Is it normal?<\/div>\n<\/td>\n
\n
Yes<\/div>\n<\/td>\n
\n
Go to the next step.<\/div>\n<\/td>\n<\/tr>\n
\n
No<\/div>\n<\/td>\n
\n
After adjusting the drive belt tension, go to the next step.<\/div>\n
(See DRIVE BELT REMOVAL\/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))]<\/a>.)<\/div>\n
(See DRIVE BELT REMOVAL\/INSTALLATION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))]<\/a>.)<\/div>\n<\/td>\n<\/tr>\n
\n
5<\/div>\n<\/td>\n
\n
INSPECT DRIVE BELT<\/div>\n
\u2022 Is there drive belt deterioration, foreign matter penetration in the belt, or oil on the belt?<\/div>\n<\/td>\n
\n
Yes<\/div>\n<\/td>\n
\n
Remove obstruction, remove oil, or replace drive belt, then perform the repair completion verification.<\/div>\n
(See DRIVE BELT REMOVAL\/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))]<\/a>.)<\/div>\n
(See DRIVE BELT REMOVAL\/INSTALLATION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))]<\/a>.)<\/div>\n<\/td>\n<\/tr>\n
\n
No<\/div>\n<\/td>\n
\n
Go to the next step.<\/div>\n<\/td>\n<\/tr>\n
\n
6<\/div>\n<\/td>\n
\n
INSPECT MAGNETIC CLUTCH<\/div>\n
\u2022 Inspect the magnetic clutch. (See MAGNETIC CLUTCH INSPECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5]<\/a>.)<\/div>\n
\u2022 Is the magnetic clutch normal?<\/div>\n<\/td>\n
\n
Yes<\/div>\n<\/td>\n
\n
Replace A\/C compressor (excluding pressure plate, A\/C compressor pulley, and stator), then perform the repair completion verification.<\/div>\n

\n
7<\/div>\n<\/td>\n
\n
VERIFY LOCATION OF ABNORMAL NOISE OCCURRENCE<\/div>\n
\u2022 Is noise emitted from A\/C compressor?<\/div>\n<\/td>\n
\n
Yes<\/div>\n<\/td>\n
\n
Visually inspect A\/C compressor, replace appropriate parts if necessary, then perform the repair completion verification.<\/div>\n
(See A\/C COMPRESSOR REMOVAL\/INSTALLATION [SKYACTIV-G 2.0, SKYACTIV-G 2.5]<\/a>.)<\/div>\n
(See MAGNETIC CLUTCH DISASSEMBLY\/ASSEMBLY [SKYACTIV-G 2.0, SKYACTIV-G 2.5]<\/a>.)<\/div>\n<\/td>\n<\/tr>\n
\n
No<\/div>\n<\/td>\n
\n
If abnormal noise occurs from the hose or system piping, perform repairs in the area causing interference with the hose or system piping due to clip removal or screw looseness, then perform the repair completion verification.<\/div>\n<\/td>\n<\/tr>\n
\n
Repair completion verification<\/div>\n<\/td>\n
\n
VERIFY THAT MALFUNCTION SYMPTOM DOES NOT RECUR AFTER REPAIR<\/div>\n
\u2022 Has A\/C compressor noise stopped?<\/div>\n<\/td>\n
\n
Yes<\/div>\n<\/td>\n
\n
Troubleshooting completed.<\/div>\n
Explain repairs to customer.<\/div>\n<\/td>\n<\/tr>\n
\n
No<\/div>\n<\/td>\n
\n
Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error.<\/div>\n
(See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [(US)]<\/a>.)<\/div>\n
If the CAN communication is normal, perform the diagnosis from Step 1.<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n
