Yes		ADJUST the A/C compressor clutch air gap. REFER to: Air Conditioning (A/C) Clutch Air Gap Adjustment (412-00 Climate Control System - General Information, General Procedures).
No	INSTALL a new A/C compressor clutch and A/C clutch field coil. REFER to: Air Conditioning (A/C) Clutch and Air Conditioning (A/C) Clutch Field Coil (412-00 Climate Control System - General Information, General Procedures).

G17 CHECK FOR CORRECT FCIM (FRONT CONTROLS INTERFACE MODULE) OPERATION

Disconnect and inspect all FCIM connectors. Repair:

corrosion (install new connector or terminals – clean module pins) damaged or bent pins – install new terminals/pins pushed-out pins – install new pins as necessary

Reconnect all FCIM connectors. Make sure they seat and latch correctly. Operate the system and determine if the concern is still present.

Is the concern still present?

Yes		CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new FCIM. Refer to the appropriate section in Group 415 for the procedure.
No	The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.

G18 CHECK FOR CORRECT PCM (POWERTRAIN CONTROL MODULE) OPERATION

Disconnect and inspect all PCM connectors. Repair:

corrosion (replace connector or terminals – clean module pins) damaged or bent pins – replace terminals/pins pushed-out pins – replace pins as necessary

Reconnect all PCM connectors. Make sure they seat and latch correctly. Operate the system and verify the concern is still present.

Is the concern still present?
