M2 CHECK FOR CORRECT HVAC (HEATING, VENTILATION AND AIR CONDITIONING) CONTROL MODULE OPERATION
- Ignition OFF.
- Disconnect and inspect the HVAC control module 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 the HVAC control module connectors. Make sure they seat and latch correctly.
- Operate the system and verify the concern is still present.
Is the concern still present?
1. Yes: CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, discontinue this test and follow TSB. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new HVAC control module.
  REFER to: Heating, Ventilation and Air Conditioning (HVAC) Control Module .
2. No: The system is operating correctly at this time. The concern may have been caused by module connections. Address the root cause of any connector or pin issues.
