Symptom Chart: Climate Control - Electronic Manual Temperature Control (EMTC)
WARNING: This page is about a different car, the 2017 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
Diagnostics in this service information assume a certain skill level and knowledge of Ford-specific diagnostic practices. REFER to: Diagnostic Methods .
Symptom Chart
| Condition | Possible Sources | Actions |
|---|---|---|
| A module does not communicate with the diagnostic scan tool | Fuse(s) Wiring, terminals or connectors FCIM |
REFER to: Communications Network . |
| Unable To Duplicate The Customer Concern And No Diagnostic Trouble Codes (DTCs) Present | Refer to Pinpoint Test | GO to Pinpoint Test C |
| HVAC functions are inoperative or do not operate correctly from touchscreen only | Communication network FCIM APIM |
REFER to: Information and Entertainment System - Vehicles With: Touchscreen Display. |
| Reduced outlet airflow | Plugged cabin air filter | INSPECT the cabin air filter. REFER to: Cabin Air Filter . If OK, DIAGNOSE for low refrigerant charge, A/C always commanded on or blower motor not operating correctly. |
| Improper refrigerant level | CARRY OUT the refrigerant system tests. REFER to: Refrigerant System Tests - 2.0L EcoBoost (184kW/250PS) - MI4 . REFER to: Refrigerant System Tests - 2.7L EcoBoost (238kW/324PS) . REFER to: Refrigerant System Tests - 3.5L Duratec (212kW/278PS) . If refrigerant charge is OK, GO to Pinpoint Test H | |
| Blower motor | GO to Pinpoint Test K | |
| The air inlet door is inoperative | Refer to Pinpoint Test | GO to Pinpoint Test D |
| Incorrect/erratic direction of airflow from outlets | Refer to Pinpoint Test | GO to Pinpoint Test E |
| Insufficient, erratic or no heat | Refer to Pinpoint Test | GO to Pinpoint Test F |
| Insufficient heat in Auto Start-Stop mode only | Refer to Pinpoint Test | GO to Pinpoint Test P |
| The A/C is inoperative | Refer to Pinpoint Test | GO to Pinpoint Test G |
| Insufficient A/C cooling | Improper refrigerant level | CARRY OUT the refrigerant system tests. REFER to: Refrigerant System Tests - 2.0L EcoBoost (184kW/250PS) - MI4 . REFER to: Refrigerant System Tests - 2.7L EcoBoost (238kW/324PS) . REFER to: Refrigerant System Tests - 3.5L Duratec (212kW/278PS) . If OK, DIAGNOSE for a temperature door actuator not operating correctly. |
| Temperature door actuator | GO to Pinpoint Test I | |
| The A/C is always on - A/C mode always commanded ON | Refer to Pinpoint Test | GO to Pinpoint Test H |
| Temperature control is inoperative/does not operate correctly | Refer to Pinpoint Test | GO to Pinpoint Test I |
| The blower motor is inoperative | Refer to Pinpoint Test | GO to Pinpoint Test J |
| The blower motor does not operate correctly | Refer to Pinpoint Test | GO to Pinpoint Test K |
| A/C pressure relief valve discharging | A/C pressure relief valve | CHECK the high side system pressure. If the pressure is below the A/C pressure relief valve open pressure (500-600 psi), INSTALL a new A/C Compressor. For 2.0L, REFER to: Air Conditioning (A/C) Compressor - 2.0L EcoBoost (184kW/250PS) - MI4 . For 2.7L, REFER to: Air Conditioning (A/C) Compressor - 2.7L EcoBoost (238kW/324PS) . For 3.5L, REFER to: Air Conditioning (A/C) Compressor - 3.5L Duratec (212kW/278PS) . |
| High system pressure | CHECK the high side system pressure. If the system pressure is above the A/C pressure relief valve open pressure (500-600 psi), REPAIR the A/C system for a restriction. | |
| Climate control does not operate only when remote start is used | IPC information display settings Non-Ford approved remote start system installed |
VERIFY Remote Start - Message Center Set To Auto, or Remote Start - Message Center Set To Last User Settings. REFER to: Climate Control System - Vehicles With: Electronic Manual Temperature Control (EMTC) - System Operation and Component Description . VERIFY module communications network operation. DIAGNOSE Diagnostic Trouble Codes (DTCs) if present. |
