Symptom Chart: Climate Control - Electronic Manual Temperature Control (EMTC)
Diagnostics in this article assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to : Diagnostic Methods .
| Condition | Possible Sources | Actions |
|---|---|---|
| Unable to duplicate the customer concern | Refer to the Pinpoint Test | GO to Pinpoint Test C |
| No communication with the HVAC control module (1. 0L only) | Fuse(s) Wiring, terminals or connectors HVAC control module |
Refer to : Communications Network . |
| Externally Controlled Variable Displacement Compressor (EVDC) poor performance/does not operate correctly | Refer to the Pinpoint Test | GO to Pinpoint Test T |
| Reduced outlet airflow | Plugged cabin air filter | INSPECT the cabin air filter. Refer to : Cabin Air Filter . If OK, DIAGNOSE for low refrigerant charge, AC always commanded on or blower motor not operating correctly. |
| Improper refrigerant level | CARRY OUT the refrigerant system tests. Refer to : Refrigerant System Tests - 1. 0L EcoBoost (92kW/125PS) . Refer to : Refrigerant System Tests - 2. 0L Duratec-HE (125kW/170PS) - MI4/2. 0L EcoBoost (184kW/250PS) - MI4 . If refrigerant charge is OK, GO to Pinpoint Test I | |
| Refer to the Pinpoint Test | GO to Pinpoint Test L | |
| The air inlet door is inoperative | Refer to the Pinpoint Test | GO to Pinpoint Test D |
| Incorrect/erratic direction of airflow from outlets | Refer to the Pinpoint Test | GO to Pinpoint Test E |
| Insufficient Air Conditioning (A/C) cooling | Improper refrigerant level | CARRY OUT the refrigerant system tests. Refer to : Refrigerant System Tests - 1. 0L EcoBoost (92kW/125PS) . Refer to : Refrigerant System Tests - 2. 0L Duratec-HE (125kW/170PS) - MI4/2. 0L EcoBoost (184kW/250PS) - MI4 . If OK, DIAGNOSE for a temperature door actuator not operating correctly. |
| Refer to the Pinpoint Test | GO to Pinpoint Test J | |
| Insufficient, erratic or no heat | Refer to the Pinpoint Test | GO to Pinpoint Test F |
| The electric booster heater is inoperative or does not operate correctly | Refer to the Pinpoint Test | GO to Pinpoint Test O |
| The Air Conditioning (A/C) is inoperative | Refer to the Pinpoint Test | GO to Pinpoint Test G |
| The Air Conditioning (A/C) is always on | Refer to the Pinpoint Test | GO to Pinpoint Test H |
| The Air Conditioning (A/C) is always on - Air Conditioning (A/C) mode always commanded ON | Refer to the Pinpoint Test | GO to Pinpoint Test I |
| Temperature control is inoperative/does not operate correctly | Refer to the Pinpoint Test | GO to Pinpoint Test J |
| The blower motor is inoperative | Refer to the Pinpoint Test | GO to Pinpoint Test K |
| The blower motor does not operate correctly | Refer to the Pinpoint Test | GO to Pinpoint Test L |
| A/C pressure relief valve discharging | High system pressure A/C pressure relief valve |
CHECK the high side system pressure. If the pressure is below the A/C pressure relief valve open pressure, REPLACE the A/C compressor. For 1. 0L EcoBoost Refer to : Air Conditioning (A/C) Compressor - 1. 0L EcoBoost (92kW/125PS) . For 2. 0L Duratec-HE Refer to : Air Conditioning (A/C) Compressor - 2. 0L Duratec-HE (125kW/170PS) - MI4 . For 2. 0L Ecoboost Refer to : Air Conditioning (A/C) Compressor - 2. 0L EcoBoost (184kW/250PS) - MI4 . If the system pressure is above the A/C pressure relief valve open pressure, REPAIR the 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 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. |
