DTC Chart: Front Controls Interface Module (FCIM) - Electronic Manual Temperature Control (EMTC)

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. For information about these practices,
REFER to: Diagnostic Methods (100-00 General Information, Description and Operation).

Network Diagnostic Trouble Codes (DTCs) (U-codes) are often a result of intermittent concerns such as damaged wiring or low battery voltage occurrences. Additionally, vehicle repair procedures, such as module reprogramming, often set network Diagnostic Trouble Codes (DTCs). Replacing a module to resolve a network DTC is unlikely to resolve the concern. To prevent repeat network DTC concerns, inspect all network wiring, especially connectors. Test the vehicle battery.

Normal Operation and Fault Conditions

Door Actuator – Air Inlet Door, REFER to: Climate Control System - Vehicles With: Electronic Manual Temperature Control (EMTC) - System Operation and Component Description (412-00 Climate Control System - General Information, Description and Operation).

During an actuator calibration cycle, the FCIM drives the air inlet mode door until the door reaches both internal stops in the HVAC case. If the air inlet mode door is temporarily obstructed or binding during a calibration cycle, the FCIM may interpret this as the actual end of travel for the door. When this condition occurs and the FCIM commands the actuator to its end of travel, the air intake may not be from the expected source.

Normal Operation and Fault Conditions

Temperature Door Actuator , REFER to: Climate Control System - Vehicles With: Electronic Manual Temperature Control (EMTC) - System Operation and Component Description (412-00 Climate Control System - General Information, Description and Operation).

During an actuator calibration cycle, the FCIM drives the temperature door until the door reaches both internal stops in the HVAC case. If the temperature door is temporarily obstructed or binding during a calibration cycle, the FCIM can interpret this as the actual end of travel for the door. When this condition occurs and the FCIM commands the actuator to its end of travel, the airflow may not be the expected temperature.

Ford Fusion. Climate Control System - Vehicles With: Electronic Manual Temperature Control (EMTC). Diagnosis and Testing PINPOINT TEST K : THE BLOWER MOTOR DOES NOT OPERATE CORRECTLY

Refer to Wiring Diagrams Cell 54 for schematic and connector information.

Normal Operation and Fault Conditions

Voltage is supplied to the blower motor relay switch contacts from the BJB. The blower motor relay coil is supplied voltage by the FCIM. When the relay coil is energized and voltage is delivered to the blower motor speed control. Power and ground for the blower motor is provided by the blower motor speed control. The FCIM sends a Pulse Width Modulated (PWM) signal to the blower motor speed control to control the blower speed.

DTC Fault Trigger Conditions

DTC Description Fault Trigger Condition

Ford Fusion. Climate Control System - Vehicles With: Electronic Manual Temperature Control (EMTC). Diagnosis and Testing PINPOINT TEST L : AIR DISCHARGE TEMPERATURE SENSOR CIRCUIT FAULTS

Refer to Wiring Diagrams Cell 54 for schematic and connector information.

Normal Operation and Fault Conditions

The air discharge sensors supply a varying voltage to the FCIM based on the temperature of the air being discharged from the vent. The module adjusts the system based on the voltage from each sensor.

Each air discharge sensor is supplied voltage from the module and all sensors share a common sensor ground. An open, a short to ground, a short to voltage on one or more of these circuits or a failed air discharge sensor causes the FCIM to set one or more Diagnostic Trouble Codes (DTCs).

Refer to Wiring Diagrams Cell 54 for schematic and connector information.

Normal Operation and Fault Conditions

The externally controlled variable displacement compressor is electronically controlled by the PCM. The PCM pulse width modulates the ground to the externally controlled variable displacement compressor to change the displacement of the A/C compressor. REFER to: Climate Control System - Vehicles With: Electronic Manual Temperature Control (EMTC) - System Operation and Component Description (412-00 Climate Control System - General Information, Description and Operation).

DTC Fault Trigger Conditions

DTC Description Fault Trigger Condition
PCM P06A0:00 Variable A/C Compressor Control Circuit: No Sub Type Information This DTC sets when the PCM senses greater than expected voltage on the sensor feedback circuit, indicating a short to voltage or an open circuit or an open sensor.

Possible Sources

  • Fuse
  • Wiring, terminals or connectors
  • Low refrigerant charge
  • A/C compressor
  • PCM

Visual Inspection and Pre-checks

  • Inspect for loose or corroded PCM and A/C compressor connections.
  • Make sure BJB fuse 12 (15A) is OK.

NOTE: The following pinpoint test step uses the EVDC100 Electronic Variable Displacement A/C Compressor Control Valve Tester, available on the Ford Rotunda website. If you do not have the EVDC100 Electronic Variable Displacement A/C Compressor Control Valve Tester, go to step 2 of this pinpoint test.

NOTE: Proper Air Conditioning (A/C) system diagnosis on a vehicle's compressor is dependent on correct refrigerant system charge and tested in ambient temperatures above 21.1°C (70°F).

  • Test the EVDC compressor displacement, following the instructions in the user manual supplied with the Model EVDC100 A/C Compressor Electronic Control Valve Tester.

Did the suction low side pressure decrease or the high side pressure increase?

Q2 EXTERNALLY CONTROLLED VARIABLE DISPLACEMENT COMPRESSOR (EVDC) PERFORMANCE CHECK WITHOUT THE AC COMPRESSOR ELECTRONIC CONTROL VALVE TESTER

NOTE: Proper Air Conditioning (A/C) system diagnosis on a vehicle's compressor is dependent on correct refrigerant system charge and tested in ambient temperatures above 21.1°C (70°F).

NOTE: The performance check test is used to determine if the Externally Controlled Variable Displacement Compressor (EVDC) is able to change the displacement by monitoring PCM Parameter Identifications (PIDS) soon after the air conditioning clutch is engaged.

  • Start the engine.
  • Using a diagnostic scan tool, view PCM Parameter Identifications (PIDS).
  • Using a diagnostic scan tool, monitor EVACC PID.
  • Select the floor position on the HVAC controls. Set the temperature control to full warm and the blower to the lowest setting. Set the A/C to off. Close all windows and doors. Run for 5 minutes to heat up the climate control housing.
  • Select the PANEL position on the HVAC controls. Set the temperature control to full cold and the blower to the highest setting. Set the recirc mode to on. Set the A/C to on.

Did the PID initially increase and then decrease?
Yes The Externally Controlled Variable Displacement Compressor (EVDC) is able to change the displacement. Do not replace the compressor. CHECK refrigerant charge amount. REFER to the appropriate general procedure in Group 412-00.
No GO to Q3

    Understanding Your Tire Pressure Monitoring System

    Ford Fusion. Understanding Your Tire Pressure Monitoring System

    The tire pressure monitoring system measures pressure in your road tires and sends the tire pressure readings to your vehicle. You can view the tire pressure readings through the information display. The low tire pressure warning light will turn on if the tire pressure is significantly low. Once the light is illuminated, your tires are under-inflated and need to be inflated to the manufacturer’s recommended tire pressure. Even if the light turns on and a short time later turns off, your tire pressure still needs to be checked.
