Pinpoint Test C : Unable To Duplicate The Customer Concern And No Diagnostic Trouble Codes (DTCS) Present

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.

C1 CHECK THE PCM (POWERTRAIN CONTROL MODULE) FOR DIAGNOSTIC TROUBLE CODES (DTCS)
- Ignition ON.
- Using a scan tool, perform PCM self-test.
Are any climate control related Diagnostic Trouble Codes (DTCs) present?

Yes REFER to the DTC Chart: Powertrain Control Module (PCM) .

No GO to C2

C2 CHECK THE FCIM (FRONT CONTROLS INTERFACE MODULE) FOR DIAGNOSTIC TROUBLE CODES (DTCS)
- Ignition ON.
- Using a diagnostic scan tool, perform FCIM self-test.
Are any Diagnostic Trouble Codes (DTCs) present?

Yes REFER to the DTC Chart: Front Controls Interface Module (FCIM) - Dual Automatic Temperature Control (DATC) .

No GO to C3

C3 CHECK THE BLOWER MOTOR OPERATION

Ignition ON.

Select panel mode.

Observe blower motor operation and select each blower motor speed.

Does the blower motor operate in all ranges?

Yes

GO to C4

No	If the blower motor does not operate in any setting, GO to Pinpoint Test K . If the blower motor does not correctly change speeds or shut off, GO to Pinpoint Test L

C4 CHECK AIRFLOW OPERATION
- Select the highest blower motor setting.
- While observing the airflow, select each of the airflow positions (panel, panel/floor, floor, floor/defrost, defrost).
Is the airflow directed to the correct outlets?

Yes GO to C5

No GO to Pinpoint Test E

C5 VERIFY TEMPERATURE CONTROL OPERATION

Start the vehicle and allow it to reach normal operating temperature.

With the A/C off, select panel mode.

Change the driver and passenger temperature settings from the coldest to the warmest and back to the coldest.

Does the temperature change between very warm to cool?

Yes

GO to C6

No	If the temperature does not get very warm, GO to Pinpoint Test F . If the LH temperature does not change at all, GO to Pinpoint Test I . If the RH temperature does not change at all, GO to Pinpoint Test J .

C6 VERIFY THE AIR CONDITIONING COMPRESSOR DOES NOT ENGAGE WITH A/C (AIR CONDITIONING) OFF

With the engine running and the A/C off, select panel mode.

Select the coldest temperature setting.

Is the outlet temperature close to ambient air temperature?

Yes

GO to C7

No	If the LH temperature is warmer than ambient air temperature, GO to Pinpoint Test I . If the RH temperature is warmer than ambient air temperature, GO to Pinpoint Test J . If the outlet temperature is significantly colder than ambient air temperature and the A/C compressor clutch is engaged, GO to Pinpoint Test H .

C7 VERIFY THE A/C (AIR CONDITIONING) COMPRESSOR IS OPERATIONAL IN THE A/C (AIR CONDITIONING) MODE
- Make sure the ambient air temperature is above approximately 0°C (32°F).
- With the engine running, select panel mode.
- Press the A/C button (indicator on).
Is the A/C compressor operational when the panel and A/C button (indicator on) is pressed?

Yes GO to C8

No GO to Pinpoint Test G

C8 CHECK THE RECIRCULATED AIR OPERATION
- With the engine running, press the recirculated air button (indicator off).
- Select panel mode.
- Select the highest blower motor setting.
- Observe airflow noise.
- Press the recirculated air button (indicator on).
Does the airflow noise increase when the recirculated air mode is selected (indicator on)?

Yes GO to C9

No GO to Pinpoint Test D

C9 CHECK THE FCIM (FRONT CONTROLS INTERFACE MODULE) LEFT DISCHARGE FLOOR TEMPERATURE (LDFTEMP) PID (PARAMETER IDENTIFICATION)
- Using a diagnostic scan tool, view the FCIM Parameter Identifications (PIDs).
- Monitor the LDFTEMP PID.
Is the temperature coming out of the driver footwell vent similar to the PID?

Yes GO to C10

No GO to Pinpoint Test M

C10 CHECK THE FCIM (FRONT CONTROLS INTERFACE MODULE) LEFT DISCHARGE PANEL TEMPERATURE (LDPT) PID (PARAMETER IDENTIFICATION)
- Using a diagnostic scan tool, view the FCIM Parameter Identifications (PIDs).
- Monitor the LDPT PID.
Is the temperature coming out of the driver side register similar to the PID?

Yes GO to C11

No GO to Pinpoint Test M

C11 CHECK THE FCIM (FRONT CONTROLS INTERFACE MODULE) DISCHARGE AIR TEMPERATURE RIGHT FLOOR (AIRTEMP_RF) PID (PARAMETER IDENTIFICATION)
- Using a diagnostic scan tool, view the FCIM Parameter Identifications (PIDs).
- Monitor the AIRTEMP_RF PID.
Is the temperature coming out of the passenger footwell vent similar to the PID?

Yes GO to C12

No GO to Pinpoint Test M

C12 CHECK THE FCIM (FRONT CONTROLS INTERFACE MODULE) DISCHARGE AIR TEMPERATURE RIGHT PANEL (AIRTEMP_RP) PID (PARAMETER IDENTIFICATION)
- Using a scan tool view the FCIM Parameter Identifications (PIDs).
- Monitor the AIRTEMP_RP PID.
Is the temperature coming out of the passenger side register similar to the PID?

Yes GO to C13

No GO to Pinpoint Test M

C13 CHECK THE FCIM (FRONT CONTROLS INTERFACE MODULE) INTERIOR TEMPERATURE SENSOR (INT_TEMP) PID (PARAMETER IDENTIFICATION)
- Using a scan tool view the FCIM Parameter Identifications (PIDs).
- Monitor the INT_TEMP PID.
Is the air temperature at the cabin temperature sensor similar to the PID?

Yes GO to C14

No GO to Pinpoint Test N

C14 CHECK THE TOUCHSCREEN CONTROLS OPERATION
- Using the touchscreen controls, select each climate control function.
- Using the touchscreen controls, select each audio control function.
Do all touchscreen controls operate?

Yes The system is operating correctly.

No REFER to: Information and Entertainment System .
