    • Using a scan tool, perform BCM self-test.

    Are any climate control related Diagnostic Trouble Codes (DTCs) present? 

    1. Yes:  Refer to BODY CONTROL MODULE (BCM) DTC CHART  .
    2. No:  GO to D3
  3. D3 CHECK THE HVAC (HEATING, VENTILATION AND AIR CONDITIONING) MODULE FOR DIAGNOSTIC TROUBLE CODES (DTCS) 
    • Ignition ON.
    • Using a scan tool, perform HVAC control module self-test.

    Are any Diagnostic Trouble Codes (DTCs) present? 

    1. Yes:  Refer to HVAC control module DTC chart .
    2. No:  GO to D4
  4. D4 CHECK THE BLOWER MOTOR OPERATION 
    • Ignition ON.

    • Observe blower motor operation and select each blower motor speed.

    Does the blower motor operate in all ranges? 

    1. Yes:  GO to D5
    2. No:  If the blower motor does not operate in any setting, GO to Pinpoint Test M 

      If the blower motor does not correctly change speeds or turn off when the system is turned off, GO to Pinpoint Test N 

  5. D5 CHECK AIRFLOW OPERATION 
    • Select the highest blower motor setting.
    • While observing the airflow, select each of the airflow positions (register, register/footwell, footwell, footwell/defrost, defrost).

    Is the airflow directed to the correct outlets? 

    1. Yes:  GO to D6
    2. No:  GO to Pinpoint Test F 
  6. D6 VERIFY TEMPERATURE CONTROL OPERATION 
    • Start the vehicle and allow it to reach normal operating temperature.
    • With the AC off, select register 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? 

    1. Yes:  GO to D7
    2. No:  If the temperature does not get very warm, GO to Pinpoint Test G 

      If the LH temperature does not change at all, GO to Pinpoint Test K 

      If the RH temperature does not change at all, GO to Pinpoint Test L 

  7. D7 VERIFY THE A/C (AIR CONDITIONING) CLUTCH DOES NOT ENGAGE WITH A/C (AIR CONDITIONING) OFF 
    • With the engine running and the A/C off, select register mode.
    • Select the coldest temperature setting.

    Is the outlet temperature close to ambient temperature? 

    1. Yes:  GO to D8
    2. No:  If the LH temperature is warmer than ambient temperature, GO to Pinpoint Test K 

      If the RH temperature is warmer than ambient temperature, GO to Pinpoint Test L 

      If the outlet temperature is significantly colder than ambient temperature and PCM DTC P1464:00 is present, GO to Pinpoint Test J 

      If the outlet temperature is significantly colder than ambient temperature and PCM DTC P1464:00 is not present, GO to Pinpoint Test I 

  8. D8 VERIFY A/C (AIR CONDITIONING) CLUTCH ENGAGEMENT IN THE A/C (AIR CONDITIONING) MODE 
    • Make sure the ambient air temperature is above 6 C (43 F).
    • With the engine running, select register mode.
    • Press the A/C button (indicator on).

    Does the A/C clutch engage when the register and A/C button (indicator on) is pressed? 

    1. Yes:  GO to D9
    2. No:  GO to Pinpoint Test H 
  9. D9 CHECK THE RECIRCULATED AIR OPERATION 
    • With the engine running, press the recirculated air button (indicator off).
    • Select register 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)? 

    1. Yes:  If the vehicle is not equipped with Sony® sound, the system is operating normally.

      If the vehicle is equipped with Sony® sound, GO to D10

    2. No:  GO to Pinpoint Test E 
  10. D10 CHECK THE LDFTEMP PID 
    • Using a scan tool, view the HVAC control module PIDs.
    • Monitor the LDFTTEMP PID.

    Is the temperature coming out of the left footwell vent similar to the PID? 

    1. Yes:  GO to D11
    2. No:  GO to Pinpoint Test O 
  11. D11 CHECK THE LDPT PID 
    • Using a scan tool view the HVAC control module PIDs.
    • Monitor the LDPT PID.

    Is the temperature coming out of the left register vent similar to the PID?
