    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 2°C (36°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 (PARAMETER IDENTIFICATION) 
    • Using a diagnostic scan tool, view the HVAC  control module Parameter Identifications (PIDs).
