HVAC Module - Dual Automatic Temperature Control (DATC) - Retrieve Continuous DTCs
WARNING: This page is about a different car, the 2008 Mercury Sable, 2008 Ford Taurus X, and 2008 Ford Taurus. However, it is still accessible from the selected car via links, so may be relevant.
The HVAC module - DATC will retrieve only continuous (intermittent) DTCs when carrying out this procedure.
- Retrieval of continuous DTCs can be initiated after cycling the ignition switch from OFF to ON. Normal operation of the climate control system stops when retrieving continuous DTCs.
- To retrieve continuous DTCs, press the OFF and DEFROST buttons simultaneously and release, then press the RECIRC button within 2 seconds. All vacuum fluorescent segments will be displayed if there are no continuous DTCs present. Continuous DTCs are indicated by the presence of the Celsius symbol (°C) on the HVAC module - DATC display. Record all DTCs displayed.
- If any DTCs appear, carry out the diagnostic procedure. Refer to the HVAC Module DTC Table and follow the ACTION for each DTC given.
- If a condition exists but no DTCs appear, go to Symptom Chart - Climate Control Systems .
- To exit and retain all continuous DTCs, press any button except DEFROST. The HVAC module - DATC will exit and retain all continuous DTCs.
- To exit and clear all continuous DTCs, press the DEFROST button. The HVAC module - DATC will exit and all continuous DTCs will be cleared.
- Always exit the procedure before powering the system down (system turned OFF). Once the procedure is exited, the ignition switch must remain ON for at least 30 seconds to allow the door actuators to automatically recalibrate.
- Continuous DTCs will be deleted after 80 ignition switch ON cycles after the intermittent fault occurs.
