Dual Automatic Temperature Control Module - Display Continuous Codes

WARNING: This page is about a different car, the 2004 Lincoln Town Car. However, it is still accessible from the selected car via links, so may be relevant.

This function will display continuous (intermittent) codes and hard faults that occur during normal operation.
The display of continuous codes can be initiated at any time. Normal operation of the system stops when the display of continuous codes is activated. Note that "° C" will be displayed while in this mode.
To display continuous codes, press the OFF and PANEL buttons simultaneously and then release and within two seconds press the AUTO button.
To exit the display of continuous codes, press the FRONT DEFROST button. This will exit and clear all DTCs. Press the FLOOR button to exit without clearing DTCs set before the last ignition cycle.
Always exit continuous codes display before powering the system down (system turned off).
Continuous DTCs are saved only after an ignition cycle.
Continuous DTCs will be deleted after 80 ignition switch ON cycles after the intermittent condition occurs.
