DESCRIPTION
Since a loss of data communication with the Climate Control Driver Information Center (CCDIC) will result in a "System Problem" display, this code can only be recognized as a "History" code. During this event, The Heating Ventilation and Air Conditioning (HVAC) will divert to 24°C (75°F) set temperature, front defrost air delivery and automatic blower control.

With a two-way, redundant communication ability built into this system, a double open in the data line must occur to set the fault. A single fault, however, in the CCDIC power or ground would also cause this code to set.
