Urea System Fault screens appear when a low voltage or charger/battery issue for the Urea
components has been detected by the V-MAC system.
The two screens that appear are
Urea System Low Voltage
and
Urea System Fault Check
CHARGER/BATTERY . The Urea System Low Voltage screen displays if the urea system
is receiving low voltage. Low voltage can inhibit the proper function of the urea system.
The
Urea System Fault Check CHARGER/BATTERY screen displays if there is a fault
with the urea system battery or charger. A battery or charger issue can adversely affect the
Urea system’s operation. Also, the Electronic Malfunction Indicator lamp illuminates up in
the Instrument Cluster for both these fault messages..
