Diesel Exhaust Fluid (DEF) Fault Warning
Messages – Chassis Cab Only
There are three different messages which are displayed if
the vehicle detects that the DEF system has been filled
with a fluid other than DEF, has experienced component
failures, or when tampering has been detected. The
vehicle will not start if the DEF system is not serviced
within less than 250 miles (402 km) of the fault being
detected.
When the DEF system needs to be serviced the following
warnings will display:
•
Service DEF System – See Dealer
— This message
will display when the fault is initially detected, each
time the vehicle is started, and periodically during
driving. The message will be accompanied by a single
chime. We recommend you drive to your nearest
authorized dealer and have your vehicle serviced as
soon as possible.
•
Service DEF System Engine Will Not Start In
200 Miles – See Dealer
— This message will display if
the DEF system has not been serviced after the “Ser-
vice DEF System – See Dealer” message is displayed.
This message will continuously display until the mile-
age counter reaches zero, and will be accompanied by
a periodic chime. The message will continue to count-
down until it reaches zero unless the vehicle is ser-
viced. We recommend you drive to your nearest
authorized dealer and have your vehicle serviced
immediately.
NOTE:
Under some circumstances this mileage counter
may start with a value of less than 200 miles (322 km). For
example, if recurring faults are detected in a time interval
of less than 40 hours, the counter may restart at the value
where it stopped when a previous fault was temporarily
remedied, or at a minimum of 50 miles (80 km).
