Exhaust Brake/Warm Up Enable
OEM
ALSO KNOWN AS “ EXHAUST BRAKE CONFIGURATION”
Description:
The Exhaust Brake Confi guration parameter determines
the functionality of the exhaust brake. This parameter
can be programmed to one of the following options:
None, Warm Up Device Only, Exhaust Brake Only, or
Exhaust Brake & Warm Up Device.
The exhaust brake can be used to apply a parasitic
load to the engine in order to aid engine warm up to
achieve normal operating temperature quicker. To
use this feature, the Exhaust Brake Confi guration
parameter must be set to either Warm Up Device Only
or Exhaust Brake and Warm Up Device. Also, the Warm
Up Mode Idle Speed parameter must be programmed
to an engine speed between 700 rpm and 1400 rpm. If
these preceding conditions are met, then the engine
will ramp up to the programmed Warm Up Mode Idle
Speed parameter value when the intake air temperature
is below 50 degrees Fahrenheit and the coolant
temperature is below 160 degrees Fahrenheit.

brake, a warm up device to help the engine achieve
operating temperature quicker, or a combination of the
two. This allows fl exibility in the use of the exhaust
brake depending upon the specifi c application.
