13.0 Driveline Protection
Overview
The Driveline Protection feature provides three different types of engine torque
curves: Driveline Protection, Standard, and Multi-Torque (MT). Driveline Protection
reduces the maximum torque curve to protect driveline components when the
drivetrain reduction is calculated to be above a specific ratio. The Standard provides
the advertised torque curves in the Ratings section of this document when Driveline
Protection and MT are not active. MT provides a maximum torque curve for use in
the top two gears of rated transmissions and is only available with the MT engine
ratings.

Standard provides normal operation of the advertised torque curve.

Driveline Protection allows the engine to provide 950 lbf-ft maximum available torque
to specified lower limit. The engine will automatically reduce the maximum available
torque when it detects a transmission gear reduction of 15.0:1 or greater. This
functionality protects the driveline only in condition 1 or 2 below; otherwise it provides
the rated torque in all other conditions.
1. Vehicle has an auxiliary transmission with gear ratio greater than 1.0:1
2. Vehicle has a transmission in a forward or reverse gear with a gear ratio
equal to or greater than 15.0:1
Driveline protection is automatically included within the programming for all
multi-torque engine ratings, but will only be enabled if/when one of the above
conditions is met. This function is required/included with the multi-torque
ratings as it uses the same software function to enable the higher torque
values of the multi-torque rating.
Startability is not impacted with this function. The function only becomes
enabled after vehicle speed is greater than zero and the engine is able to
calculate the transmission ratio in use.
