Daimler Trucks North America engine control module software may be calibrated incorrectly, causing the engine to not limit engine speed or torque as intended for certain safety-related functions such as vehicle braking, traction and stability control, speed control, or collision avoidance.
The short version
Daimler Trucks North America, LLC reported a problem with the engine control module (ecu/ecm) software. Here is what owners need to know.
The engine control module software may be calibrated incorrectly, causing the engine to not limit engine speed or torque as intended for certain safety-related functions such as vehicle braking, traction and stability control, speed control, or collision avoidance.
If safety-related functions such as vehicle braking, stability, speed, and collision avoidance do not function properly, it can increase the risk of a crash.
DTNA will work with the engine manufacturer Cummins Inc. to notify owners, and Cummins dealers will recalibrate the engine control module, free of charge.
