4. Engine torque limitation

Maximum permissible air mass/combustion varies depending on the engine variant. During operation, the maximum permissible air mass/combustion must also be limited to protect the engine, gearbox, brakes or turbo.

External units, such as the automatic transmission, can also limit the maximum permissible air mass/combustion. Limitation can also take place in case of a system fault. The control module selects the lowest value. The value is sent to box 5.
